牵牛子(黑丑)化学成分的初步研究 . Studies on The Chemical Constituent of Pharbitis purpurea (L.) Voight seed

Abstract

he chemical constituents of Pharbitispurpurea( L.) Voightseedshave been studied. The result showed:the contentof its fatty oil reaches1 7.50 % ,there are plenty of fatty acids which is necessary for human body in the seed oil.The main composition were:palmitic acid ( 1 5.0 7% ) , stearicacid( 1 0 .0 2 % ) ,oleicacid( 2 9.55% ) ,linonic acid( 3 2 .0 4% ) ,linolenicacid( 7.0 3 % ) ,etc,and eighteen kinds of amino acids,twenty-fourkinds of minerals elements from the seed were also detect- ed.Therewere eightkinds of essential amino acids forhuman body ,which makesup to 3 4.98% of its total amino acid in its seed.The kindsof mineral elementswere rich,the contentof Fe、Mn、Cu、Zn and Ca are higher.The seed and its oil were of higher potential value in nutrientand medical effect.
