Plaunotol [(2E, 6Z, 10E)-7-hydroxymethyl-3,11,15-trimethyl-2,6,10, 14-hexadecatetraen-1-ol)] is an acyclic diterpene alcohol originally isolated from the plant Croton sublyratus, which is native to southeast Asia. Plaunotol has been used to treat gastritis and gastric ulcers in Japan. Plaunotol increases the prostaglandin production in the gastric mucosa and accelerates ulcer healing. The precise mechanisms underlying the gastroprotective actions by plaunotol are not known. On the other hand, cyclooxygenase (COX)-2 is a key enzyme in PGE(2) production and its induction is thought to have an important role in ulcer healing. Plaunotol induced COX-2 expression and increased PGE(2) production in serum-starved RGM1 cells via activation of the NF-kappaB and CRE sites of Cox-2 gene promoters. In vitro studies showed bactericidal action against H. pylori by increasing membrane fluidity, leading to autolysis and deterioration of cell structure

Sample Use Guides

In Vivo Use Guide

Five male and five female ICR mice were treated with either water for the control group or purified plaunotol extract (PPE) at 2.5, 5, 10, and 20 g/kg for each treatment group.

Route of Administration: Oral

In Vitro Use Guide

10 and 1 μg/ml (33 and 3.3 μmol/l) plaunotol induced toxicity in human gingival fibroblasts (HGFs) and human oral keratinocytes (HOKs), respectively. However, 0.1 μg/ml (0.33 μmol/l) plaunotol promoted HGF proliferation and wound healing in monolayer and FPCL models. In contrast, 0.1 μg/ml plaunotol could not induce HOK proliferation nor in vitro wound healing using monolayer culture, but it induced wound healing in a modified FPCL model.
