The method comprises the following steps that 1), triennial oil Paeonia suffruticosa Andr. paeonia ostii seedlings which are consistent in growth vigor and free of plant diseases and insect pests are selected in October to be cultivated; 2), the paeonia ostii seedlings are cultured at room temperature until May of the next year, and water management is carried out during the period; and 3), the methyl jasmonate is sprayed to the oil Paeonia suffruticosa Andr. once every 3 days, and the methyl jasmonate is sprayed twice in total, and the drought-resistant oil Paeonia suffruticosa Andr. is obtained. According to the method for improving the drought resistance of the oil Paeonia suffruticosa Andr. by adopting methyl jasmonate, after the methyl jasmonate is adopted for induction treatment, the net photosynthetic rate, the transpiration rate, the intercellular CO2 concentration, the stomatal conductance, the free proline content and the solublesugar content in leaves are in the increase, the malondialdehyde content, the chlorophyll a content, the chlorophyll b content and the carotenoid content are in the decrease, the net photosynthetic rate of the paeonia ostii leaves is increased, the damage of drought stress to the Paeonia suffruticosa Andr. is reduced, and the drought stress resistance of the paeonia ostii is enhanced.

Externally applied traditional Chinese medicine composition, preparation and preparation method thereof capable of inhibiting skin non-enzymatic glycosylation
ActiveCN112472780BEnhanced inhibitory effectThe degree of redness increasesCosmetic preparationsToilet preparationsFacial skinFibroblast
The invention discloses an external Chinese medicine composition with the effect of inhibiting skin non-enzyme glycosylation. The Chinese medicine composition is made of the following raw materials in proportions by weight: 10-30 dried tangerine peel, 10-30 dried licorice, Perilla 10-30, Cardamom 10-30, Tsaoko 10-30. 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.

Preservation method for picked fruits and vegetables
ActiveCN114711287AGuaranteed hardnessReduce yellowingFood processingClimate change adaptationNutritionPropanedial
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.
