Coumarins are lactones with 1,2-benzopyrone basic structure, and are widely distributed in the plant kingdom, both in free form, and in glycosylated form. This work reports a literature review, describing the data of 13C NMR from 53 coumarins isolated from the family Moraceae, and data comparison between genera who presented photochemical studies, in order to contribute to the chemotaxonomy of this family.展开更多
文摘泰山前胡(Peucedanum wawrii(Wolff)su.)为多年生草本,有镇咳,祛痰的功效有较多蕴藏量,但尚未加以利用现报道泰山前胡香豆素的研究结果。结晶 A,熔点138—140℃,分子式为 C_(24)H_(28)O_7,红外光谱提示有酯基、芳环、芳醚。质谱 m/z:M^+428,核磁共振谱示有凯林(khellactone)母核,连结异戊草酸及当归酸。此结晶不溶于水,能溶于无水乙醇及氯仿等溶剂。经鉴定结晶 A 为白花前胡 E 素(3′-angeloyl-4′-isovaleryl-cis-khellactone)。
