番石榴叶新颖杂萜醛类波谱学特征

Spectroscopic characteristics of novel Psidium meroterpenoids isolated from guava leaves

新奇杂萜醛类化合物独存在番石榴叶中,论文归纳其波谱学特征与生源途径,对文献波谱数据进行综合整理分析。综述结果表明杂萜醛类波谱学特征鲜明,文献杂萜醛位序编号不一致,具有合理生源途径,是番石榴叶的特征化学成分。

Recently, novel Psidium meroterpenoids were reported in the guava leaves. According to careful analysis of the spectral data of literatures, the spectroscopic characteristics and biosynthetic pathway of Psidium meroterpenoids were summarized in this paper. The results showed that Psidium meroterpenoids had distinct spectroscopic features and reasonable biosynthetic routines, however the number order of carbon atoms was not consistent in the reported literatures. It was concluded that Psidium meroterpenoids were the characteristic chemical constituents of Psidium guajava Linn.
