丹参品质与主导气候因子的灰色关联度分析

气候因子对丹参(Salvia miltiorrhiza Bunge)生长及有效成分含量有重要影响,为科学选择人工种植基地,需要明确影响丹参品质的主导气候因子。研究了丹参在商洛6个不同地区的生长量及有效成分含量差异,并应用灰色关联度分析了其与气候因子的关系,结果表明:6地区丹参有效成分含量均达到药典要求,但品质存在显著差异。年日照和年均降水量是影响丹参根系生长量的主导因子;无霜期与年极高温度是影响丹参素含量的主导因子;7月份均温、年均温度、年极高温度是影响丹参酮IIA含量的主导因子;年日照、无霜期是影响丹酚酸B含量的主导因子。以上几个指标可以作为选择丹参适生基地的参考指标,为科学合理的选择丹参规范化种植基地,保证中成药生产原料质量提供参考。

Grey correlation for main climatic factors and quality of Danshen (Salvia miltiorrhiza Bunge)

Climatic factors are principal for Salvia miltiorrhiza Bunge cultivation in terms of growth and activity of pharmacological compounds. This study was aimed at finding the leading climatic factors affecting Salvia miltiorrhiza Bunge production. Growth and active compounds of Salvia miltiorrhiza Bunge in 6 different areas were investigated and the grey correlation degrees with climatic factors were calculated. Our results have shown that: the compound concentrations of Salvia miltiorrhiza Bunge in 6 different areas have significant differences although all of them could meet the requirements of Chinese Pharmacopoeia. The leading climatic factors that affected growth were annual sunshine hours and rainfall. Meanwhile, the major climatic factors that influenced Danshensu concentration were frost free periods and annual highest temperature; the major climatic factors that influenced tanshinon IIA concentration were July average temperature, annual average temperature and annual highest temperature; Annual sunshine hours and frost free periods were leading factors for salvianolic acid B. This research could provide theoretical basis for the production of high quality Salvia miltiorrhiza Bunge, also for optimizing herb production and regulating herb quality.
