目的确定四川大邑县金银花的采收标准。方法 2012~2014年连续三年对四川大邑县金银花种植基地2011年栽种的三年生扦插苗三青、二白、大白及花期等不同生长阶段的花蕾干重、长度、上部直径、下部直径及药材品质进行测定。结果 3年生扦插苗定植后的第二年、第三年、第四年,单花干重呈极显著上升趋势;花蕾长度、花蕾下部直径等外部性状在第三年显著增大,第四年增幅不明显。随着花蕾的逐步开放,外部形态逐步增大,但单花干重逐步减小。3个年度三青、二白、大白期绿原酸、木犀草苷含量均显著高于药典标准。结论四川大邑县金银花采收应根据当年实际情况采收大白期及二白期较大的花蕾。
Objective To determine the Dayi County, Sichuan honeysuckle harvesting standards. Methods From 2012 to 2014, the dry weight, length, upper diameter, lower diameter of buds of three-year-old cutting seedlings of three-year-old cutting seedlings in Dayi County, Dayi County, Sichuan Province, The quality of herbs was determined. Results In the second year, the third year and the fourth year after planting, the dry weight of single flower increased significantly. The length of flower bud, the diameter of lower part of flower bud increased significantly in the third year. In the fourth year Increase is not obvious. With the gradual opening of buds, the external shape gradually increased, but the dry weight of single flowers gradually decreased. The contents of chlorogenic acid and luteolin in three green, two white and big white phases were significantly higher than Pharmacopoeia standards. Conclusion The harvesting of honeysuckle in Dayi County, Sichuan Province should be based on the actual conditions of the year to harvest the larger white buds and the larger buds of the second white stage.
