Lumbar muscle strain is the chronic injury of the soft tissue of the lumbar muscles, fascia and ligaments, low back pain is the most common disease, also known as functional low back pain, chronic lower lumbar strain, Chinese medicine is often referred to as kidney lower back pain. Long-term repeated excessive hip motion and overload can easily lead to lumbar muscle strain. Therefore, the disease is very common in athletes, the elderly, and the population has long been engaged in office work, has seriously affected the normal life and work of the people. Strong the waist Zhuanggu cream contains Eucommia, Dipsacus, fenugreek, papaya, Achyranthes, Panax, Guizhi, Song Festival Bawei herbs. Eucommia herbs have liver or kidney, strong bones effect Indications kidney back pain. The Dipsacus herbs have liver or kidney, strong bones and muscles effect, attending Yaoxisuanruan the flutter injury. Notoginseng for Sanyu bleeding, swelling and pain. The strong lumbar bone paste can be effective in the treatment of kidney back pain, muscle strain, and the old soft tissue injury. But as rubber, ointments, it exists the shortcomings of the viscous differential is too large, the skin compatibility, impervious breathable. The use of hydrophilic polymer material as the matrix material, prepared strong waist Zhuanggu in Papua paste. The cataplasm suitable viscous, biocompatible, not sensitized. In addition, the quality of the the strong waist Zhuanggu Babu paste establish a preparation of ginsenoside Rg1 HPLC method. The main results are as follows: (1) examine the quality of the different sources of medicinal, medicine extract extraction process, to have anointed rate and the content of the extract ginsenoside Rg1 as index, to determine the optimum extraction process conditions, and the process repeated verification. The herbs have cream in the extraction process was 28% to 32% (relative density of 1.25 to 1.30 (80 ° C)) per gram of extract containing approximately 2.215 mg ginsenosides Rg1. (2) by orthogonal design experiments and prescription optimization experiments, screened prescription craft of the appropriate strong waist Zhuanggu Babu cream, the basic accessories proportion: 5.0% sodium polyacrylate; crosslinker was 0.3%; filler 2.0%; tackifier -1 is 2.0%; tackifier -2 4.0%; tackifier -3 0.5%; pH-adjusting agent is 0.1%; crosslinked modifier is 0.02%; excipient is 2.0 %; humectant is 30%. By prescription prepared sticky appropriate skin follow with good Babu cream. (3) in accordance with the provisions of the 2005 edition of Chinese Pharmacopoeia, cataplasm adhesion performance, given the type and amount of gypsum-bearing checking results show that the Bab cream initial tack can be stuck on the 14th ball, 180 ° peel strength of up to 0.9 N. 100 cm2 on the amount of gypsum to 8.58 g. Shaping, repeatedly exposing paste. (4) establish a the ginsenoside Rg1 Determination in the a strong waist Zhuanggu Papua paste HPLC method. The results show that the blank matrix accessories and solvent has no effect on the determination of the drug, ginsenoside Rg1 good linear relationship between concentration and peak area in the range of 25.2 ~ 252.0μg · mL-1 solution stability, high precision, with an average recovery rate of 99.51%, and good reproducibility. The same batch and batch-to-batch measurement results show that the formulations of the drug content, drug content uniformity.
