以夏枯草果穗成熟度(发黄程度)为采收指标,分6个采收期,分别测定其果穗熊果酸含量、种子千粒重与发芽率,并进行对比.结果表明:采收期对夏枯草果穗与种子质量存在明显的影响,熊果酸含量、种子千粒重和发芽率均随果穗成熟度的增加而提高,至果穗全黄时达最大值,果穗全黄7 d后采收,熊果酸含量下降明显,千粒重与发芽率无明显变化.

Study was conducted on influence of different collecting date on changes of ursolic acid content, kernel weight and germination percentage of Prunella vulgaris, taking ear maturity degree as indicator for collecting date. Determination and comparison on content of ursolic acid, kernel weight and germination percentage showed that collecting date obvious effect on ear and seed quality. Ursolic acid content, kernel weight and germination percentage increased with maturity process, and topped when ear turned completely yellow. When collecting 7 days after yellow, its ursolic acid decreased evidently, but kernel weight and germination percentage had no great change.
