RESUMO
As a common medicine and homologous plant, Nelumbo nucifera mainly contains alkaloids, flavonoids, glycosides, terpenes, steroids, fatty acids, proteins, minerals, vitamins and other chemical constituents, with lipid-lowering, antibacterial, anti-inflammatory, antioxidant, hemostasis and other pharmacological activities. After reviewing the literatures at home and abroad for nearly 40 years, 385 compounds have been reported from different parts of N. nucifera including lotus leaves, plumula nelumbinis, lotus, lotus seeds, lotus root, lotus seedpod, nelumbinis rhizome node, lotus stem, N. nucifera stamens and lotus seed skins. There are 86 alkaloids, 133 flavonoids, and 166 other compounds. In this review, we summarized the chemical constituents and pharmacological effects reported in N. nucifera, and it provides a reference for further study on the chemical constituents, pharmacological activity and development and utilization of N. nucifera.
RESUMO
Objective To study the hemostasis activity of iodine complex with carboxymethyl chitosan .Methods The polymers were prepared with azodiisobutyronitrile as the initiating agent and sodium acrylate ,N‐vinylpyrrolidone ,carboxym‐ethyl chitosan and N ,N′‐methylene diacrylamide as the raw materials .It was then complexed with iodine to generate iodine complex with carboxymethyl chitosan ,and the hemostasis activity was tested at the same time .Results The polymers could absorb water with the value of 103g/g and showed potent hemostasis activity for auricular veins and femoral veins .Conclusion The results showed that hemostatic effect of polymers was better than that of hemostatic sponge and Quikclot .
