白花牛角瓜Calotropis procera(Ait)R.Br.乳胶中含有一定量的蛋白。尽管某些蛋白随着分离过程留存在橡胶样部位中,然而仍测得其质量浓度达4.5mg/mL。作者研究了水溶性蛋白(LP)在体外、体内实验中的可消化性,该蛋白在先前的研究中对动物产生明显的毒性。在体外实验中,将LP5mg/mL

Carbotropis procera (Ait) R. Br. latex contains a certain amount of protein. Although some of the proteins remained in the rubber-like site as the separation progressed, their mass concentration was measured to be 4.5 mg/mL. The authors studied the digestibility of water-soluble protein (LP) in in vitro and in vivo experiments, and the protein was significantly toxic to animals in previous studies. In vitro experiments, LP 5mg/mL
