摘要
以没食子酸为对照品,采用Folin-ciocalteu比色法测定青海3种特色植物沙棘(Hippohae rhamnoides)、青海云杉(Picea crassifolia)、祁连圆柏(Sabina przewalskii)的根、茎、叶总多酚,并分析同一植物不同部位及不同植物同一部位的总多酚。结果表明,祁连圆柏叶总多酚含量最高;同一植物不同部位总多酚含量均差异显著;不同植物同一部位除沙棘与青海云杉叶总多酚差异不显著外,其他均差异显著。
Taking gallic acid as control sample, the content of total polyphenol in different organs of Hippohae rhamnoides,Picea crassifolia and Sabina przewalskii in Qinghai province were measured by Folin-Ciocalteu colorimetry. The content of total polyphenol in different parts of same plant species and same part of different plant species were analyzed. The results showed that total polyphenol content in leaf of Sabina przewalskii was highest. Total polyphenol content in either two parts from the same plant species was significantly different. Total polyphenol content between the same part of different plant species was significantly different except for those of the leaf of Hippohae rhamnoides and Picea crassifolia.
