Abstract:

Rosa gallica L. cv. Dianhong (ZY) rose and Rosa chinensis Jacq. cv. Crimson Glory (DH) are the main edible rose varieties in Yunnan. In this research, the UPLC-MS/MS method was used to detect the secondary metabolites of these two types of roses. The results showed that a total of 82 metabolites were detected in the two petals, including 55 kinds of amino acids and its derivatives (67.07%), 16 kinds of alkaloids (19.51%), 7 kinds of phenolamine (8.54%), 4 kinds of plumerane (4.88%). Glutathione in ZY was 26.35 times higher than that in DH, which had stronger antioxidant capacity. However, L-asparagine and S-(5'-adenosy)-L-homocysteine were unique substances in DH, which had a significant hypotensive effect. Compared with the DH, 15 metabolites were significantly down-regulated in ZY, which indicated that DH had more nutrition and healthcare functional substances, meanwhile, the unique ingredients of ZY made it have stronger antioxidant capacity.
