蛋白质是由 2 0种氨基酸构成的高分子化合物 ,蛋白质分子中 ,氨基酸分子以肽键形式相互连接 ,形成一条多肽键。由于蛋白质在生物体所有生化过程中起着重要作用 ,而且还具有药理活性。因此 ,对含蛋白质和多肽类抗癌植物进行筛选 ,近半个世纪以来引起了人们的高度关注。从紫茉莉 Proteins are high-molecular compounds composed of 20 amino acids. In protein molecules, amino acid molecules are linked to each other in the form of peptide bonds to form a polypeptide bond. Since proteins play an important role in all biochemical processes of organisms, they also have pharmacological activities. Therefore, the screening of protein and peptide-containing anti-cancer plants has attracted people’s attention for nearly half a century. From Mirabilis
