目的:研究气候因子对湘西地区菝葜主要药效成分含量的影响,为指导菝葜引种驯化栽培和规范种植提供依据。方法:采用高效液相色谱法测定湘西地区8个县市野生菝葜药材主要药效成分黄杞苷和落新妇苷的含量,并以此为因变量,以各样地的年均温、1月均温、7月均温、≥10℃有效年积温、年最高温、年最低温、年降水量、年日照量、无霜期和相对湿度10个指标为自变量,进行偏最小二乘法回归分析(PLS)。结果:相对湿度、年最低温和年降水量是影响菝葜主要药效成分含量的主导因子。年最低温、年均温和≥10℃有效年积温与菝葜品质呈正相关,而相对湿度、年降水量和无霜期与菝葜品质呈负相关。结论:气候因子与药效成分相关性的基础工作为菝葜资源的保护、引种驯化栽培及资源的可持续利用提供了科学依据。
Objective: To study the influence of climatic factors on the main medicinal components of Emu owl in western Hunan Province, and to provide evidence for the introduction, domestication and cultivation of Cannabis sativa. Methods: HPLC and HPLC were used to determine the content of the main active components of Huangqioside and Astilbin in the medicinal materials of wild shrews in eight counties of western Hunan. Based on this, the average annual temperature, Monthly average temperature, July average temperature, ≥10 ℃ effective annual accumulated temperature, annual maximum temperature, annual minimum temperature, annual precipitation, annual sunshine, frost-free period and relative humidity as independent variables, partial least-squares regression analysis (PLS). Results: The relative humidity, annual minimum temperature and annual precipitation are the main factors that affect the content of major medicinal components of Emu owl. The annual minimum temperature, average annual temperature ≥10 ℃ effective annual accumulated temperature is positively correlated with 菝 葜 quality, while relative humidity, annual precipitation and frost-free period are negatively correlated with 菝 葜 quality. CONCLUSION: The basic work of the correlation between climatic factors and pharmacodynamic components provides a scientific basis for the conservation of lynx resources, domestication and domestication, and the sustainable use of resources.
