Abstract

Rubia tibetica Hook. f is a traditional Tibetan medicinal plant, with its roots serving as the primary medicinal part. Two new compounds, Rubiaxylm C and E (1 and 3), and one new natural compound, Rubiaxylm D (2) were isolated from R. tibetica, along with five known compounds (4-8). The structures of the previously undescribed compounds were elucidated by HR-ESIMS, 1D/2D NMR spectroscopic data and electronic circular dichroism calculations. Compound 1 is a rare anthrone substituted with a carbonyl group at position 1. Furthermore, all isolated compounds were tested for their cytotoxicity against HepG2 cell lines.

鉴定茜草根中的新化合物
西藏茜草(Rubia tibetica Hook. f)是一种传统的藏药用植物,其根部是主要的药用部分。从茜草中分离出了两种新化合物 Rubiaxylm C 和 E(1 和 3),一种新的天然化合物 Rubiaxylm D(2),以及五种已知化合物(4-8)。通过 HR-ESIMS、一维/二维核磁共振光谱数据和电子圆二色性计算,阐明了以前未曾描述过的化合物的结构。化合物 1 是一种罕见的在第 1 位被羰基取代的蒽酮。此外,还测试了所有分离化合物对 HepG2 细胞系的细胞毒性。
