Study on the in Vitro Inhibitory Activity of Peony Seed Blended Oil on α-Amylase and α-Glucosidase

In recent years, China has been suffering from an increasing number of patients with chronic diseases such as diabetes, hypertension, and heart disease, which are gradually showing a "younger" trend. As health problems become more prominent, choosing good cooking oil has become crucial. People are beginning to realize the significance of a balanced diet and healthy eating habits in maintaining good health. Peony seed oil is rich in nutrients, and its content of unsaturated fatty acids can reach over 85%, with the highest content of α-linolenic acid, which effectively lowers blood sugar. Suppose soybean oil and rapeseed oil are combined and added. In that case, the original efficacy of peony seed oil can be complemented and enhanced, its mechanism of action network can be sound, and its nutritional composition can be enriched. We can obtain an optimal ratio for mixing the above several oils by studying their effects and roles. This paper explored the inhibitory effects of peony seed oil, soybean oil, and rapeseed oil on α-amylase activity and α-glucosidase activity, and their optimal ratios were determined by a one-way test and response surface method. The results showed that the optimal ratio was peony seed oil: soybean oil: rapeseed oil = 60:27:13. The results provide specific technology and reference for the development and utilization of peony and provide a particular theoretical basis for the development of hypoglycemic drugs or health food.
