Andrographis paniculata (Burm.f.) Nees (Acanthaceae) is a medicinal plant traditionally used for the treatment of cold, fever, laryngitis and several infectious diseases ranging from malaria to dysentery and diarrhoea. The plant is widely used in Ayurvedic and Homeopathic systems of medicines. The medicinal value of this plant is due to the presence of active ingredients viz andrographolide and neoandrographolide which are derivatives of diterpenoids. The content of these active ingredients in plant varies with in plant parts and with the geographical distribution. In order to study the variation in andrographolide content, plant material was collected from 15 districts of Madhya Pradesh and evaluated through a simple, quick and accurate HPLC method using C-18 ODS-2 column. The chemoprofiling study showed significant variations in the concentration of active ingredients in the leaves as well as in whole plant. The study also revealed that andrographolide content was maximum in leaves of the accession collected from Seoni(1.82%) followed by Chhindwara (1.48%).

Non-timber forests products (NTFPs) provide multiple livelihood benefits to local communities and regional and national economies. And yet this knowledge is rarely drawn upon in debates around and design of poverty alleviation or land use policies, strategies and projects. Unless the accumulating wealth of empirical evidence can be translated into policies and approaches at higher levels, and integrated into poverty alleviation programmes, it will have little impact on local and national poverty profiles. In this paper we propose and briefly discuss eight steps to facilitate integration of NTFPs into the development agenda, for the benefit of local communities. These include: (1) proper inventory of NTFP stocks, (2) research on NTFP ecology and sustainable harvest levels, (3) introduction of extension services for NTFPs, (4) inclusion of NTFPs in land management and trade-off decisions, (5) integration of NTFPs into sectoral policies, (6) ensuring NTFP commercialisation is not at the expense of local livelihood needs, (7) promoting security of access and use, and (8) examination of local contextual drivers of unsustainable use. Each is presented along with examples or proposals towards implementation. © 2013 Elsevier B.V.

Embelia tsjeriam-cottam Roem & Schult A. DC. (Myrsinaceae), popularly known as Vaividang, is a vulnerable forest species because of the high demand of fruits for medicinal purposes. It is in great demand in ayurveda and the pharmaceutical industry (>100. t/yr), which has imposed tremendous pressure on some natural populations. The fruits contain embelin (a benzoquinone derivative), which has wide clinical applications. Considering the importance, growing use and decreasing populations in some areas of its natural habitat, a study on development of sustainable harvesting practices of E. tsjeriam-cottam fruits was conducted in Chhattisgarh, in central India. Experiments were laid out in Dhamtari, Marvahi and Bilaspur forest divisions of the state covering both protected and open forests in a randomized design with three replications. At each site, quadrats of 40 × 20 m were laid out to study the effect of two fruit harvesting methods and four harvesting intensities on fruit yield, and regeneration of the species. Fruits were analyzed for their embelin content by HPLC method. This study is the first to experimentally assess the consequences of harvesting of E. tsjeriam-cottam fruits from India. It was found that up to 70% fruits could be hand plucked at the right time of maturity (December) to obtain quality produce without impacting the current population size. Since every year is not a good fruiting year, it is difficult to develop universal harvest regime for sustainable management of E. tsjeriam-cottam. The embelin content increased as fruits ripened, ranging from 1.01% to 5.63%. The adoption of sustainable harvesting practices will be helpful in sustainable management of E. tsjeriam-cottam and also provide income and livelihood opportunities to rural people on a sustainable basis. © 2011 Elsevier B.V.

Terminalia bellerica Roxb. (Belleric myrobalan) is one of the important multipurpose trees in central India. The fruits of the tree are highly valued for medicinal uses, with the greatest demand coming from the pharmaceutical industry. This has resulted in overexploitation and present harvesting practices have led to a significant decline in natural regeneration for this tree species. Our study was conducted from 2006 to 2009 in Chhattisgarh (India) to standardize suitable harvesting practices for sustainable management for this valuable species. Experiments were conducted at four different sites located in Dhamtari, Sarguja, and Raigarh forest divisions of the state, covering both protected and open forest in a complete randomized block design (RCBD). At each site, linear transects of 200 m × 100 m (2 ha) were randomly selected to sample the initial population and study the effects of two harvesting methods (traditional and nondestructive) and four harvesting intensities (60%, 70%, 80%, and 90%) on the sustainability of T. bellerica. Fruits were collected and analyzed for their tannin and gallic acid content. Significant increase in tannin and gallic acid content was found with the maturity of fruits (September to December). This is the first study to experimentally assess the consequences of harvesting of T. bellerica fruits in central India. Our findings reveal that harvesting intensity, time, and method are key factors for maintaining the population. Nondestructive harvesting methods were found to be superior to traditional harvesting in terms of regeneration, recruitment, and concentration of active ingredients. When the fruits were harvested through non-destructive means at maturity, the population of species increased. The study concludes that 70% harvest of T. bellerica fruits through non-destructive means maintains the sustainability and provides quality raw material for the pharmaceutical industry. © 2014 Northeast Forestry University and Springer-Verlag Berlin Heidelberg.

Apart from the diverse uses of bamboo, the tender shoots, being low in fat, high in dietary fiber and rich in mineral content (good source of potassium) have been consumed traditionally by the people. The shoots are consumed due to their exotic taste, flavour, medicinal and nutritive value. Bamboo shoots are available for a limited period and have a short shelf-life, thus, they need to be processed and utilized immediately after harvest. Therefore, a study was conducted to determine the nutritional value and develop value added edible products from different bamboo species viz., Dendrocalamus strict us, Bambusa bambos and Bambusa tulda, found in central India and Dendrocalamus asper (known edible bamboo species of Thailand) grown in central India. Nutritional analysis revealed that the nutritive value of D. strict us, B. bamboos and B. tulda is at par with D. asper. Thus, these species have a potential for edible shoot production in central India. Different value added products viz., nuggets (bari), pickle and papad (cracker) were made from fresh bamboo shoots. Organoleptic, sensory and chemical evaluation done at monthly intervals, to determine the shelf-life of product, revealed that the products were good in taste, texture and quality for 6 months from the date of processing at ambient conditions (25-40°C) in poly propylene and glass containers. Value addition (by making different edible products) will increase the utilization of bamboo shoots and provide livelihood opportunities to the local population. Present study will be useful in optimum utilization of bamboo shoots. © 2012 Academic Journals Inc.

Non destructive methods for quantification of carbon sequestration in tropical trees are inadequately developed. We described a standardized method for estimating carbon stock in teak (Tectona grandis Linn. F.). We developed linear allometric equations using girth at breast height (GBH), height and age to quantify above ground biomass (AGB). We used AGB to estimate carbon stock for teak trees of different age groups (1.5, 3.5, 7.5, 13.5, 18.5 and 23.5 years). The regression equation with GBH, y = 3.174x - 21.27, r 2=0.898 (p <0.01), was found precise and convenient due to the difficulty in determination of height and age in dense natural forests of teak. The equation was evaluated in teak agroforestry systems that included Triticum aestivum (wheat), Cicer arietinum (gram), Withania somnifera (ashwagandha), Avena fatua (wild oat) and Hordeum vulgare (barley) as agricultural crops established at Tropical Forest Research Institute, Jabalpur, M.P. (India). The annual carbon stock gain in teak in different agroforestry systems was in the order: teak-barley (60.47%) > teak-wheat (56.92%) > teak-wild oat (54.94%) > teak-gram (37.15%) > teak-ashwagandha (11.86%). The results from GBH-based regression equations provided satisfactory estimates of carbon stock in tropical trees. © 2013 Northeast Forestry University and Springer-Verlag Berlin Heidelberg.

Bamboo shoots can be harvested at different ages but the data on the changes in nutritional composition with age are scanty. We standardized harvesting age of bamboo shoots in central India to obtain best quality produce with respect to nutritional composition. The shoots harvested on different days (2-20 days after emergence from ground) were analyzed for their nutritional (dietary fibres, carbohydrates, proteins, total phenols, ascorbic acid, sodium, potassium, phosphorus, calcium, magnesium and phenolic acids) and anti nutritional (cyanogen) constituents. A significant variation (at p ≤ 0. 5) was observed in the nutritional composition of shoots of Dendrocalamus asper, D. strictus and Bambusa tulda harvested at different days. An overall decrease was observed in proteins and total phenols while dietary fibres and carbohydrates increased with ages. Significant variation (at p ≤ 0. 5) was also observed in phenolic acids while minerals did not vary significantly. Results revealed that the optimum harvesting age for D. asper, D. strictus and B. tulda was on 10-14 days, 6-10 days and 10-16 days (after emergence from the ground) respectively. These results can be used to obtain quality bamboo shoots. © 2012 Northeast Forestry University and Springer-Verlag Berlin Heidelberg.

Phytochemical estimation and radical scavenging activity were carried out in the barks of Bauhinia variegata, Saraca asoka and Terminalia arjuna collected from central India with the objective to determine optimum harvesting age (girth class). Bark samples were analyzed for total phenols, flavonoids and tannins. Radical scavenging activity of the barks was evaluated using DPPH assay. Significant variation was observed in total phenols and tannins in B. variegata; flavonoids and tannins in T, arjuna with respect to different girth classes. However, no significant variation was found in chemical constituents among different girth classes of S. asoka. Gallic acid was used as standard having IC 50 value of 1.06±0.10 μg mL -1. Radical scavenging activity showed significant variation in the barks of different girth classes of B. variegata, S. asoka and T. arjuna. The results revealed that the optimum girth class to harvest barks of B. variegata was 36-55 cm, S. asoka 61-90 cm and T. arjuna 121-150 cm as these were found to contain maximum concentration of active ingredients and possess high radical scavenging activity. Among the studied species T. arjuna showed maximum radical scavenging activity and thus can be termed as a potent antioxidant species whose bark can be used for making various formulations containing natural antioxidants. © 2011 Academic Journals Inc.

Wild edible fungus, Astraeus hygromatricus was analysed for its nutritional and anti nutritional contents. 11.71% and 4.66% protein content was recorded in outer part and inner part of the fruit bodies, respectively which is comparable with other edible mushrooms. Fruit bodies contain high carbohydrate content i.e., 29.48% and 35.41 % in outer and inner parts respectively. The ash content of A. hygrometricus is low (2.5%). Fungus samples are good source of minerals such as P, K, Ca, Mg, Fe, Zn and Mn. Two major vitamins i.e., water soluble vitamins, ascorbic acid and thiamine, were also found to be present in both inner and outer parts (3.26 and 0.26 mg/100g).

Saponins were isolated from the neoil bearing forest seeds viz., Maduca indica, Sapindus mukrossi and their herbicidal activities were assessed under laboratory conditions at different dilutions against Echinochloa colanum, a notorious weed of silvl-agri (babul-paddy) agroforesty model. The effect of dilutions viz., 2.5,5,10% of saponin isolates on % germination, and root and shoot length were recorded. The incorporation of 2.5 % concentration of saponin dilutions of different species drastically reduced germination (35-47%) as compared the control. No root formation was recorded in all treatments while 60.09-94.95% shoot length inhibition over control (3.27 cm) was recorded in different treatments. Screened species grow luxuriantly in tropical region and easily available source for the isolation of saponins, which can be utilized as a lead molecule forthe synthesis of safer, eco-friendly and more economical weed control agents.
