Abstract:
Object A study on the ingenol-type diterpene esters of Euphorbia kansui T. N. Liou ex T. P. Wang. Methods Their structures were elucidated by spectral analysis, especially 2DNMR ( 1H- 1HCOSY, HSQC, HMBC and NOESY). Results Six ingenol-type diterpene esters were isolated successfully, two of them were identified as 3-O-(2′E, 4′Z-decadienoyl)-20-O-acetylingenol (Ⅰ) and kansuiphorin C (Ⅱ). Conclusion NMR data of compound Ⅰ and 13 CNMR data of compound Ⅱ were first reported. On the basis of variety of 2DNMR experiments, NMR data of compound Ⅰ and Ⅱ were well assigned.
