Delta-Tocopherol, an isomer of Vitamin E, possesses antioxidant activity and may serve as an effective ingredient in whitening cosmetics with reduced skin toxicity.

(E)-Ferulic acid methyl ester (Methyl (E)-ferulate) is a potential inhibitor of the mitogen-activated phosphor kinase pathway and an anti-inflammatory agent first isolated from the medicinal plant S. tuberosa. Additionally, it shows promising anthelmintic activity against Haemonchus contortus.

1. Tuberostemonine (Tuberstemonine) exhibits relatively higher intestinal permeabilities. 2. Tuberostemonine acts in part as an open-channel blocker at the crayfish neuromuscular junction.

1. Protostemonine has anti-inflammatory activity, it effectively attenuates LPS-induced inflammatory responses in vitro and in vivo; the beneficial effects are associated with the decreased phosphorylation of MAPK and AKT and the reduced expression of pro

Dehydro-δ-tocopherol shows antioxidant capacities.

Stilbostemins N may exhibit moderate antibacterial activities.

Neostenine shows significant antitussive activity.

Stilbostemin A, stilbostemin B , stilbostemin D , stilbostemin F , and stilbostemin G show structure-dependent inhibition of leukotriene biosynthesis with IC(50) values ranging from 3.7 to >50 microM.
