There are 34 Phlomis L. species (Labiatae) growing in Turkey. Some Phlomis species are used as tonics and stimulants in Anatolia . During our systematic phytochemical investigations of Phlomis species we have studied P. linearis Boiss. & Bal.3−6, Phlomis armeniaca Willd., Phlomis pungens Willd. var. pungens 8−10, Phlomis pungens Willd. var. hirta Velen, Phlomis bourgaei Boiss., and Phlomis long...

Repeated column chromatographic separation of the CH2Cl2 extract of Artemisia stolonifera (Asteraceae) led to the isolation of a triterpene (I), a sesquiterpene (II), two aromatic compounds (III and IV) and a benzoquinone (V). Their structures were determined by spectroscopic means to be simiarenol (I), (1S,7S)-1beta-hydroxygermacra-4(15),5,10(14)-triene (II), 3'-methoxy-4'-hydroxy-trans-cinnam...

As part of our systematic study of Korean toxic mushrooms, we have investigated the constituents of Amanita subjunquillea. The column chromatographic separation of the MeOH extract of A. subjunquillea led to the isolation of four ergosterols, two cerebrosides and four cyclopeptides. Their structures were determined by spectroscopic methods to be (22E,24R)-5alpha,8alpha-epidioxyergosta-6,9,22-tr...

Seven phenolic compounds were isolated from a MeOH extract of the leaves of Grevillea robusta. Their structures were determined by various spectral methods including 2D NMR spectroscopy.
