Numerical taxonomy study of Salvia sect. Salvia (Labiatae)

Multivariate analysis was carried out in order to elucidate the taxonomic relationships between Salvia officinalis L., the type species of the genus, and S. fruticosa Mill., both taxa included in section Salvia (Labiatae). Seventy-five different herbarium specimens from all over the Mediterranean Region, belonging to these two taxa, were analysed. Twenty-four specimens belonging to S. lavandulifolia Vahl. s.l. , were used as outgroups. Twenty-six morphological characters were measured and a data matrix was constructed prior to multivariate analysis by means of R software. Multiple correspondence analysis was used to obtain a single dendrogram, applying Ward's minimum variance algorithm. This tree was used as a basis to propose a key for the determination of the species and subspecies studied. S. lavandulifolia is separated in two groups, one belonging to S. officinalis and another one representing what was called S. blancoana . Salvia officinalis L. ssp. gallica (W. Lippert) Reales, D. Rivera & Obón and S. officinalis L. ssp. oxyodon (Webb & Heldr.) Reales, D. Rivera & Obón are discussed as new combinations. In addition, a hybrid between S. officinalis and S. fruticosa is identified and its importance in gardening and cultivation is discussed. © 2004 The Linnean Society of London, Botanical Journal of the Linnean Society , 2004, 145 , 353–371.     

Terpenoids from Salvia palaestina

Six known terpenoids: vergatic acid, ursolic acid, crataegolic acid, lupane-3β-,11α, 20-triol, sclareol and sitosteryl 3β-glucoside were isolated from the leaves of Salvia palaestina and were identified by spectral data. Among the compounds, sclareol showed high activity against Staphylococcus aureus, S. epidermis, Escherichia coli, Proteus vulgaris and Pseudomonas aeruginosa, while the triterpenoids were not tested due to solubility problems.     

Diterpenoids from Salvia greggii

From the aerial part of Salvia greggii a previously known diterpenoid, isopimaric acid, and four new natural substances, 3β- and 14α-hydroxy-isopimaric acids, 14α,18-dihydroxy-7,15-isopimaradiene and 7,8β-dihydro-salviacoccin, have been isolated. The structures of these diterpenoids have been established by chemical and spectroscopic means and, in some cases, by comparison with previously known synthetic compounds.

The aerial parts of Salvia hypoleuca afforded two sesterterpenes with a previously unknown carbon skeleton.     

Diterpenoid from Salvia greggii

The structure of a diterpenoid, designated salvigresin, that was isolated from the aerial parts of Salvia greggii, has been confirmed by spectroscopic investigation and X-ray analysis.

The abietane diterpenoid, neocryptotanshinone II, and the known 6,12-dihydroxyabieta-5,8,11,13-tetraen-7-one were isolated as minor components from the roots of Salvia miltiorrhiza. Their structures were established on the basis of spectral evidence.     

Triterpenoids from Salvia deserta

From the aerial parts of Salvia deserta a new oleanane and two new lupane triterpenoids have been isolated, together with five already known ursane, oleanane and lupane derivatives. The structures of the new substances were established by spectroscopic means.     

Diterpenes from Salvia breviflora

In addition to compounds which are ubiquitous in Salvia species, like ursolic and oleanolic acids, we have isolated two heterobicyclic diterpenes, brevifloralactone and brevifloralactone acetate.     

Diterpenoid quinones of Salvia lanata

The petrol extract of the whole plant (aerial parts and roots) of Salvia lanata yielded three diterpenoid quinones of the royleanone type, identifi

Neo-clerodane-type diterpenoids from Salvia keerlii

From the aerial parts of Salvia keerlii two new neo-clerodane diterpenoids have been isolated. Their structures: 8,12(R)epoxyneo-cleroda-3,13(14)-diene-18,19:15,16-diolide, kerlin and 7-acetoxy-12(R)hydroxyneoclerodane-3,13(14)-diene-18,19:15,16-diolide, kerlinolide, have been established by spectroscopic means.
