Ficus palmata, Pyrus pashia and Ficus auriculata are the popular wild edible fruits of Uttarakhand. The present study aimed to evaluate their total phenolic, flavonoid contents, antioxidant and antiproliferative activities by using two so vents namely 80% aqueous methanol and acetone. The results showed highest phenolic and flavonoid contents in the Ficus pa mata acetone extract, while lowest in Ficus auriculata and Pyrus pashia methanol extracts respectively. Antioxidant activities were highest in the acetone extract of Ficus palmata and Pyrus pashia respectively. RP-HPLC analysis revealed abunda ce of gallic acid and catechin in all the fruit extracts, while traces of caffeic acid, coumaric acid and ellagic acid.Allthe fruit extracts possessed antiproliferative activities (22-63%) against cervical cancer cells C33A being highest in Ficus palmata, while showing no cytotoxicity to the normal peripheral blood mononuclear cells. Therefore, Ficus palmata fruitextracts could be used for the developing herbal formulation that can reduce the oxidative stress and prevent cancer development. Source

Himalyan bayberry (Myrica esculenta) fruit in Indian Himalayan region was evaluated for total polyphenol contents, antioxidant, and anticancer activities in 4 different solvent systems namely 80% each of methanol, acidicmethanol, acetone, and acidic-acetone to ensure the optimum recovery. Himalyan bayberry acidic-acetone (MeAA) extracts showed highest recovery of phenolics, flavonoids, freeradical scavenging, and ferric-reducing activities followed by acetone (MeA), acidic-methanol (MeAM), and methanol (MeM) extracts. Both MeA and MeAA extracts showed potent anticancer activities leading to 70-92% reduction in the viability of C33A, SiHa, and HeLa cells while exhibiting no cytotoxicity towards normal transformed cell lines. The RP-HPLC analysis revealed abundance of gallic acid [793.74 mg/100 g of fruit weight (f.w.) in MeA], myricetin (345.6 mg/100 g f.w. in MeAA), caffeic acid (246.6 mg/100 g f.w. in MeM), catechin (190.181 mg/100 g f.w. in MeAA) while traces of chlorogenic acid (17.67 mg/100 g f.w. in MeAA), transcinnamic acid (5.91 mg/100 g f.w. in MeA), p-coumaric acid (5.84 mg/100 g f.w. in MeA), and ellagic acid (2.21 mg/100 g f.w. in MeA) corroborating the high antioxidant and anticancer activities of Himalyan bayberry fruit extracts. © 2013 The Korean Society of Food Science and Technology and Springer Science+Business Media Dordrecht.

A new bacterial strain DMT-7 capable of selectively desulfurizing dibenzothiophene (DBT) was isolated from diesel contaminated soil. The DMT-7 was characterized and identified as Lysinibacillus sphaericus DMT-7 (NCBI GenBank Accession No. GQ496620) using 16S rDNA gene sequence analysis. The desulfurized product of DBT, 2-hydroxybiphenyl (2HBP), was identified and confirmed by high performance liquid chromatography analysis and gas chromatography-mass spectroscopy analysis respectively. The desulfurization kinetics revealed that DMT-7 started desulfurization of DBT into 2HBP after the lag phase of 24 hr, exponentially increasing the accumulation of 2HBP up to 15 days leading to approximately 60% desulfurization of the DBT. However, further growth resulted into DBT degradation. The induced culture of DMT-7 showed shorter lag phase of 6 hr and early onset of stationary phase within 10 days for desulfurization as compared to that of non-induced culture clearly indicating the inducibility of the desulfurization pathway of DMT-7. In addition, Lysinibacillus sphaericus DMT-7 also possess the ability to utilize broad range of substrates as sole source of sulfur such as benzothiophene, 3,4-benzo DBT, 4,6-dimethyl DBT, and 4,6-dibutyl DBT. Therefore, Lysinibacillus sphaericus DMT-7 could serve as model system for efficient biodesulfurization of diesel and petrol. © 2011 The Research Centre for Eco-Environmental Sciences, Chinese Academy of Sciences.

Yellow Himalayan raspberry, a wild edible fruit, was analyzed for phenolic contents, and antioxidant, antibacterial and antiproliferative activities. Phenolics were extracted using 80 % aqueous solvents containing methanol, acidic methanol, acetone and acidic acetone. Our analysis revealed that the acidic acetone extracts recovered the highest level of total phenolics (899 mg GAE/100 g FW) and flavonoids (433.5 mg CE/100 g FW). Free radical scavenging activities (DPPH, ABTS, superoxide and linoleate hydroperoxide radicals) and ferric reducing activity were highest in the acetone and acidic acetone extracts. No metal chelating or antibacterial activity was detected in any of the extracts. Acetone and methanol extracts showed potent antiproliferative activity against human cervical cancer cells (C33A) with an EC50 of inhibition at 5.04 and 4. 9 mg/ml fruit concentration respectively, while showing no cytotoxicity to normal PBMCs cells. Therefore, the present study concluded that the yellow Himalayan raspberry is a potent source of phytochemicals having super antioxidant and potent antiproliferative activities. © 2012, Association of Food Scientists & Technologists (India).
