Two new ent-labdane diterpenoid glycosides were isolated from the aerial parts of Andrographis paniculata. Their structures were elucidated as 3-O-beta-D-glucosyl-14-deoxyandrographiside (1) and 3-O-beta-D-glucosyl-14-deoxy-11,12-didehydroandrographiside (2) by means of 1D and 2D NMR spectral and chemical methods.
从穿心莲地上部分分离得到两个新的对映-贝壳杉烷二萜糖苷。通过一维和二维核磁共振光谱及化学方法确定它们的结构分别为3-O-β-D-葡萄糖基-14-脱氧穿心莲内酯（1）和3-O-β-D-葡萄糖基-14-脱氧-11,12-二脱氢穿心莲内酯（2）。
