黄杆乌哺鸡竹主要化学成分的研究

The Chemical Composition of Phyllostachys vivax f. aureocaulis

通过实验揭示黄秆乌哺鸡竹化学成分在不同的时期的规律变化:(1)笋壳及笋的1%氢氧化钠抽出物及灰分在整个生长周期是最高的;(2)综纤维和硝酸乙醇纤维及苯醇抽出物总体上来说是逐年积累的而1%氢氧化钠抽出物和热水抽出物及灰分是逐年下降的;(3)同一年龄的不同部位的各种含量并没有呈现出很明显的差异分布。

This experiment aims to reveal the changes in the chemical composition of Phyllostachys vivax f.aureocaulis at different development stage.The results showed that the contents of 1％ NaOH extractive and ash of bamboo shoots and shells were the highest in the whole growth period.The contents of holocellulose,Nitric-acid and alcohol cellulose increased year by year,while that of alkali extractive,hot water extractive and ash decreased yearly.The chemical compositions in different bamboo parts were not significantly different.
