Abstract

The chemical structure of fatty acid compounds in plant parts other than seeds and fruit is still not widely known even though it has various benefits. One of the plants known to contain fatty acid compounds is Langsat. This research was conducted to characterize the structure of fatty acid compounds and the content of secondary metabolites in the roots of the langsat plant. The fatty acid characterization process was carried out by spectroscopy while the secondary metabolite content was analyzed by phytochemical screening test. Based on the spectrum of Proton Nuclear Magnetic Resonance (H-NMR) in acetone-d6 solvent at a frequency of 500 MHz, chemical shift data were obtained at 0.89 ppm (t, 3H), 1.33 ppm (m, 6H), 1.63 ppm (m, 2H), 2.33 ppm (t, 2H) and 8.14 ppm (s, 1H) and the results of phytochemical tests on the methanol extract of langsat root are known to contain alkaloids, terpenoids, flavonoids, phenolics, and saponins. Based on these data and compared with the literature, it is suspected that L1 isolates have similarities with the structure of compounds belonging to the fatty acid group.
除种子和果实外,植物其他部位的脂肪酸化合物的化学结构仍不为人所知,尽管它有各种好处。一种已知含有脂肪酸化合物的植物是龙舌兰。本研究旨在表征龙舌兰根中脂肪酸化合物的结构和次生代谢物的含量。通过光谱法对脂肪酸进行表征,通过植物化学筛选试验对次生代谢物含量进行分析。基于500 MHz丙酮-d6溶剂中质子核磁共振(H-NMR)谱,得到了在0.89 ppm (t, 3H)、1.33 ppm (m, 6H)、1.63 ppm (m, 2H)、2.33 ppm (t, 2H)和8.14 ppm (s, 1H)下的化学位移数据,并对龙参根甲醇提取物进行了植物化学测试,发现其含有生物碱、萜类、黄酮类、酚类和皂苷。根据这些数据并与文献进行比较,我们怀疑L1分离物与属于脂肪酸基团的化合物具有相似的结构。
