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.

6'-O-beta-D-Glucosylgentiopicroside (6'-O-Glucosylgentiopicroside) 是一种环烯醚萜，分离自G. straminea 根中。它能显著抑制 fMLP 诱导的超氧化物生成。

Quassin has female anti-fertility properties, possibly acting via inhibition of estrogen secretion.

Ailanthone (AIL) 是一种来自臭椿Ailanthus altissima的天然通过抗肝癌(HCC)成分，可通过降低 cyclins 和 CDKs 的表达、提高 p21 和 p27 的表达来诱导 G0/G1 期细胞周期阻滞。Ailanthone 同时也是一种有效的雄激素受体 (androgen receptor (AR)) 抑制剂，能够抑制完整雄激素受体(IC50:69 nM)、持续活跃剪切变体(IC50:309 nM)

Nigakinone 是一种苦木中含量丰富的生物碱，具有重要的药理活性。

Eurycomanone (Pasakbumin A) 能够抑制雌激素生成过程中磷酸二酯酶和芳香酶的活性，促进精子生成。它对 HepG2 细胞具有细胞毒性，能够上调 p53 和 Bax 以及下调 Bcl-2 ，诱导细胞凋亡。它具有抗癌活性，在浓度范围内以剂量依赖性方式抑制 A549 肺癌细胞增殖 从 5 到 20 微克/毫升。

Lawsone (Hennotannic acid) 是一种从Lawsonia inermis 的叶片中分离得到的萘醌染料，具有抗菌和抗氧化活性。

Corosolic acid (Colosic acid) 是从大花紫薇中提取的一种天然产物，具有抗肿瘤活性。
