Background: Syzygium densiflorum is a vulnerable tree species belonging to the Myrtaceae family. Objective: To investigate the influence of altitudinal variation on the anti-oxidant potential of leaf essential oil of Syzygium densiflorum. Materials and Methods: The leaf essential oil has been isolated using hydrodistillation process and their scavenging ability was determined using five in vitro assays such as 2, 2-diphenyl-1-picrylhydrazyl (DPPH), ferric reducing anti-oxidant power (FRAP), 2, 2′-Azino-bis (3- ethylbenzothiazoline-6-sulphonic acid) (ABTS), hydrogen peroxide (H 2 O 2 ) and hydroxyl radical scavenging assays. Statistical analysis: The results were analysed statistically using one-way analysis of variance (ANOVA) following Duncan′s multiple range test. Results: Leaves from lower altitude showed higher activity against hydrogen peroxide, hydroxyl radical and ferric ion and moderate activity against DPPH and ABTS free radicals. Leaves from higher altitude essential oil exhibits potent activity against hydrogen peroxide and hydroxyl radical compared with the standard. Conclusions: Comparatively lower altitude leaf essential oil showed potent anti-oxidant activity confirming the fact that altitudinal variations have profound effect on the anti-oxidant potential of Syzygium densiflorum.

Background: Hopea ponga has been categorised as an endangered tree species under International Union for Conservation of Nature red list of threatened species. Objective: To study the antibacterial, antioxidant activities, total phenolic and flavonoid contents of Hopea ponga leaf, extracted from different solvents viz., petroleum ether, chloroform and methanol. Materials and Methods: Antibacterial activity of leaf extract of Hopea ponga was determined by disc diffusion method against Escherichia coli, Proteus vulgaris, Bacillus cereus, Streptococcus faecalis and Pseudomonas aeruginosa. The antioxidant activities of the extracts were assayed through in-vitro models such as 2,2-diphenyl-1- picrylhydrazyl, 2,2′- azino-bis (3-ethylbenzothiazoline-6-sulphonic acid), ferric reducing antioxidant power, hydrogen peroxide and hydroxyl scavenging activities. Total flavonoid content was determined using aluminium chloride colorimetric method and total phenolic content determined using Folin ciocaulteu reagent method. Results : Methanol extract showed higher scavenging activity against 2,2-diphenyl-1-picrylhydrazyl and reducing power activity against ferric ion (97.24 ± 0.11 and 88.01 ± 0.03) compared to other extracts. Methanol extract showed significant antibacterial activity against P. vulgaris and B. cereus. Among the tested extracts, methanol extract exhibited higher content of phenols (1318.749 mg of ferulic acid equivalent/100 gram dry weight of extract) and flavonoids (457.832 mg of quercetin equivalent/100 gram dry weight of extract). Conclusions : The present study suggests that the methanol extract may contain active compounds, which have effective antioxidant and antimicrobial activity. Hence, this endangered species have to be explored and conserved to serve the mankind.

Introduction: Hemiplegia and the Ayurvedic description of ardhanga disease presents with comparable clinical features. This pilot trial compared two traditional procedure-based treatments: Navarakizhi, a massage of cooked navara rice in a medicated hot bolus, and pinda sweda, a similar massage made of a different type of rice. This article also describes the steps of a double-blind trial in Ayurveda, which was hitherto considered difficult to perform. Methods: Eighteen (18) patients suffering from hemiplegia with disease duration of 6 months to 2 years received treatment with navarakizhi or pinda sweda for 7 days. Both groups received the same Ayurvedic oral medications for 14 days. All steps of randomization and blinding of procedure-based therapy in Ayurveda are described. The physiotherapist evaluated muscle tone, muscle strength, tendon reflexes, range of movement, and balance of functional abilities at baseline, 7 days, and 14 days after starting therapy. Both patient and the assessing physiotherapist were blinded. Results: Intraquartile range values showed better range in patients who received navarakizhi than those who received pinda sweda. Discussion: A larger trial is needed to confirm the superiority of navarakizhi over the rice varieties in treating hemiplegia. This study demonstrates that double-blind randomized clinical trials are possible in Ayurvedic settings, ending the long-debated controversy in trial methodology involving procedure-based traditional medicines. © Copyright 2014, Mary Ann Liebert, Inc. 2014.

Wayanad Wildlife Sanctuary, situated in the Wayanad revenue district of Kerala, India falls under Nilgiri Biosphere Reserve on the Western Ghats. Floristic and ethnobotanical studies in the sanctuary resulted in the documentation of a total of 75 taxa of trees of ethnobotanical importance, and their uses by Kattunaikka tribe residing within the sanctuary are recorded. The potentialities of the medicinal properties of the trees are important and could be explored and utilized in the pharmaceutical industry. ©2011 Academic Journals.

Miliusa gokhalaei (Annonaceae), a new species from the Western Ghats, India, is described and illustrated. It is distinguished by unequal rounded leaf bases, sessile or shortly pedicellate flowers, thick fleshy petals, glabrous carpel, and included connective of anther. It is closely related to M. indica and M. eriocarpa, with which it shares sub-sessile or shortly petiolate, hairy-nerved leaves, axillary solitary flowers, and flask-shaped carpel with 1-2 ovules. Notes on interrelationships, population structure, conservation status and an identification key to the taxa of Miliusa in peninsular India are also provided. © 2012 Magnolia Press.

Wayanad district is with a hilly terrain on the southern Western Ghats and located in the northeast part of Kerala state. The ethnic diversity of the district is very impressive as evidenced by ten different tribal groups. Ethnobotanical studies in the district resulted in the documentation of information on 165 edible plants used by Kattunaikka, Paniya and Kuruma tribes. The Paniya community possesses knowledge regarding 136 taxa of wild edible plants, with Kattunaikkas coming next with knowledge of 97 taxa. Amongst these tribal communities, the Kurumas are at the bottom of the knowledge-ladder with knowledge of 42 taxa of wild edible plants. © 2011 Academic Journals.
