摘要
为探究河南产丹参的适宜采收时期,测定了河南产丹参不同采收期根干质量、丹参酮ⅡA含量和丹酚酸B含量以及这2种有效成分的产量。结果显示,嵩县、伊川、方城3个种源的丹参中丹参酮ⅡA和丹酚酸B含量均在7月份达到最高,而丹参根干质量均在11月份达到最大,丹参有效成分含量最大的时间和丹参产量最高的时间不重叠。这3个种源丹参的丹参酮ⅡA和丹酚酸B产量(根干质量×有效成分含量)从3月到11月均逐渐增加,并在11月达到最大。采收时间对河南产丹参的2个有效成分含量、根干质量及有效成分产量均有较大影响。综合考虑,以丹参有效成分产量为标准,确定河南产丹参的适宜采收期为11月。
To research the optimal harvesting time of Salva miltiorrhiza Bge. in Henan,the dry weight of roots,the contents of tanshinone Ⅱ A and salvianolic acid B,and the yield of the above two active ingredients of Salva miltiorrhiza Bge. were measured and analyzed in Henan in different harvesting time.The results showed that for the Salva miltiorrhiza Bge. originated from Song county,Yichuan county,Fangcheng county,the dry weight of roots were greatest in November,the contents of tanshinoneⅡA and salvianolic acid B were highest in July,and the time when the contents of the two active ingredients reached the maximum did not overlap that the yield reached the maximum. The yield of the two active ingredients were gradually increased from March to November,and reached the maximum in November.The harvesting time had a great influence on the contents of the two active ingredients,dry weight of roots and the yield of the two active ingredients of Salva miltiorrhiza Bge. in Henan. Comprehensive consideration,with the yield of active ingredients as the standard,November was the most suitable harvesting time for Salva miltiorrhiza Bge. in Henan.
