Bioassay-guided isolation and identification of antifungal compounds from ginger.
A bioassay-guided isolation of antifungal compounds from an African land race of ginger, Zingiber officinale Roscoe, led to the identification of [6], [8] and [10]-gingerols and [6]-gingerdiol as the main antifungal principles. The compounds were active against 13 human pathogens at concentrations of <1 mg/mL. The gingerol content of the African land race was at least 3 x higher than that of ty...
متن کاملRapid Bioassay-Guided Isolation of Antibacterial Clerodane Type Diterpenoid from Dodonaea viscosa (L.) Jaeq.
Plant extracts are complex matrices and, although crude extracts are widely in use, purified compounds are pivotal in drug discovery. This study describes the application of automated preparative-HPLC combined with a rapid off-line bacterial bioassay, using reduction of a tetrazolium salt as an indicator of bacterial metabolism. This approach enabled the identification of fractions from Dodonae...
متن کاملAntioxidant Activity of Two Flavonol Glycosides from Cirsium Hypoleucum Dc. through Bioassay- Guided Fractionation
The flowers, roots and stems of Cirsium species are used as a folk remedy in Anatolia. In order to evaluate antioxidant activity of Cirsium hypoleucum which is an endemic plant, superoxide radical (hypoxanthine-xanthine oxidase system) and free radical scavenging activities (DPPH) using in vitro electron spin resonance (ESR) spectrometry of the different extracts, fractions and compounds obtain...
متن کاملApoptosis-inducing activity of compounds screened and characterized from cinobufacini by bioassay-guided isolation.
Cinobufacini (huachansu), an aqueous extract from the skin of the toad Bufo bufo gargarizans Cantor, is a traditional Chinese medicinal preparation widely used in clinical cancer therapy in China. Here, we screened and identified active compounds of cinobufacini and investigated their apoptosis-inducing effect on HepG2 cells. Screening was performed using bioassay-guided isolation. The effects ...
متن کاملBioassay-guided isolation and identification of cytotoxic compounds from Gymnosperma glutinosum leaves.
Bioassay-guided fractionation of hexane extracts of Gymnosperma glutinosum (Asteraceae) leaves, collected in North Mexico, afforded the known compounds hentriacontane (1) and (+)-13S,14R,15-trihydroxy-ent-labd-7-ene (2), as well as the new ent-labdane diterpene (-)-13S,14R,15-trihydroxy-7-oxo-ent-labd-8(9)-ene (3). In addition, D-glycero-D-galactoheptitol (4) was isolated from the methanolic ex...
