PRELIMINARY INVESTIGATION OF SOME HIGHER PLANTS LEAVES INTRODUCED IN THE NATIONAL BOTANICAL GARDEN OF GEORGIA FOR THE CONTENT OF BIOLOGICALLY ACTIVE COMPOUNDS

Abstract

There was carried out preliminary phytochemical analyse of 20 plants, introduced in the National botanical garden of Georgia for the content of flavonoides, coumarines, triterpenic and steroidal saponines. There were revealed some perspective species of plants, which are recommended for more deep study with perspective usage in medicinal practice in the future. For the deep study for the content of flavonoides present interest following plants: Meratia praecox Rehd. et Wils., Aucuba japónica Thunb., Ginkgo biloba L., Parotia persica C.A. Mey, Caesalpinia gilliesii Wall. ex Hook., Cercis сanadensis L., Wisteria sinensis Sweet., Buddleia davidii Franch., Hibiscus syriacus L., Broussonetia papyrifera (L.) L^’Herit.; On the content of coumarines: Nandina domestica Thunb., Buxus balearica Lam., Ginkgo biloba L., Rosmarinus officinalis L., Caesalpinia gilliesii Wall. ex Hook., Hibiscuss yriacus L., Broussonetia papyrifera (L.) L^’Herit., Fraxinus ornus L., Ligustrum lucidum Ait., Osmanthus fragrans (Thunb.) Lour. Steroidal saponines were discovered in the species of plants: Buxus balearica Lam., Meratia praecox Rehd. et Wils., Parotiapersica C.A. Mey, Hibiscus syriacus L. In the point of view of the terpenic compounds is interesting Caryopteris incana Thumb. Mig.
