Abstract
The thesis is divided into four Parts :-Part I : Phytochemical investigation of sugar beet leaves. Chapter 1 : Preliminary Phytochemical screening of sugar beet leaves. Chapter 2 : Phytochemical screening of sugar beet leaves. Chapter 3 : GC/MS analysis of oily fractions of sugar beet leaves. chromatographic investigation of different extracts of leaves afforded five pure compounds which are 24-methylene-cycloarta-24(30)-en-3β-ol, 24-methylene-29-norcycloarta-24(30)-en-3β-ol (cycloeucalenol) (4-monomethyl cycloartane triterpene), β-sitosterol, betacyclofarnesane a new rearranged cyclofarnesane sesquiterpene and 4-methyl heptyl benzoate, this is the first report of isolation of this compound from any natural source, The subfraction (1-22) of petroleum ether extract of leaves (fixed oil) found to be oily in nature so it was subjected to GC/MS after esterification, found to contain 23.22% hydrocarbons and 74.32% oxygenated compounds, the most abundance compound is 1-Decanol, 2-hexyl (41.89%).Part II : Phytochemical investigation of sugar beet fruits. Chapter 1 : Preliminary phytochemical screening of sugar beet fruits. Chapter 2 : Phytochemical screening of sugar beet fruits. Chapter 3 : GC/MS analysis of oily fractions of sugar beet fruits. Chapter 4 : Study of sugar beet fruit pigments. chromatographic investigation of different extracts of fruits afforded four compounds which are 1-nonadecanol, palmitoleic acid, 1, 2, 2- trimethyl hydrazine carboxylic acid. Atisine-11, 20-dione, 16. 17- dihydro, 17-benzoyloxy, 21-isopropyl-4-methylene hydroxyl. The oily fraction was subjected to GC/MS indicate that the most abundance compound was Hexadecanoic acid, methyl ester. Methylene chloride extract of fruits was containing pigments of betalain type and these were identified by UV and Mass spectroscopy as amaranthin or iso amaranthin and indicaxanthin, these pigments were subjected to cytotoxicity assay adopting MTT assay, the results show potent cytotoxic activities against HFB4 (Human skin cancer) cell. Part III : Biological study of fruits and leaves of sugar beet. Part IV: Botanical study of the leaves and petiole of sugar beet.
