[Abstract]
Object To study the chemical constituents of a new species belonging to genus Tinospora (Menispermaceae)—the Tinospora hainanensis H. S. Lo et Z. X. Li. Methods Isolation and purification were carried out on silica gel column, identified by physico-chemical properties and structurally elucidated by spectral analysis.Results 4 non-alkaloids were obtained. They were 24-epi-makisterone A (Ⅰ),octacosanoic acid (Ⅱ), octacosyl alcohol (Ⅲ) and hexacosyl alcohol (Ⅳ). Conclusion All of the 4 compounds were obtained from this plant for the first time, and compounds?Ⅰ,Ⅱ?and?Ⅳ?were obtained from genus Tinospora for the first time.
