The fast atom bombardment (FAB) mass spectra and mass-selectedion kinetic energy spectra [MIKES] of sodium adduct ions [M+Na]~+ of six phenyl-propanoid glycosides have been studied. An intense sodium adduct appeared in their FABmass spectra, which was more abundant than the corresponding protonated molecular ion[M+H]~+ and may give more difinite information about molecular weight of the sample.The MIKES of these [M+Na]~+ ions provided a convenient way for sugar sequence anal-ysis of such glycosides....

研究了六种苯丙型苷与Na~+加合离子的快原子轰击质谱(FAB—MS)和质量分离离子动能谱(MIKES)。结果表明:在FAB谱中[M+Na]~+加合离子的丰度要比[M+H]~+离子高得多。由此可给出糖苷的分子量信息,[M+Na]~+离子的MIKES谱可给出糖基序列信息。

A new acyl sugar along with four know iridoidal and phenyl propanoid glycosides,harpagoside, harpagide,O-methyl catalpol and angoroside C,were isolated from the roots of Scrophularia ningpoensis Hemsl.,a famous traditional Chinese medicine known as″Xuan-Shem″. By means of chemical and spectral evidence its structure was elucidated as4-O-(p-methoxy cinnamoyl)-α-L-rhamnopyranose.

从中药玄参(ScrophularianingpoensisHemsl.)中分离得到1个新化合物:4-O-(对甲氧基肉桂酰基)-α-L-鼠李糖[4-O-(p-methoxycinnamoyl)-α-L-rhamnopyranose];同时还分离到4个已知的环烯醚萜甙:爪钧草甙(harpagide),爪钩草酯甙(harpagoside),O-甲基梓醇(O-methylcatalpol),士可玄参甙A(scropoliosideA)和1个已知的苯丙素甙:安格洛甙C(angorosideC)。新化合物的结构通过化学降解和光谱分析得到证明。

Using the MTT colorimetric assay,we studied antitumour effects of 6 phenyl-propanoid glycosides(PPG) from Pedicularis on three different tumour cell lines, The antitumoureffects of 6 PPG were related to their chemical structure,Their antitumour effects ranked asisoverbascoside, verbascoside,echinacoside, pedicularioside A >cistanoside D>permethyl verbas-coside.It was shown that the more number of phenolic hydroxyl groups,the stronger PPG’s anti-tumour effects.The phenolic hydroxyl groups were methoxylated,and...

采用抗癌药筛选新方法-MTT法,研究了6种从中草药马先蒿(Pedicularis)中分离提取的苯丙素甙化合物(phenylpropanoidglycosides,PPG)对3种不同组织癌细胞生长的抑制活性。结果表明:6种PPG的抗肿瘤活性强度与其化学结构密切相关;它们的抑癌活性强度顺序为:isoverbascoside,verbascoside,echinacoside,pediculariosideA>cistanosideD>permethylverbascoside;即分子中酚羟基越多,抗肿瘤活性愈强,当酚羟基完全被甲基化后,则对癌细胞生长无抑制作用。
