The present invention relates to an extraction and separation method of caper spurge seed sterol. Said method successively includes the following steps: (1), extraction: using low-polarity solvent to make refluxing extraction; (2), column chromatography: respectively collecting fraction containing caper spurge seed sterol and collecting fraction containing no caper spurge seed sterol, making the fraction containing caper spurge seed sterol undergo the processes of concentration and crystallization, concentrating the fraction containing no caper spurge seed sterol and recovering solvent, and discarding concentrated paste; (3), crystallization: eluting the fraction containing caper spurge seed sterol, making distillation and concentration at normal pressure, and crystallizing for 24-3hr at room temperature, filtering to obtain crystal crude product; (4), recrystallization: heating and dissolving said crystal crude product in low-polarity mixed solvent, filtering to obtain crystal product.

The present invention provides ingenol and a preparation method therefor. The method comprises: by taking euphorbia lathyris seeds as raw materials, obtaining the ingenol through recovery, extraction, hydrolysis reaction and silica gel column chromatography. According to the ingenol and the preparation method therefor, types off solvents used in the whole preparation process are less; both an extraction solvent and an extracting solvent are methanol; the solvent can be reused, so that the production cost is reduced, and the production process is simplified; the hydrolysis reaction of an ingenol esterified compound is performed by use of a strong base; by virtue of this reaction, an esterified compound of the ingenol can be converted into the ingenol, so that the separation process is simplified; and the ingenol with purity higher than 98% can be acquired through silica gel column chromatography for separation, so that use of a high-pressure reversed phase chromatography system is avoided, and the separation conditions are simplified. By use of the preparation method provided by the present invention, industrial preparation of the ingenol can be achieved, the preparation yield is high, and the product purity is high.

A formulation for the mask powder comprises 3 to 10 grams of ginseng, 3 to 15 grams of rhizome polygonati, 6 to 15 grams of radix asparagi, 3 to 10 grams of rhizome typhonii, 3 to 10 grams of angelica dahurica, 6 to 15 grams of angelica, 3 to 10 grams of white stiff silkworm, 6 to 15 grams of fructus xanthil, 3 to 10 grams of bletilla, 6 to 15 grams of white gourd seed, 3 to 15 grams of gingko leaf, 3 to 10 grams of fragrant solomonseal rhizome, 3 to 10 grams of puncturevine, 3 to 10 grams of euphorbia lathyris, 1 to 6 grams of pearl powder, 1 to 6 grams of litharge, 3 to 10 grams of mint, 1 to 3 grams of human placenta, 3 to 6 grams of cinnamon, 3 to 10 grams of tasselblower, 3 to 10 grams of leucophanite, 1 to 3 grams of borneol, 10 to 30 grams of green bean powder, and 3 to 10 grams of honey-fried licorice root.

The invention relates to an active material extracted from euphorbia lathyris and application thereof, and belongs to the technical field of biological pesticides. The active material extracted from euphorbia lathyris is characterized in that a method for obtaining the active material comprises the following steps of: a, cleaning collected branches or leaves of the euphorbia lathyris by tap water, putting the cleaned branches or leaves in an oven for roasting at the temperature of 50 DEG C for 10 hours, cutting 10g of dried branches or leaves into pieces, and putting the cut branches or leaves in a triangular flask, soaking the branches or leaves by 80 percent ethanol, wherein the time for the first soaking extraction is 4 hours, and the time for the second and the third soaking extractions is 12 hours and 24 hours respectively; b, mixing extraction solution obtained by the extractions at the third time, condensing the obtained solution until the solvent is vaporized to obtain coarse extracts of the branches or leaves, dissolving the coarse extracts in methanol to prepare the solution of which the concentration is 0.1g / ml, and putting the obtained solution in a refrigerator for later use. The active material can be used for preparing a biological reagent of killing B.xylophilus. The active material has the advantages of low cost, simple and convenient preparation method, high efficiency and low toxicity, which can be used for preparing the biological reagent of killing B.xylophilus.
