The aerial parts of Teucrium yemense yielded two iridoid glycosides. Their structures were elucidated by spectral means as teucardosid and 8-O-acetylharpagid.
In the course of our continuing search for novel cancer chemopreventive agents from natural sources, several kinds of Labiatae plants were screened. Consequently, the iridoid glycoside derivative, 8-acetylharpagide (8-AcHarp), was obtained from the flowering whole plant of Ajuga decumbens as

Growth inhibitory activities and nutritional indices of catalpol (1), 8-O-acetylharpagide (2), and harpagide (3) were determinated in larvae and adults of Tribolium castaneum, respectively. Compound 1 produced a series of allelochemical effects probably related with the DNA synthesis. This iridoid

To investigate the chemical constituents of Galeopsis bifida. Various chromatographic techniques were employed for isolation and purification of the constituents. The structures were elucidated by chemical and spectral analyses. Ten compounds were isolated and identified as chrysoeriol(1), 5,7-dihydroxy-3',4'-dimethoxyflavone(2), hederagenin(3), daucosterol(4)

We have identified a novel nonsteroidal ecdysteroid agonist. This compound was isolated from a methanol extract of Ajuga reptans L. (Lamiaceae) and the structure was identified by spectroscopic methods as 8-O-acetylharpagide. We have characterised this compound as an ecdysteroid agonist
