Thirteen compounds were isolated from the CH2Cl2 fraction of Machilus thunbergii as phospholipase Cgamma1 (PLCgamma1) inhibitors. These compounds were identified as nine lignans, two neolignans, and two flavans by spectroscopic analysis. Of these, 5,7-di-O-methyl-3',4'-methylenated (-)-epicatechin

From the chloroform-soluble portion of the stem wood of Machilus obovatifolia, one new neolignan, perseal F (1), four known neolignans, perseal G (2), licarin A, licarin B, acuminatin, two butanolides, linderanolide E and isolinderanolide E, two steroids, beta-sitosterol,

A methanol extract of mace, the aril of Myristica fragrans (Myristicaceae), was found to inhibit the release of β-hexosaminidase, a marker of antigen-IgE-stimulated degranulation in rat basophilic leukemia cells (RBL-2H3, IC50 = 45.7 μg/ml). From the extract, three new 8-O-4' type neolignans,

A simple and rapid method, based on matrix solid-phase dispersion (MSPD) and high-performance liquid chromatography (HPLC) was developed for simultaneous determination of nine lignans, including (-)-(7R,8R)-machilin D (Wang, C., Wang, P., Chen, X., Wang, W., Jin, Y.; Saururus chinensis (Lour.) Baill
