Phytochemical and biological screening of root of Asparagus racemosus was studied. The brine shrimp bioassay of its various extracts showed that the methanol (MeOH) extract was biologically active. The column chromatography of hexane, acetone and methanol extracts resulted in the isolation of 9hexadecanoic acid-9-octadecenylester (Z,Z), β-Sitosterol, stigmasterol-3-O-β-D-glucopyranoside and dio...

Antifungal constituents, 2-isopropenyl-4-methyl-1-oxa-cyclopenta[b]anthracene-5,10-dione and (+)-4-(2'-hydroxy-3'-methylbut-3'-enyloxy)-8H-[1,3]dioxolo[4,5-h]chromen-8-one in addition to known compounds imperatorin, beta-sitosterol, plumbagin, 1-methyl-2-(3'-methyl-but-2'-enyloxy)-anthraquinone, beta-sitosterol glucoside, stigmasterol, vanillin and salicin were isolated during phytochemical inv...

Phytochemical screening of various fractions of Datura alba showed bioactive secondary metabolites based on microbial and antioxidant activities. n-Hexane fraction showed a significant activity against three selected bacterial strains; Bacillus subtilis, Klebsiella pneumoniae and Staphylococcus aureus while other isolated fraction showed moderate activity. The ethyl acetate (88.89 %) and methan...

In the present study, Radix Codonopsis was extracted by supercritical CO2 extraction. As Ointment collecting rate and the yield of stigmasterol are index, Various reaction parameters were changed to attain the optimal conditions. The appropriate process conditions are size 40 60Mesh, 30 Mpa pressure, temperature 65 °C, 120 min, entrainer Alcohol dynamic extraction (entrainer pump flow rate of 1...
