摘要： A Macadamia integrifolia whitening extract and a preparation method thereof are disclosed. The preparation method includes: S1: carrying out a hot extraction on a crushed Macadamia integrifolia green peel using an ethanol solution as an extraction solvent to obtain a crude green peel extract; then enzymatically treating the crude green peel extract using a snailase to obtain a enzymatic hydrolysate; finally extracting the enzymatic hydrolysate using a petroleum ether, and taking an aqueous phase to obtain a green peel extract; S2: carrying out a hot extraction on crushed Sichuan lovase rhizome decoction pieces using an ethanol solution as an extraction solvent to obtain a Sichuan lovase rhizome extract; S3: dispersing the green peel extract and the Sichuan lovase rhizome extract in water to obtain a whitening extract.

摘要： The present disclosure relates to the technical field of nut-derived fruit oil preparation, in particular to a method for extracting palmitoleic acid from Macadamia integrifolia and use thereof. In the method for extracting palmitoleic acid from Macadamia integrifolia, a fruit oil of the Macadamia integrifolia is purified by vacuum distillation, and an antioxidant is added during the vacuum distillation. A preparation method of the antioxidant includes the following steps: extracting a pulverized Macadamia integrifolia green peel using ethanol by heat reflux to obtain a green peel extract; extracting the green peel extract using petroleum ether, and then using ethyl acetate; collecting an ethyl acetate layer to obtain the antioxidant. The method can avoid easy oxidization and deterioration of oil during extracting and enriching the palmitoleic acid, and can enrich the palmitoleic acid in the fruit oil of the Macadamia integrifolia by not less than 3 times.

摘要： The present disclosure relates to the technical field of Gastrodia elata planting, in particular to an organic planting method of G. elata, including the process of mycelia colonized material preparation: cutting a branch of Quercus acutissima into bars; cutting out fish scale openings on the bars to obtain bars with the fish scale openings; successively soaking the bars with the fish scale openings in boiling water and a growth-promoting solution to obtain bars after growth promotion treatment; and putting Amillariella mellea spawns and an inoculation substrate into each fish scale opening of the bars after the growth promotion treatment to obtain a mycelia colonized material. The growth-promoting solution and the inoculation substrate are prepared by treatment of fresh G. elata stalks with Bacillus pumilus and hot-dip extraction treatment in ethanol.
