Rosa roxbughii Tratt (RRT) is a welcome medicinal and edible fruit with unique functions and nutrients in China. In the past decades, extensive research including chemical constituents and bioactivities of RRT were reported. A total of small 78 small molecules, such as flavonoids, organic acid, triterpenes, etc. and 11 polysaccharides have been isolated from RRT. Its antioxidant, anti-tumor and other pharmacological effects were also discovered. This paper reviews the progress of those information for the R&D of RRT in the future.

Gynostemma pentaphyllum is a functional food that is commercially available worldwide. Triterpenoid saponins are the main active components in Gynostemma pentaphyllum, which are usually hydrolyzed into triterpene sapogenins in organisms to play a pharmacological role. Gypensapogenin D is a triterpene sapogenins with the highest content in the hydrolysate of gypenoside. In addition, it was found that Gypensapogenin D had a certain inhibitory effect on α-glucosidase. In view of the poor solubility of Gypensapogenin D, which affects its bioavailability, Gypensapogenin D was prepared as a liposomal formulation in this paper, which provides valuable data for the later in-depth study and drug development and utilization of this compound.
