A phytochemical study focusing on the secoiridoid components in the fruits of Ligustrum lucidum was carried out, which finally led to the isolation of nine secoiridoid glycosides (1-9) together with two secoiridoids (10, 11). The structures of all compounds were established mainly by NMR and MS experiments as well as the necessary chemical evidence, of which 1, 2, 4 (ligulucisides A-C), 10 and 11 (liguluciridoids A and B) were identified as new secoiridoid analogues. An in vitro antiviral bioassay indicated that 1, 4, 6, and 10 displayed the inhibitory activities against influenza A virus with the IC values of 16.5, 12.5, 13.1, and 18.5 μM, respectively, which were better than the positive control Ribavirin (IC 22.6 μM). .
对女贞果实中的裂环环烯醚萜类成分进行了植物化学研究，最终分离出9种裂环环烯醚萜苷（1 - 9）以及2种裂环环烯醚萜（10、11）。所有化合物的结构主要通过核磁共振（NMR）和质谱（MS）实验以及必要的化学证据得以确定，其中1、2、4（女贞苷A - C）、10和11（女贞裂环环烯醚萜A和B）被鉴定为新的裂环环烯醚萜类似物。体外抗病毒生物测定表明，1、4、6和10对甲型流感病毒具有抑制活性，其半数抑制浓度（IC）值分别为16.5、12.5、13.1和18.5 μM，优于阳性对照利巴韦林（IC 22.6 μM）。
