Abstract


Euphorbia genus (Euphorbia) is a genus of plants Euphorbiaceae (Euphorbiaceae) , there are more than 2,000 species worldwide , and China has more than 80 kinds of rich resources , and various forms of widely distributed , easily found and collected . This genus is characterized by containing a white or yellow - white milk , and has important medicinal value . \According to the literature , the main active ingredient of Euphorbia its the diterpene esters contained . Modern research has shown , Euphorbia also has a very good molluscicidal activity is an excellent plant molluscicidal medicinal plant resources . Currently, due to the serious human destruction of the ecological environment , snails dissemination area expanded schistosome epidemic upward trend , caused widespread concern of the Chinese government and the medical profession . Therefore, Euphorbia molluscicidal test research has far-reaching significance for the prevention and treatment of schistosomiasis . This thesis is summarized overview of the Euphorbia ; using headspace solid phase micro- extraction technology , combined with gas chromatography - mass spectrometry analysis method , volatile and semi - volatile components in the plant sap of Euphorbia on 20 kinds analysis , detected in 75 kinds of chemical ingredients , 72 compounds were identified , of which 37 compounds found in plants for the first time from the Euphorbia genus ; compare five common molluscicidal activity of Euphorbia from screening two plants; development potential and molluscicidal activity of these two the euphorbia different growing season stems , leaves a comparative study . Thus the Euphorbia genus plants into the development of efficient , low toxicity, biodegradable plant molluscicides laid the foundation , and is expected to open up a new way for schistosomiasis control in China studies .
