The external application of the traditional Chinese medicine extract of the present invention has better inhibitory effect on the early and mid-stage products of non-enzymatic glycosylation. The inhibitory effect at the concentration of 2% is obviously better than that of the positive drug aminoguanidine. The extract of the present invention has a better inhibitory effect on the final product of fibroblast malondialdehyde MDA in the lipid peroxidation reaction at a low concentration. Experiments on volunteers showed that the facial mask prepared from the extract of the present invention significantly increased the degree of redness and decreased the degree of yellowness of the facial skin, had better anti-yellowing effect, and improved the luster of the skin to a certain extent.

Method for improving drought resistance of oil paeonia suffruticosa by adopting jasmonic acid

The invention discloses a method for improving the drought resistance of oil paeonia suffruticosa by adopting jasmonic acid. The jasmonic acid is adopted to induce the oil paeonia suffruticosa to generate the drought resistance. The method comprises the following steps that 1), triennial oil paeonia suffruticosa seedlings which are consistent in growth vigor and free of plant diseases and insect pests are selected in October to be cultivated; 2), the triennial oil paeonia suffruticosa seedlings are cultured in a greenhouse at room temperature until May of the next year, and normal water management is carried out during the period; and 3), the jasmonic acid is sprayed to the whole oil paeonia suffruticosa plants until the upper and lower surfaces of leaves drip the jasmonic acid, the jasmonic acid is sprayed once every 3 days and is sprayed twice in total, and the drought-resistant oil paeonia suffruticosa is obtained. According to the method for improving the drought resistance of theoil paeonia suffruticosa by adopting the jasmonic acid, in the post-growth stage of the oil paeonia suffruticosa, the exogenous jasmonic acid with different concentrations is adopted for induction, the osmotic regulation substance content and the photosynthetic pigment content (the chlorophyll a content, the chlorophyll b content and the carotenoid content) of the oil paeonia suffruticosa under drought stress are remarkably improved, the malondialdehyde content is reduced, the cell membrane lipid peroxidation degree is reduced, photosynthesis of the paeonia ostii is promoted, and the defense capability of the paeonia ostii on drought stress is enhanced.

Preservation method for picked fruits and vegetables

The invention belongs to the technical field of fresh-keeping, and particularly relates to a fresh-keeping method for picked fruits and vegetables. According to the method, the picked fruits and vegetables are sequentially subjected to cold shock treatment and packaging treatment, and the gas environment in the package can be changed, so that the consumption of nutrient substances caused by respiration is reduced, the loss of water is reduced, the hardness of the picked fruits and vegetables is maintained, the increase of the weight loss rate is slowed down, and the oxygenolysis of chlorophyll is delayed, and the original color of the picked fruits and vegetables is maintained to a great extent; the fruit and vegetable fresh-keeping agent is capable of delaying yellowing of fruits and vegetables, inhibiting physiological metabolic activities of the picked fruits and vegetables, delaying consumption of soluble solids of the fruits and vegetables, inhibiting membrane lipid peroxidation, reducing accumulation of malonaldehyde and inhibiting concentration change of volatile organic compounds, has a synergistic effect on physicochemical, nutrition and flavor quality of the picked fruits and vegetables, and improves the fresh-keeping effect of the picked fruits and vegetables.
