Abstract

The present sterol quantitation was carried out for four Setaria plants by gas chromatography. In S. italica, sitosterol was most abundant in all components and sitostanol accumulated in the seeds much more than other tissues. Stigmasterol accumulation was limited to leaves and stems. Sterol content of S. viridis, S. X pycnocoma and S. glauca were determined. Sitostanol was found present in these plants in less amounts than in S. italica. Major phytosterol content (campesterol, stigmasterol and sitosterol) of S. X pycnocoma was essentially the same as that of S. italica, while S. viridis and S. glauca content differed considerably from S. italica, major sterol content in leaves and stems being much less compared to seeds. These differences in the four Setaria plants are of interest from a chemotaxonomical standpoint.
气相色谱法测定某些狗尾草属植物中甾醇的含量
采用气相色谱法对四种尾草属植物进行甾醇含量测定。在意大利葡萄各成分中,谷甾醇含量最高,且谷甾醇在种子中的积累量远大于其他组织。豆甾醇的积累仅限于叶和茎。测定了绿葡萄球菌、青光眼葡萄球菌和青光眼葡萄的甾醇含量。在这些植物中发现谷甾醇的含量低于意大利葡萄。其主要植物甾醇(油菜甾醇、豆甾醇和谷甾醇)含量与意大利葡萄基本相同,而绿葡萄和青花葡萄与意大利葡萄含量差异较大,叶片和茎中的主要甾醇含量远低于种子。从化学分类学的角度来看,四种尾草属植物的这些差异是有趣的。
