Study On Chemical Constituents Of Fatty Contents From Coral Chromonephthea Sp.

Because of marine natural products' unique chemical constitutions and their variety of bio-activities, any further research in them will be of great significance in chemical theory and application in terms of enriching the knowledge of Natural Products Chemistry, discovering new medicines against disease and boosting the development of basic theory and synthesis in Organic Chemistry.Based on a comprehensive study on chemical constituents of fatty contents from a new species of soft corals Chromonephthea sp. collected from Naozhou Island in Zhanjiang City, this dissertation is an exact report about my research in which four compounds including one new compound are obtained. Their chemical structures are elucidated on the basis of HPLC-MS, EI, ESI, FAB, ¹HNMR, ¹³CNMR 2DNMR spectroscopic analysis and comparison with the literatures. These four compounds include 3-Heptadecyloxy-propane-1, 2-diol(1), 24-Methylene -cholest-4-ene-3β, 6β-diol(2), N-(2-phenylethyl)-Acetamide(3), cholest -3-one-12β, 16β, 22α-triol(4). These compounds are isolated from soft corals Chromonephthea sp. for the first time and compound 4 is a new compound.
