A new phenolic glycoside, 7-(4-O-β-D-glucopyranosyl, 3-methoxyphenyl)-6,8-dihydrofuro[3′,4′:7,8]naphtho[1,2-d][1,3]dioxol-10(7H)-one, named malconenoside A (1), was isolated from Bupleurum malconense Shan et Y. Li. The structure, including absolute configurations, was assigned by using spectroscopic methods and ECD calculation. Biological activities of compound 1 towards human cancer cells (HepG2, BGC-823, and A549) were evaluated. The most sensitive two cell lines were HepG2 and BGC823, in which the IC₅₀ values of compound 1 were 8.70 and 16.94 μM, respectively.

一种新的酚糖苷，7-(4 - O - β -D-吡喃葡萄糖基，3-甲氧基苯基)-6,8-二氢呋喃[3',4':7,8]萘并[1,2-d][1, 3]dioxol-10(7H)-one，命名为malconenoside A ( 1 )，是从Bupleurum malconense Shan et Y. Li 中分离出来的。通过使用光谱方法和 ECD 计算分配结构，包括绝对构型。评估了化合物1对人类癌细胞（HepG2、BGC-823 和 A549）的生物活性。最敏感的两个细胞系是 HepG2 和 BGC823，其中化合物1的 IC ₅₀值分别为 8.70 和 16.94 μM。
