Chemical profile and pancreatic lipase inhibitory activity of (Sieb.) Makino leaves.

Background: (Sieb.) Makino () is one species of bamboo distributed in China, Japan and Vietnam. The chemical profile of its leaves and its potential application was unknown yet.

Identification and quantification of main flavonoids in the leaves of cv. .

The chemical profile of cv. () leaves was analysed by UPLC-DAD-Q-TOF-MS. Twelve compounds were identified and -glycosyl flavonoids, including vitexin, isovitexin, isoorientin and its derivatives, are the main constitutes of the plant.

Immunological effect of subunit influenza vaccine entrapped by liposomes.

Objective: To elevate the immunological effect of subunit influenza vaccine in infants and aged people (over 60) using liposomal adjuvant in the context of its relatively low immunity and to investigate the relation between vaccine antigens and liposomal characteristics.

Methods: Several formulations of liposomal subunit influenza vaccine were prepared. Their relevant characteristics were investigated to optimize the preparation method.
