Isolation and identification of chemical constituents from Sabia parviflora (II) / 中草药

ABSTRACT

Objective: To study the chemical constituents from Sabia parviflora. Methods: Various column chromatographic techniques were used to separate and purify the chemical constituents which structures were elucidated by spectral analysis. Results: Fifteen compounds were isolated and identified as 1,3,5-trimethoxybenzene (1), vanillic aldehyde 4-O-β-D-glucopyranoside (2), 2,6-dimethoxy-4-hydroxybenzyl alcohol 1-O-β-D-glucopyranoside (3), rel-5-(3S,8S-dihydroxy-1R,5S-dimethyl-7-oxa-6-oxobicyclo [3,2,1]-oct-8-yl)-3-methyl-2Z,4E-penta-dienoic acid (4), protocatechuic acid (5), 4-quinolinone-2-caboxylic acid (6), 3,4,5-trimethoxy benzoic acid (7), pyrocatechol (8), syringic acid-4-O-β-D-glucopyranoside (9), (-)-(7α,8S)-erythro-1-C-syringylglycerol 4-O-β-D- glucopyranoside (10), 3,4,5-trimethoxy benzoic acid (11), 1,2,4-trihydroxybenzene (12), ferulic acid (13), vanillic acid (14), and p-hydroxybenzoic acid (15). Conclusion: Compounds 1-11 are isolated from the genus of Sabia for the first time, and compounds 12-15 are isolated from this plant for the first time.
