目的对不同来源竹黄中多糖的量进行分析比较,可为竹黄的开发利用提供借鉴。方法采用苯酚-硫酸法测定了不同生长时期、不同地点、不同寄主的16个竹黄样品中多糖量的变化。结果竹黄中多糖的量与单个竹黄含多糖的量均在5月上中旬达到最大;临近地点短穗竹上寄生的竹黄多糖的量以湿度较高采样点的较高;大多数不同采样点短穗竹上寄生的竹黄中多糖的量有极显著差异,单个子座中的竹黄多糖与竹红菌甲素的量没有显著相关性。结论 5月上中旬是竹黄采收的最佳季节。
Objective To analyze and compare the amount of polysaccharides in different origins of bamboo, which may provide reference for the development and utilization of bamboo. Methods The changes of polysaccharides in 16 samples of bamboos were determined by phenol-sulfuric acid method at different growth stages, different locations and different hosts. The results showed that the amount of polysaccharides and the content of polysaccharides in bamboo rhizome reached the maximum in the middle of May, while the amount of bamboo polysaccharides parasitized in the adjacent spots was higher at the higher humidity sampling points. Most of them were different There was a significant difference in the amount of polysaccharide in the bamboo parasitic on the short-spike bamboo of the sampling point. There was no significant correlation between the amount of the bamboo-yellow polysaccharide in the individual sub-bases and the amount of the macropinothiazin A. Conclusion The best mid-May harvest of bamboo is the best harvest season.
