摘要

根据植物化学分析,兰西植物不仅以萜类化合物为主要成分,还含有酚类物质。遗憾的是,有关这种植物酚类结构的信息仍然有限。本研究旨在从 Lansium domesticum 根的氯仿馏分中鉴定一种酚类结构。通过真空液相色谱法(VLC)和柱色谱法(CC)等色谱技术对氯仿馏分进行分馏和纯化,获得了一种香豆素。此外,还利用 1H-NMR 对香豆素的结构进行了表征。分离出的香豆素在 5%氯化铁的酚类测试中呈阳性结果。分离出的香豆素的 1H-NMR 光谱显示化学位移为 δH 7,60 (1H, d, J = 9,5 Hz)、6,92 (1H, s)、6,84 (1H, s)、6,27 (1H, d, J = 9,5 Hz)、6,14 (1H, s) 和 3,95 (3H, s)。根据这些结果以及与文献数据的比较,可以得出结论:分离出的香豆素是异香豆素 (1)

Karakterisasi Struktur Kumarin pada Akar Tumbuhan Langsat (Lansium domesticum Corr.)
Lansium plants produce not only terpenoids as the main constituent but also contain phenolics on the basis of phytochemical analysis. Unfortunately, there are still limited information about phenolic structures from this plants. This study was conducted to identify one of phenolic structures from chloroform fraction of Lansium domesticum root. The chloroform fraction was fractionated and purified by chromatographic techniques such as vacuum liquid chromatography (VLC) and column chromatography (CC) to obtain a coumarin. Additionally, the coumarin structure was characterized by 1H-NMR. The isolated coumarin showed a positive result for the phenolic test with FeCl3 5%. The 1H-NMR spectrum of isolated coumarin revealed chemical shifts at δH 7,60 (1H, d, J = 9,5 Hz), 6,92 (1H, s), 6,84 (1H, s), 6,27 (1H, d, J = 9,5 Hz), 6,14 (1H, s), and 3,95 (3H, s). Based on those results and comparison with literature data, it can be concluded that the isolated coumarin is iso-scopoletin (1)
