Two new tricyclic trans-clerodane diterpenoids trivially named as ballotenic acid A (1) and ballodiolic acid A (2) have been isolated from ethyl acetate fraction of Otostegia limbata. The structure assignments are based on (1)H and (13)C NMR spectra, 2D NMR (HMQC, HMBC, COSY, NOESY and NOE) techniques and comparison with the literature data.
从绵毛齿叶草的乙酸乙酯馏分中分离出两种新的三环反式克罗烷二萜类化合物,通俗地命名为巴洛替酸A(1)和巴洛二醇酸A(2)。结构归属基于氢核磁共振(¹H NMR)和碳核磁共振(¹³C NMR)光谱、二维核磁共振(HMQC、HMBC、COSY、NOESY和NOE)技术以及与文献数据的比较。
