Six new highly oxygenated eremophilane-type sesquiterpene derivatives (1-6), including a norbisesquiterpene, were isolated from an extract of the roots of Ligularia lapathifolia, and their structures were elucidated by spectroscopic methods. The structure of 1 was confirmed by single-crystal X-ray crystallography. In addition, the cytotoxicity of compounds 1, 2, 3, 5, and 6 was evaluated against selected cancer cell lines, including human stomach carcinoma (MGC-803), human hepatoma (HEP-G2), and murine sarcoma (S-180) cell lines.
从宽叶橐吾根部提取物中分离出6种新的高氧化桉叶烷型倍半萜衍生物(1-6),包括一种降倍半萜,并用光谱方法阐明了它们的结构。通过单晶X射线晶体学确定了1的结构。此外,还评估了化合物1、2、3、5和6对选定癌细胞系的细胞毒性,包括人胃癌(MGC-803)、人肝癌(HEP-G2)和小鼠肉瘤(S-180)细胞系。
