toxicity and oviposition deterrent activities of ethereal extracts of exocarp and kernel of ginkgo biloba seed were evaluated on various life stages of two spotted spider mite tetranychus urticae. petroleum ether was used for extraction. bioassay was conducted using three replicates for testing five concentrations 35, 45, 60, 75 and 100 g/l of pure extracts. lc50 was measured by pri-probit soft...

environmental friendly pesticides with a natural origin can be used as an alternative to chemicals in plant pests control programs. from this perspective, the extract of ginkgo biloba l. plant is important. in this study which was conducted in 2010, the ethereal extract of exocarp and kernel of g. biloba seed was analyzed using a gas chromatograph mass spectroscope. the components included gink...

Ginkgo biloba, the ginkgo tree, is the oldest living tree, with a long history of use in traditional Chinese medicine. In recent years, the leaf extracts have been widely sold as phytomedicine in Europe and as a dietary supplement worldwide. Effects of Ginkgo biloba extracts have been postulated to include improvement of memory, increased blood circulation, as well as beneficial effects to suff...

Ginkgo biloba was used as herbal remedy for many centuries in China, and now its extracts are one of the most widely used herbal products in the world, especially in the United States and in Europe [Blumenthal, 2000; Mahadevan & Park, 2008]. Gink...

Ginkgo biloba (Ginkgoaceae), originating from China, now distributes all over the world. Wide application of Ginkgo biloba extracts is determined by the main active substances, flavonoids and terpenoids, which indicates its extracts suitable to be used as an effective corrosion inhibitor. The extracts of Ginkgo biloba leave have been investigated on the corrosion inhibition of Q235A steel with ...

The present study investigated the effects of Ginkgo biloba extract and its flavonoid fractions on alpha-amylase and alpha-glucosidase activity in vitro. Ginkgo biloba extracts and their flavonoid fraction significantly inhibited alpha-amylase and alpha-glucosidase activity in vitro. Furthermore, Ginkgo biloba extracts and their flavonoid fraction reduced the elevation of rat plasma glucose lev...

Hot water extracts of Ginkgo biloba seeds were analyzed for the presence of ginkgotoxin (4'-O-methylpyridoxine) by reversed-phase liquid chromatography (LC) using methanol-0.05M KH2PO4 (1 + 9, v/v) adjusted to pH 3 as mobile phase. Detection was by fluorescence (excitation 280 nm, emission 370 nm). A straight line calibration curve was obtained for the 10-100 ng injected. After addition of beta...
