Loureirin C can inhibit the activities of thrombin in vitro effectively.

4',5-Dihydroxyflavone is a soybean LOX-1 inhibitor (Ki: 102.6 μM) and a yeast α-Glucosidase inhibitor (IC50: 66 μM).

4,4′-Dihydroxy-2,6-dimethoxydihydrochalcone is isolated from the stem wood of Dracaena loureiri.

Loureirin B can downregulate the expression of fibrosis-related molecules by regulating MMPs and TIMPs levels, inhibit scar fibroblast proliferation and suppress TGF-β1-induced fibrosis, during which TGF-β1/Smad2/3 pathway is likely involved.

Obtucarbamate A, isolated from *Disporum cantoniense*, exhibits antitussive activity and demonstrates a significant inhibitory effect against neuroinflammation with an IC50 value of 10.57 μM.

7,4'-Dihydroxy-8-methylflavan can significantly promote mesenchymal stem cells (MSCs) osteogenic differentiation by increasing the levels of alkaline phosphatase (ALP) activity. 7,4'-Dihydroxy-8-methylflavan also has free radical scavenging properties.

Obtucarbamate B has antitussive activity.

3-Hydroxy-4',5-dimethoxystilbene, a natural product of Dracaena, Liliaceae, with catalog number TN2941 and CAS number 58436-29-6, can be used as a reference standard.

Mannioside A has anti-inflammatory activity, inhibits carrageenan-induced paw edema in the rat.

2,4,4'-Trihydroxydihydrochalcone is a natural product from Dracaena draco.

7-Hydroxy-3-(4-hydroxybenzyl)chroman shows moderate inhibitory activity against a chymotrypsin-like activity of the proteasome.
