The phytochemical investigation of the n-butanol soluble fraction of the bark of stem of Symplocos racemosa Roxb. yielded two new phenolic glycosides of salirepin series, symplocuronic acid (1) and sympocemoside (2), while salirepin (3) was isolated for the first time from this plant. The structures of the new compounds were identified by 1D and 2D NMR techniques along with other spectral evidences and by comparison with the published data of closely related compounds.
对山矾科植物华山矾茎皮正丁醇可溶部分进行的植物化学研究,得到了两个新的水龙骨萜醇系列酚苷,即华山矾酸(1)和华山矾苷(2),而水龙骨萜醇(3)首次从该植物中分离得到。通过一维和二维核磁共振技术以及其他光谱证据,并与密切相关化合物的已发表数据进行比较,确定了新化合物的结构。
