The reported investigation of the constituents of the petroleum ether extract of the root of Salvia officinalis L. confirmed the presence of the following diterpene quinones: 12.hydroxy-8, 12-abietadiene-11, 14-dione (royleanone), 7 alpha, 12-dihydroxy-8.12-abistadiene-11-14-dione (horminone) and 7
The mechanism of action of quinones from the roots of Salvia officinalis L. (royleanones) and terpenoid phenolaldehydes from the leaves of Eucalyptus viminalis Labill. (euvimals) was studied. Royleanones and euvimals displayed marked protonophoric activity on artificial bilayer lipid membranes in
Three diterpenoid quinones (royleanone- SAR 3, horminone- SAR 26, and acetyl horminone- SAR 43) isolated from the roots of Salvia officinalis L. were tested for their cytotoxic and DNA-damaging activity in human colon carcinoma cells Caco-2 and human hepatoma cells HepG2 cultured in vitro.
BACKGROUND
The genus Salvia, with nearly 900 species, is one of the largest members of Lamiaceae family. In the Flora of Iran, the genus Salvia is represented by 58 species of which 17 species are endemic. Salvia hypoleuca Benth., is one of these species growing wildly in northern and central parts
Comparative studies on the volatile and non-volatile fractions of 6 species. i.e. Salvia officinalis, S. tomentosa, S. fruticosa, S. candelabrum, S. ringens, S. lavandulifolia of the Section Salvia (Lamiaceae) have been carried out. Both fractions provide the chemical pattern matches to the
Seven diterpenoids, 3-ketosapriparaquinone ( 1), salvilenone, 3-hydroxysalvilenone ( 2), arucadiol, royleanone, sugiol, and ferruginol were isolated from the root of SALVIA PRIONITIS Hance (Labiatae); Compounds 1 and 2 are new natural products. The structure of 1 was established through the
BACKGROUND
The phytochemical and biological studies carried out on Salvia species showed that their extracts and constituents have various biological activities.
OBJECTIVE
The aim of this study was the isolation of diterpenoids from the roots of Salvia barrelieri Ettling and the determination of the
From the aerial parts of Chinese Salvia miltiorrhiza Bunge a novel sesquiterpene (1), which possesses a rare substitution pattern, together with seven known abietane type diterpenes has been isolated. Structure 1 was elucidated on the basis of spectral analysis, including 2D-NMR spectroscopy,
BACKGROUND
Salvia sessei Benth, popularly known as "pipilolxochitl" or "sabanito", is a plant utilized in Mexico in traditional medicine for the treatment of erysipela. To date, only one report, to our knowledge, has been found in which a royleanone-type diterpene of the aerial parts of the species
Bioguided-fractionation of an acetone extract of the roots of Salvia cilicica (Lamiaceae) led to isolation of two new diterpenes, 7-hydroxy-12-methoxy-20-nor-abieta-1,5(10),7,9,12-pentaen-6,14-dione and abieta-8,12-dien-11,14-dione (12-deoxy-royleanone), together with oleanolic acid, ursolic acid,
NMR and NP-HPLC-UV profiling of the exudate of Salvia corrugata revealed that its secondary metabolite composition was largely dominated by α-hydroxy-β-isopropyl-benzoquinone diterpenoids. Among them, four diterpenes not described previously were isolated and identified as fruticulin C (3),
Hairy roots of Salvia austriaca Jacq. transformed with Agrobacterium rhizogenes strain A4 were obtained and transgenic status of the roots was confirmed by polymerase chain reaction (PCR) using rolB and rolC specific primers. The root cultures growing in half-strength Gamborg (1/2 B5) liquid medium
The cytotoxic activities of the n-hexane, chloroform and aqueous methanolic fractions prepared from the methanolic extract of the leaves of 23 Salvia taxa were studied for their cell growth-inhibitory activity against human cervix adenocarcinoma (HeLa), skin carcinoma (A431) and breast
Four abietane-type terpenoids, including two known royleanones and two new, rearranged 20-norabietanes, were isolated from the roots of the Iranian medicinal plant Salvia hydrangea DC. ex Bentham (Lamiaceae), which is used as an anthelmintic and antileishmanial remedy. Their structures were
