The necessity of the dissertation subject In Vietnam seven Paramignya species have been identified distributed mostly in the south of the country. Paramignya trimera Oliv. Guill. local name Than duoc or Xao tam phan is an endemic plant in South Vietnam. The stems and roots of the plant have been used in folk medicine to treat liver disease especially cirrhotic ascites. Morinda longissima . Ruan. Rubiaceae is a small-to- medium tree contributed in mountainous area in the North provinces of Vietnam. The stems and roots of medicinal plant Morinda longissima has been used by Thai s ethnic people in Son La and Lai Chau provinces for treatment of liver disorders collitis and oedema. Therefore the task of studying their chemical composition and biological activities of Morinda longissima and Paramignya trimera species in our country is important and urgent. From that point the topic Research on chemical compositions and biological activities of Paramignya trimea Oliv. Guill. .
