Abstract

Phytochemical investigation of the leaves of Sorindeia juglandifolia A. Rich. led to the isolation and identification of a new C-glucosylflavone, 2",6"-di-O-acetyl-7-O-methyl vitexin (1), together with seven known compounds, 2"-O-acetyl-7-O-methyl vitexin (2), mearnsitrin (3), robustaflavone (4), 3-O-galloyl catechin (5), tachioside (2-methoxy-benzene-1,4-diol-1-O-beta-glucopyranoside) (6), 3beta-O-D-glucopyranosyl-beta-stigmasterol (7), and methyl gallate (8). The structures of 1 and the known compounds were established by IR, UV, MS, 1D, and 2D NMR spectra and by comparison with those of related compounds.

摘要

对 Sorindeia juglandifolia A. Rich. 的叶进行的植物化学研究导致分离和鉴定出一个新的 C-葡萄糖基黄酮，2",6"-二-O-乙酰基-7-O-甲基牡荆素（1），以及七个已知化合物，2"-O-乙酰基-7-O-甲基牡荆素（2），mearnsitrin（3），robustaflavone（4），3-O-没食子酰儿茶素（5），tachioside（2-甲氧基-苯-1,4-二醇-1-O-β-葡萄糖苷）（6），3β-O-D-葡萄糖基-β-豆甾醇（7）和没食子酸甲酯（8）。1 和已知化合物的结构通过 IR、UV、MS、1D 和 2D NMR 光谱以及与相关化合物的比较来确定。
