New triterpene glucosides from the roots of Rosa laevigata Michx.
Two new ursane-type triterpene glucosides, 2alpha,3alpha,24-trihydroxyurs-12,18-dien-28-oic acid beta-D-glucopyranosyl ester (1) and 2alpha,3alpha,23-trihydroxyurs-12,19(29)-dien-28-oic acid beta-D-glucopyranosyl ester (2), were isolated from the roots of Rosa laevigata, together with three known compounds: 2alpha,3beta,19alpha-trihydroxyurs-12-en-28-oic acid beta-Dglucopyranosyl ester (3), 2al...
متن کاملStudy on Thin Layer Drying of Rosa laevigata Michx
The drying process of traditional Chinese medicine Rosa laevigata Michx was investigated in a laboratory scale dryer. Drying experiments were conducted at five temperatures of 40 ̊C, 50 ̊C, 60 ̊C, 70 ̊C and 80 ̊C. The experimental data were fitted to ten different thin layer drying models to select a suitable model for describing the drying process of Rosa laevigata Michx fruits. The results showed ...
متن کاملInduction of substantial myocardial regeneration by an active fraction of the Chinese herb Rosa laevigata Michx
BACKGROUND The replacement of lost cardiac tissues by regenerated myocardium would be a therapeutic ideal for myocardial infarction. The objective of this study was therefore to evaluate the ability of an active fraction that was isolated from Rosa laevigata Michx in therapeutic cardiomyogenesis in a myocardial infarction rat model. METHODS The myocardial infarction animal model was induced b...
متن کاملProtective Effect of the Total Saponins from Rosa laevigata Michx Fruit against Carbon Tetrachloride-Induced Liver Fibrosis in Rats
In this study, the protective effect of the total saponins from Rosa laevigata Michx (RLTS) against liver fibrosis induced by carbon tetrachloride (CCl4) in rats was evaluated. The results showed that RLTS significantly rehabilitated the levels of alanine aminotransferase, aspartate aminotransferase, malondialdehyde, glutathione, glutathione peroxidase, catalase, superoxide dismutase, hydroxypr...
متن کاملThe antioxidant activity and hypolipidemic activity of the total flavonoids from the fruit of Rosa laevigata Michx
In the present work, the antioxidant activity in vitro and hypolipidemic activity of the total flavonoids (TFs) from the Rosa laevigata Michx fruit was evaluated, and the antioxidant effect in vivo was also discussed. The TFs exhibited a high scavenging effect on 2, 2-diphenyl-1picrylhydrazyl (·DPPH) with IC50 values 0.01 mg/mL, and a stong reduce power in the test. Hyperlipemic mice were intra...
