采用化学定量分析方法,对龙牙楤木俗名刺嫩芽叶绿素的性质进行了研究,研究结果表明刺嫩芽叶绿素总含量为0.3691mg/g。叶绿素对光、热、酸性介质均不稳定,易产生降解现象;在散射光环境中,降解速度随时间延长和温度升高而加快;在pH值6～7时的中性条件下最稳定,在pH值3～4的酸性条件下,叶绿素易降解。
The chemical constituents of Aralia elata were studied by means of chemical quantitative analysis. The results showed that the total content of chlorophyll in thorns was 0.3691 mg / g. Chlorophyll is unstable to light, heat and acidic medium, and it is easy to produce degradation. Under the condition of scattered light, the degradation rate increases with time and temperature. Under the neutral condition of pH 6 ~ 7, Under pH 3 ~ 4 acidic conditions, chlorophyll is easy to degrade.
