The long-stem aristolochin and neosonarin I contained therein have an inhibitory effect on the reverse transcriptase infecting mouse leukemia virus cells. The LD50 of mice fed these two components was greater than 100 mg/kg.
2. The detoxification and choleretic effect rose water decoction can relieve the toxicity of oral antimony in mice, but it is only effective for oral antimony potassium tartrate, and at the same time its anti-schistosomiasis effect disappears, so this effect may be related to rose water The decoction changes the structure of antimony potassium tartrate.

The extract contains active ingredients that directly dilate blood vessels, not due to the influence of the acidic substances contained therein.
7. Antioxidant effect Rose extract not only has significant antioxidative effect on aging mice at the tissue level and cell level, but also can increase gene expression at the molecular level.
8. Anti-diabetic effect The methanol extract of rose has a strong non-competitive inhibitory effect on α-glucosidase in a dose-dependent manner. The anti-diabetic effect of rose flower may be through inhibiting the absorption of carbohydrates from the intestinal tract, which reduces postprandial hyperglycemia.
