Paeonol microemulsion preparation and preparation method thereof

The invention relates to the medical technical field, in particular to a paeonol micro-emulsion preparation and a preparation method thereof. The paeonol micro-emulsion preparation consists of components with the weight percentage as follows: 0.1 percent to 2 percent of paeonol, 10 percent to 25 percent of surfactant, 5 percent to 30 percent of cosurfactant, 5 percent to 15 percent of oil phase and 40 percent to 70 percent of deionized water. The mouse percutaneous experiment in vitro shows that the paeonol micro-emulsion prepared by the invention has obviously higher capacity of penetrating through the horny layer than the saturated aqueous solution of paeonol (p is less than 0.05), and the paeonol micro-emulsion can penetrate into the skin deeply to take curative effect within a short time and also has certain sustained and controlled release function. At the same time, the paeonol micro-emulsion improves the solubility of the paeonol obviously, increases the drug loading quantity of the preparation and reduces the drug administration times and the dosage. The paeonol micro-emulsion preparation has simple preparation method and uniform grain diameter of the preparation, has the advantages of being safe, stable and efficient and, can be used for preparing dermal medication preparation or cosmetic.

Method for improving germination rate and survival rate of sophora alopecuroide seeds and sophora alopecuroide seeds

The invention discloses a method for improving the germination rate and the survival rate of sophora alopecuroide seeds of wild medicinal plants and sophora alopecuroide seeds and belongs to the technical field of seed culture. The method comprises the following steps that: firstly 80-98% sulfuric acid is adopted to soak the seeds for 1-1.5 hours, then more than 95% alcohol is adopted to soak the seeds for 18-30 seconds, and then a sodium hypochlorite solution with the active chlorine content of being 3-6% is adopted to soak the seeds for 3-8 minutes; and the concentrations and the treating time of reagents among all the treating steps have influences on the germination rate, the germination uniformity and the survival rate of the seeds respectively. The method disclosed by the invention has the beneficial effects that firstly the treatment with concentrated sulfuric acid is carried out to break and remove tissue structures of horny layers of outer skin layers and palisade layers of middle skin layers of the seeds, due to coverage to seed holes of mature seeds, the structures have influences on water absorption and oxygen entering into the seeds; and next, the alcohol is used for eliminating polar substances in the skin layer corroded by the sulfuric acid, so that the sodium hypochlorite solution is easy to be used for fully soaking the seed coats in the next step and kill microorganisms on/in the skin layer.
