摘要：采用皮粉法和高效液相色谱法分别测定了我国五倍子主产区14个产地角倍的单宁酸和没食子酸含量,分析角倍单宁酸和没食子酸含量与倍子性状及环境因子间的相关性。结果表明:14个产地角倍的单宁酸含量为61.59%68.30%,平均含量64.49%;没食子酸含量为70.35%77.61%,平均含量73.92%;倍壁厚度为1.552.01 mm,倍子密度为0.16 0.33 g.mL-1。方差分析表明不同产地角倍的单宁酸含量、没食子酸含量、倍壁厚度和倍子密度差异显著。相关分析结果:单宁酸含量与没食子酸含量呈显著正相关,单宁酸和没食子酸含量分别与4—8月的月均温呈显著负相关,而与倍壁厚度、倍子密度及经纬度、海拔、湿度等环境因子相关性不显著,表明温度是影响倍子质量的主要环境因子。聚类分析将14个产地的角倍分为3类,分别代表了优良、中等和一般的类群。
The contents of tannin and gallic acid of 14 Chinese gallnut samples from different producing areas were determined by hide powder method and high performance liquid chromatography,respectively.The results showed that the tannin contents ranged from 61.59% to 68.30% and the mean content was 64.49%.Gallic acid content ranged from 70.35% to 77.61% and the mean content was 73.92%.The wall thickness of galls ranged from 1.55 to 2.01 mm,and density ranged from 0.16 to 0.33 g·mL-1.Correlation analysis indicated that the tannin contents had a positive significant correlation with the gallic acid contents,but the tannin and gallic acid contents had no significant correlations with the wall thickness and density,respectively.Meanwhile,both of the tannin and gallic acid content had a negative significant correlation with mean month temperatures of April to August and had no significant correlations with the relative humidity,precipitation,and sunshine duration respectively.It is suggested that temperature was an important factor affecting the quality of Chinese gallnut.The cluster analysis showed that 14 Chinese gallnut samples could be divided into 3 quality groups which stood for excellent,moderate and common categories.
