摘要: 从毛姜花(Hedychium villosum Wall.)中分离得到1个新二萜(1)和1个已知二萜(3). 新二萜命名为Villosumcoronarin, 该化合物在氯仿或甲醇溶液中发生异构化, 部分转化为其差向异构体1'; 其平面结构经质谱、红外光谱、氢谱、碳谱及无畸变极化转移增强技术(DEPT)、氢氢相关谱(1H-1H COSY)和异核多键相关谱(HMBC)等方法确证; 其相对构型由氢谱、ROESY及量化计算确证. 化合物3用琼斯试剂氧化后得到化合物4. 生物活性筛选结果表明, 化合物1对人白血病细胞株(HL-60)和肝癌细胞株(SMMC-7721)具有强的细胞毒活性, 其活性超过阳性对照顺铂(DDP). 化合物4对HL-60和SMMC-7721细胞具有显著的细胞毒活性.

Abstract: Research on active components from rhizomes of Hedychium genus has led to isolation of some diterpenes with significant cytotoxic activities against Chinese hamster V-79 cells, KB cells, K562 cells, A549 cells, etc.. Hedychium villosum Wall. is a perennial rhizomatous herb distributed in China and partially in Southeast Asia, which is used in the treatment of pain and inflammation. A new labdane-type diterpene(1), together with a known one(3), were isolated from Hedychium villosum. The new diterpene was named as villosumcoronarin, which partially isomerized to its epimer 1' in solution, e.g., chloroform or methanol. The gross structures of compounds 1 and 1' were elucidated on the basis of MS, IR, 1H NMR, 13C-DEPT NMR, 1H-1H COSY and HMBC. The relative configuration was determined by 1H NMR, ROESY and computational methods. Compound 1 was identified as(11S, 15R)-11-hydroxy-8(17), 12(E)-labdadien-15,16-dial 11,15-hemiacetal. The known compound 1 was oxidized by Jones reagent to get diterpene derivative 1. Bioassays revealed that compound 1 had strong cytotoxic activity against HL-60 and SMMC-7721 cells with IC50 values of 0.74 and 4.48 μmol/L, respectively, the activities were stronger than the positive control, cis-diaminedichloroplatinum(DDP). Compound 1 also showed significant activities against HL-60 and SMMC-7721 cells with IC50 values of 3.15 and 9.57 mmol/L, respectively.
