One new compound, crocusatin M (1), and three new glycosidic compounds, crocusatins N-P (2–4), along with nine known compounds were isolated from the dried stigmas of Crocus sativus. The structures of new compounds were elucidated on the basis of spectroscopic analysis, and the absolute configurations of 1, 2, and 3 were unambiguously assigned by the comparison of experimental and calculated ECD data
一种新化合物 crocusatin M ( 1 ) 和三种新糖苷化合物 crocusatins NP ( 2-4 ) 以及九种已知化合物从番红花的干燥柱头中分离出来。在光谱分析的基础上阐明了新化合物的结构,并通过比较实验和计算的 ECD 数据明确指定了1、2和3的绝对构型。这是从番红花属中分离出具有 HMG 部分的4的首次报道。化合物1和4对抑制脂多糖(LPS)诱导的NO产生表现出较弱的抗炎活性。 图形摘要
