冬季采收的人参鲜根甲醇提取物比夏季采收的高两倍。这主要是由于冬季参根中蔗糖大量增加。另一方面,人参根中具生物活性的达马皂甙在夏季却会增加。这说明,在夏季采收人参可获得优质人参提取物。 The ginseng fresh root methanol extract collected in winter is twice as high as the summer harvest. This is mainly due to the large increase in sucrose in winter ginseng roots. On the other hand, biologically active damascene saponins in ginseng roots will increase in the summer. This shows that harvesting ginseng in summer can obtain high quality ginseng extract.
