The extract is made from dry toad skin and is prepared by the technologies of poaching, column chromatographic separation, eluting, condensing,drying, etc. The invention effectively removes useless substances (impurity) in the extract, is enriched in effective component and achieves the goals of improving the curative effect and reducing the toxic and side effects.

The invention belongs to the field of the utilization of bast fiber and particularly relates to a new pulping raw material of rhus chinensis twig, a steam-explosion pulping process and a comprehensive utilization method thereof. The process comprises the steps of: poaching and separating to obtain barks and trunks; carrying out steam explosion on the barks; washing and then carrying out beating, bleaching and papermaking on the fiber raw materials; measuring the strength of the paper after carrying out the papermaking, wherein the strength of the obtained paper is superior to that of corrugated paper; separating and purifying the washing liquid to respectively obtain flavones and tannin substances; and finally clamping or briquetting the trunks. As the rhus chinensis twigs are used for pulping and papermaking via steam explosion, the industrial cost is reduced, cleanliness and environment protection are ensured, and functional components can be extracted; and the comprehensive utilization of the rhus chinensis twigs are realized by clamping and briquetting the trunks. Through the process, a new raw material is found for the field of papermaking, a new approach to the high-value utilization of the rhus chinensis is created and a new thought is provided to the comprehensive utilization of the rhus chinensis resources.

The invention relates to a method for germinating Araliaceae seed and keeping Araliaceae seed fresh. Wherein, it comprises (a), collecting seed at September while berry is black; (b), adjusting seed that first stacking collected seeds for 3-5 days then braking seeds via rolling method when stacking 3-5 days, poaching, taking out, drying, removing bore hole, and weighting; (c), treating seeds that adding activol to prepare the seed emerge solution whose density is 50-100mg / kg, and emerging the adjusted fresh seed in emerge solution for 1-2 hours, taking out and washing with water, and drying to make the humidity at 50-55%; mixing seed and sand uniformly, and using carbendazol and atomizing to disinfect, and making the humidity at 45-55%; putting it at 10-17Deg. C, after 20-60days, putting it at -1-5Deg. C for 40days, until seeding. The invention has short time and low cost.
