Proscillaridin A 是从Drimia robusta 中提取的一种天然产物。是强力的拓扑异构酶 I 和 II 的抑制剂，IC50值分别为 30 nM 和 100 nM。

Norswertianolin 是从 G. acuta 中分离得到的化合物，是 CSE 小分子激活剂，提高了 CSE 的 H 代2S 活动，可用于研究心血管疾病。

Vogeloside shows inhibition of nitric oxide production in lipopolysaccharide-activated macrophages; its activity is comparable to that of aminoguanidine, a classic inhibitor.

Swertianolin (Bellidifolin-8-O-Glucoside) 是从Gentianella Acuta 分离得到的一种黄酮，具有抗 HBV 和抗菌活性，可抑制乙酰胆碱酯酶。

1,3,5,6-Tetrahydroxyxanthone shows moderate hepatoprotective activity with EC(50) values of 160.2 +/- 0.6 microM against tacrine-induced cytotoxicity in HepG2 cells. It can inhibit angiotensin-I-converting-enzyme activity in a dose-dependent manner.

1-Hydroxy-2,3,5-trimethoxyxanthone (HM-1) has vasodilator action ,which involves both an endothelium-dependent mechanism involving NO and an endothelium-independent mechanism by inhibiting Ca(2+) influx through L-type voltage-operated Ca(2+) channels; a minor contribution to the effects of HM-1 may be related to inhibition of the protein kinase C-mediated release of intracellular Ca(2+) stores. HM-1,at the concentration of 1 ug/mL, can effectively inhibit the osteoclast differentiation in a co-culture system with mouse osteoblastic calvarial cells and bone marrow cells; it also can protect mice from the acute lung injury induced by ipopolysaccharide (LPS), which is relative to the increasing of IκB-α protein expression and the suppressing of inducible nitric oxide synthase and cyclooxygenase-Ⅱ protein expression.
