摘要

籽胶是一种由雌性昆虫Laccifer lacca Kerr在特定植物上分泌的有机树脂,其中一种是Kesambi (Schleicera oleosa Merr)。籽胶含有近80%的聚酯,可以水解成酯类化合物,如脂质酸,它是香水工业合成香料的中间化合物。天然染料(漆酸)的存在干扰了水解过程,影响了水解产物的纯度。在本研究中,首先通过去除紫胶的天然染料(脱色过程)来进行水解。采用气相色谱-质谱法对水解产物进行了表征,确定了酯的类型和组成。本实验对籽胶进行水解前的脱色处理,可使淀粉质酸的提取率提高到56%。因此,可以考虑先用脱色法水解,然后再水解,以籽胶为原料生产酯类

Characterization of Seedlac Hydrolysis from Kesambi (Schleicera oleosa Merr) as an Intermediate Compound for Fragrance Synthesis
Seedlac is the organic resin obtained from secretion of female insect Laccifer lacca Kerr on a selected plant, one of them is Kesambi (Schleicera oleosa Merr). Seedlac contains almost 80% polyester which can be hydrolysed to ester compounds such as aleuritic acid which is an intermediate compound for the fragrance synthesis of the perfume industry. One of the problems in the seedlac hydrolysis is the presence of natural dyes (laccaic acid) which interfered with the hydrolysis process and affect the purity of the hydrolysis products. In this research, hydrolysis was carried out by first removing the natural dyes of shellac (decolorized process). The hydrolysis results were characterized using Gas Chromatography-Mass Spectrometry to determine the type of ester and its composition. The decolorized process of seedlac before hydrolysis in this experiment could improve the percentage of aleuritic acid up to 56%. Therefore, seedlac hydrolysis by decolorized process before hydrolysis can be considered for the production of esters from seedlac, especially
