ΜΕΛΕΤΗ ΤΩΝ ΧΗΜΙΚΩΝ ΣΥΣΤΑΤΙΚΩΝ ΤΟΥ ΦΥΤΟΥ GALIUM MELANANTHERUM BOISS

IN THE PRESENT THESIS HAVE BEEN STUDIED THE CHEMICAL CONSTITUENTS OF THE AERIALPARTS OF GALIUM MELANANTHERUM BOISS (RUBIACEAE FAM). USING THE TECHNIQUES PC, TLC, C.C, UV ABSORPTION SPECTROSCOPY, HYDROLYSIS, SUGAR ANALYSIS BY GLC, GLC, HPLC, NMR) THE FOLLOWING CONSTITUENTS WERE IDENTIFIED. IN THE PETROLEUM ETHER: B-CAROTENE (ISOLATED, FATTY ACIDS, STEROLS, 4- MONOMETHYLESTEROLS, 4,4'-DIMETHYLSTEROLS. IN THE METHANOL EXTRACT POLYPHENOLIC COMPOUNDS WERE EXTRACTED ACCORDING TO THE CHAVAUX- PARIS PROCEDURE. THE FOLLOWING COMPOUNDS HAVE BEEN ISOLATED AND IDENTIFIED: APIGENIN, KAEMPFEROL, QUERCETIN., LUTEOLIN, CAFFEIC ACID, SCOPOLETIN, VITEXIN LUTEOLIN-7-0-B-GENTIOBIOSIDE, ORIENTIN, CHLOROGENIC ACID, ISOQUERCITRIN, NICOTIFLORIN (KAEMPFEROL-3-0-B- RUTTIN >RUTIN, ESCULETIN (IDENTIFIED BYHPLC BUT NOT ISOLATED). THE FREE AMINO-ACIDS WERE DETECTED BY TLC AND BY CHROMATOGRAPHY IN BIOTRONIC LC 2000 AUTO-ANALYSER . ASCORBIC ACID HAS BEEN DETERMINED BY TWO METHODS (VOLUMETRIC AND SPECTROPHOTOMETRIC).
