百合科萱草属植物是经改良的园种植物,广泛分布于南欧至亚洲温带地区。重瓣萱草(Hemerocallis fulva)根在中国用于利尿、止血和消炎,而且具有安眠(延长睡眠)作用。在日本冲绳,人们食用其春生的嫩叶。进一步研究,从重瓣萱草中分离出一些氨基酸衍生物,如黄萱草氨酸A～E(fulvanines A～E)。本次首次从萱草属植物中分离出2种新型甾类皂苷,名为萱 Liliaceae Humulus is a modified garden plant widely distributed in temperate regions of southern Europe to Asia. Hemerocallis fulva root is used in China for diuresis, hemostasis, and anti-inflammation, and it has a hypnotic (prolonged sleep) effect. In Okinawa, Japan, people eat their spring leaves. Further study, some amino acid derivatives were isolated from Valeriana vulgaris, such as valsartan A to E (fulvanines A to E). For the first time, two new types of terpenoid saponins were isolated from the plants of the genus Hemerocallis.
