Three iridoid glycosides 6-O-(3''-O-benzoyl)-alpha-L-rhamnopyranosylcatalpol (1a), 6-O-(3''-O-trans-cinnamoyl)-alpha-L-rhamnopyranosylcatalpol (2a) and 6-O-(3''-O-cis-cinnamoyl)-alpha-L-rhamnopyranosylcatalpol (3a) were isolated from aerial parts of Gmelina arborea and structures were elucidated by spectral analysis. Additionally a known iridoid 6-O-(3'', 4''-O-dibenzoyl)-alpha-L-rhamnopyranosylcatalpol (4) was also isolated and identified.
从海南石梓的地上部分分离得到三种环烯醚萜苷6-O-(3''-O-苯甲酰基)-α-L-鼠李吡喃糖基梓醇(1a)、6-O-(3''-O-反式肉桂酰基)-α-L-鼠李吡喃糖基梓醇(2a)和6-O-(3''-O-顺式肉桂酰基)-α-L-鼠李吡喃糖基梓醇(3a)，并通过光谱分析确定了其结构。此外，还分离鉴定了一种已知的环烯醚萜6-O-(3'',4''-O-二苯甲酰基)-α-L-鼠李吡喃糖基梓醇(4)。
