Hastifolins A-G, antefeedant neo-clerodane diterpenoids from Scutellaria hastifolia
2010
From the aerial parts of Scutellaria hastifolia, family Lamiaceae (Labiatae), seven neo-clerodane diterpenoids (hastifolins A-G) were isolated. The products are similar to the known scuteparvin and are characterized by being trans-cinnamoyl derivatives. Structures and stereochemistry were determined by intensive NMR investigation. Six of the products form three pairs of epimers at C-13. Hastifolins A-C showed significant antifeedant activity.
The Diterpenoids from the Genus Hyptis (Lamiaceae)
2009
The genus Hyptis (family Lamiaceae) is known mainly for the essential oils isolated from the aerial parts of several species. Less known are the diterpenoids, extracted from a limited number of species. In consideration of the interest for the structures of this class of compounds, largely occurring in the whole Lamiaceae family, the present paper means to review and update their chemistry. Also the use of many species of Hyptis in folk-medicine is reported.
Structure and Biological Activity of the Furan-Diterpenoids from the Genera Leonotis and Leonurus
2007
The present review, covering the literature up to 2006, reports the chemistry and the biological activities of the diterpenoids occurring in the aerial parts of species belonging to the genera Leonotis and Leonurus, family Lamiaceae.
