对不同种竹叶样品,分别用硝酸铝-亚硝酸钠比色法和福林试剂还原比色法测定总黄酮和总酚含量,用蒽酮-硫酸法测定总糖及水溶性糖成分的含量,用凯氏定氮法测定含氮量和蛋白质含量.结果表明,不同竹叶中总黄酮含量1.18%～2.02%,总酚含量2.21%～2.86%,总糖含量14.35%～24.61%,水溶性糖含量7.86%～11.45%,多糖6.49%～14.55%,蛋白质含量10.24%～16.68%,含氮量2.13%～2.65%.采用滤纸片法进行抗菌试验,结果表明,不同竹种及不同生长期的竹叶抗菌活性不同,麻竹叶的抗菌活性强于其他竹叶,7月和11月中旬采摘的竹叶的乙醇提取液的抗菌活性较高.

With different kinds of bamboo leaves, content of flavonoids and total phenolic compounds measured by aluminium nitrate-sodium nitrite colorimetry and forint reagent deoxidization colorimetry were 1.18%～2.02% and 2.21%～2.86% respectively. Contents of total sugar, water-soluble sugar and polysaccharides measured by anthranone-sulphuric acid method, were 14.35%～24.61%, 7.86%～11.45% and 6.49%～14.55% respectively. The nitrogen content and protein content measured by Kjeldahl method were 2.13%～2.65% and 10.24%～16.68% respectively. Antimicrobi...
