Isolation and structure elucidation of two new cassane derivatives from the seed kernels of Caesalpinia sinensisLian Lian, Ye Yang, Dan-Dan Guo, Yan-Fang Yan, Hui-Yuan Gao, Xian-Zhe Li & Miao Wang
Two new cassane-type derivatives (1–2), together with three known compounds (3–5), were isolated from the seed kernels of Caesalpinia sinensis. Their structures were elucidated on the basis of interpretation of comprehensive spectroscopic data, including HRESIMS and 1D/2D NMR spectroscopy, and the absolute configuration were established by means of ECD calculation. Compound 2, possessing a 16-degradative cassane skeleton, was rarely encountered in cassane diterpenoids isolated from the genus Caesalpinia. All compounds were evaluated for their anti-inflammatory...
