Antioxidant activity of Pueraria tuberose DC, (PT) Leguminosae (Fabaceae) has already been reported by us and here an active compound has been isolated and its action on expression of iNOS protein has been explored by using LPS induced changes in attached rat peritoneal macrophage cell culture. The
In the course of searching for new classes of α-glucosidase inhibitors originated from natural resources, 11 kinds of isoflavones, i.e., medicarpin (1), formononetin (2), mucronulatol (3), (3R)-calussequinone (5), (3R)-5'-methoxyvestitol (6), tectorigenin (7), biochanin A (8), tuberosin (9),
Changing life style and over-nutrition causes low-grade inflammation (LGI), with obesity and hyper-lipidemia as basic factors. The physiological state polarizes macrophages to classical type (M1), which is pro-inflammatory and promotes ectopic fat deposition in the body. Both factors induce
Pueraria tuberosa (Willd.) DC is a perennial herb commonly known as 'vidarikanda', distributed throughout south east Asia. The plant's tuber is widely used in ethanomedicine as well as in traditional systems of medicine, particularly in ayurveda. It has been used in various ayurvedic formulations as
A new isoflavone glycoside, (-)-tuberosin-3-O-β-D-glucopyranoside (1), along with 10 known compounds 1a-10, was isolated from Pueraria alopecuroides. Their structures were determined on the basis of spectral data including 1D and 2D NMR and HREIMS. These compounds were isolated from this plant for
One new flavone hydrate named lobatflavate (1), one new chromone named lobatchrosin (2), and one new isoflavone named 3S,4R-tuberosin (3), along with four known isoflavone analogues (4-7), were isolated from the traditional Chinese medicinal plant of Pueraria lobata (Willd.) ohwi. Their structures
Two isoflavone C-glucosides, puerarin (1) and PG-3 (2), a but-2-enolide, (+/-)-puerol B (3), two isoflavone O-glucosides, daidzin (4) and genistin (5), and three pterocarpans, (-)-medicarpin (6), (-)-glycinol (7) and (-)-tuberosin (8), were isolated from a MeOH extract of the roots of Pueraria
