目的 分离鉴定蓝萼香茶菜化学成分。方法 95%乙醇提取,硅胶及ODS柱层析分离,IR，NMR，MS方法确定结构。结果 分得5个化合物Ⅰ～Ⅴ分别鉴定为蓝萼甲素(glaucocalyxin A)、蓝萼乙素(glaucocalyxin B)、蓝萼丁素(glaucocalyxin D)、胡萝卜苷(daucosterol)、芦丁(rutin)。结论 分得的5个化合物中芦丁和胡萝卜苷为首次从该植物中分离得到。

OBJECTIVE To isolate and elucidate the chemical constituents from Rabdosia japonica. METHODS Chromatography on silica gel and ODS was used.The structures were determinde by IR,1H-NMR,13C-NMR and MS spectral analysis. RESULTS Five constituents(I～Ⅴ) were elucidated as glaucocalyxin A,glaucocalyxin B,glaucocalyxin D,rutin,daucosterol,respectively. CONCLUSION Rutin and daucosterol were isolated from this plant for the first time.
