Yu Ju Effervescent Preparation Process And Quality Standards

Yuju effervescent tablet is made up of Oroxylum indicum, Chrysanthemun indicum, Paeonia lactiflora Pall, and Borneolum, which is used to cunt tickle, causalgia, mildew, colpitis etc. This paper studies the pick-up technics and quality standard of the Yuju effervescent tablet. A large amount of experimental work was done in this thesis.At first, the extract of Oroxylum indicum, Chrysanthemun indicum, Paeonia lactiflora Pall, were studied. According to the reports, during the course of extract, a lot of factors disturbed, such as water, time and decoction degree etc. Through a series of orthogonal tests, we found out that the better extractive condition was ten times water, extracting three times and one hour every time. The best way of deposition by alcohol is that the proportion is 1. 10 with 70percent alcohol as much as the weight of the liquid.Second, the moulding condition was studied. It is made certain that the most suitable moulding direct ions: the proportion of the tartaric acid and sodium bicarbonate is 1: 1 and of the medication and effervescent materials is 2: 1.At last, quality control of Yuju effervescent tablet's resource and finished product was also studied. It was provedthat the quality of resource and finished product could be controlled. At the same time, the production technology was effective and feasible.
