Wang, Ping published the artcilePhenylpropanoids and diphenylethene compounds from roots and rhizomes of Smilax scobinicaulis, Recommanded Product: 5-(6-Hydroxybenzofuran-2-yl)benzene-1,3-diol, the publication is Zhongguo Zhongyao Zazhi (2013), 38(10), 1531-1535, database is CAplus and MEDLINE.
The chem. constituents were separated and purified from the roots and rhizomes of Smilax scobinicaulis by various chromatog. methods including silica gel, Sephadex LH-20. Their structures were obtained and identified as resveratrol-3-O-β-D-glucopyranosyl-(1->3)-β-D-glucopyranoside(1), resveratrol(2), δ-viniferin(3), Et caffeate(4), 1-O-caffeoyl glycerol(5), 1-O-p-coumaroyl glycerol(6), 1-O-feruloyl glycerol(7), grossamide(8), moracin M(9) on the anal. of spectroscopic data. Compound 1 was a new compound and compounds 3-5, 8, 9 were separated from this plant for the first time.
Zhongguo Zhongyao Zazhi published new progress about 56317-21-6. 56317-21-6 belongs to benzofurans, auxiliary class Metabolic Enzyme,PDE,Natural product, name is 5-(6-Hydroxybenzofuran-2-yl)benzene-1,3-diol, and the molecular formula is C9H8O4, Recommanded Product: 5-(6-Hydroxybenzofuran-2-yl)benzene-1,3-diol.
