从日本新香茶（Leucosceptrumjaponicum）全草中分离得到一个新的甾体苷（1）、一个新的苯丙素苷（2）和一个新的咖啡酸衍生物（3），以及八个已知的苯乙醇苷（4-11）、五个已知的黄酮苷（12-16）、三个已知的黄酮（17-19）、一个已知的苯丙素苷（20）、一个已知的环烯醚萜苷（21）、和八种其它酚类或吲哚化合物（22-29）。根据光谱分析结果，确定了这些化合物的结构和立体化学。
A new alkaloidal glycoside (1), a new phenylpropanoid glucoside (2), and a new caffeic acid derivative (3) were isolated from the whole plant ofLeucosceptrumjaponicum, together with eight known phenylethanoid glycosides (4–11), five known flavone glycosides (12–16), three known flavones (17–19), a known phenylpropanoid glucoside (20), a known iridoid glucoside (21), and eight other phenolic or indole compounds (22–29). The structures and stereochemistries of these compounds were elucidated on the basis of the results of spectroscopic analyses.
