广西肿节风药材有效成分含量与土壤因子关系研究

Study on relationship between soil factors and content of effective components in Sarcandra glabra in Guangxi

研究测定了广西区内18个肿节风主要分布区的土壤因子中化学性状和矿质元素含量与相应肿节风药材中的有效成分含量,并对之进行相关性分析,探讨了土壤因子对肿节风有效成分的影响,筛选出主导因子。结果显示,异嗪皮啶与有机质呈极显著正相关,与速效磷和速效钾呈显著正相关;迷迭香酸与速效磷呈显著正相关,速效氮、Ca对异嗪皮啶和迷迭香酸均呈显著负相关。研究表明土壤中丰富的有机质、速效磷和速效钾供应有利于提高药材中的有效成分含量。

This paper studied on the content of effective components in Sarcandra glabra and soil factors （including chemical properties and mineral elements） from 18 different counties in Guangxi, while the effects of soil factors on content of effective components were screened out and the leading factors were investigated through correlation analysis. It showed that isofraxidin had a highly significant positive correlation with organic matter, and had a significant positive correlation with available phosphorus and potassium. Rosmarinic acid had a significant positive correlation with available phosphorus. However, isofraxidin and rosmarinic both had significant negative correlation with effective nitrogen and mineral dement Ca. The result showed that abundant organic matter, available phosphorus and potassium in soil were all beneficial for the accumulation of isofraxidin and rosmarinic in plant.
