PRELIMINARY STUDY OF SOME PLANTS DISTRIBUTED AND CULTIVATED IN GEORGIA ON THE CONTENT OF BIOLOGICALLY ACTIVE SUBSTANCES

Abstract

Preliminary studies were conducted on 74 analytical samples of 11 families, 25 genera, and 34 species of the Georgian flora on the content of biologically active compounds - flavonoids and triterpene secondary metabolites. The preliminary analysis of the objects revealed that most of them contain flavonoids in the above-ground organs. Datisca cannabina L. was a rare exception, the presence of flavonols was confirmed in its underground parts. The following species were distinguished by their flavonoid content: Polygonatum glaberrimum, Echium vulgare, Cerinthe minor, Datisca cannabina, Rhododendron brachycarpum, Rhododendron delavayi, Rhododendron ungernii, Astragalus brachycarpus, Cercis siliquastrum, Cytisus caucasicus, Cytisus hirsutissimus, Onobrychis kachetica, Genista patula, Vaccaria segetalis, Hypericum perforatum, Stachys iberica, Satureja laxiflora, and Clematis orientalis.

The flavonol glycoside 2´, 3, 5 - tri-hydroxy - 7 - methoxy - flavone - 3 - O - [O - α - L - rhamnopyranosyl - (1→6) - β - D - glucopyranoside (datin-3-rutinoside or datinoside) has been isolated and identified from the roots of Datisca cannabina.

The following species are distinguished by the content of triterpene secondary metabolites: Astragalus brachycarpus, Cerinthe minor, Echium vulgare, Datisca cannabina, Rhododendron brachycarpum, Rhododendron delavayi, Rhododendron ungernii, Cercis siliquastrum, Cytisus caucasicus, Cytisus hirsutissimum.

From the analysed samples, the following species, common in Georgia were studied for the first time on the content of triterpene compounds: Argyrolobium biebersteinii, Astragalus brachycarpus, Datisca cannabina, Cerinthe minor, Echium vulgare, Polygonatum glaberrimum, Rhododendron brachycarpum, Rhododendron delavayi, Spartium junceum, Vaccaria segetalis, Rhododendron ungernii, Genista patula, and Clematis orientalis.
