Biological effects, antioxidant and anticancer activities of marigold and basil essential oils
The essential oils isolated from Tagetes minuta L. flowers and Ocimum basilicum L. herb were analyzed by GC/MS and assessed for antioxidant and in vitro and in vivo anticancer activities. Also biological effects of these essential oils on normal mice were studied. The major components of marigold essential oil were cis-β-ocimene (54.82%), cis-tagetone (11.50%) and...

Antimicrobial activity and phytochemical screening of aqueous and ethanol extracts of Momordica charantia L. leaves
The aim of the present study was to investigate the antimicrobial activity and to carryout phytochemical screening of aqueous and ethanol extracts of the leaves of Momordica charantia L. The result of the phytochemical screening revealed the presence of alkaloids, tannins, saponins, flavonoids and cardiac glycosides. However, the antimicrobial activity was investigated by agar-well diffusion method...

Potential allelopathic effects of Xanthium italicum Moretti on wheat
The allelopathic potential of invasive Xanthium italicum Moretti on seedling growth of wheat (Triticum aestivum Linn) was investigated. Aqueous (0.05 g/ml) and ethanol (1 mg/ml) extracts reduced root elongation of wheat seedlings by 71 and 87%, respectively; chloroform fraction of the ethanol extract exhibited the strongest phytotoxic effect as compared to other fractions, inhibiting root growth of wheat...

Medicinal plants used in the treatment of livestock diseases in Vhembe region, Limpopo province, South Africa
Traditional medicine (TM) is very important among Venda speaking people but the available literature does not cover the ethnoveterinary medicine (EVM) uses. Open ended questions and group focus discussion were used to investigate the knowledge of EVM in the region. Thirty-seven (37) individuals with an average age of 48.2 years were interviewed of which 24 were males and 13 females. EVM practices involved the use of...

Modeling of convective drying of safed musli (Chlorophytum borivilinum)
The drying kinetics of Safed musli (Chlorophytum borivilinum) in terms of moisture content, moisture ratio, drying time and drying rate was investigated. A laboratory model dehumidified air dryer and a hot air dryer (Tray dryer) were employed to study the drying behavior at 30, 35, 40 and 45°C. Safed musli drying primarily occurred in falling rate period. The drying data were fitted to seven thin layer drying models...

Protective effect of extracts of calyx from Diospyros kaki on H2O2-induced cytotoxicity in PC12 cells
Oxidative stress is considered a major cause of cellular injuries, including various clinical abnormalities. Here, the neuroprotective effect of extracts from the calyx of Diospyros kaki(DCE), peel of D. kaki (DPE), and flesh of D. kaki (DFE) of Diospyros kaki on oxidative stress-induced apoptosis in PC12 cells was investigated by an 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyl...
