RESUMO
A flavoring agent and a suspension agent were prepared for extemporaneous compounding. The stability of the two agents before and after drug loading was investigated, and the taste of the suspension after extemporaneous compounding was evaluated by electronic tongue technology. The two agents remained stable under the conditions of influence factor test, accelerated test and long-term test. The appearance properties of the two agents did not change. The relative density of the flavoring agent was maintained at 1.053-1.075, and the pH was stable at 4.2-4.5. The relative density of the suspension agent was maintained at 0.999-1.022, and the pH was stable at 4.0-4.5. Seven kinds of drugs, including warfarin sodium tablets and spironolactone tablets, were mixed with these two oral solvents, and the content uniformity and stability were detected respectively. The results showed that the preparations could be evenly dispersed and the physical and chemical properties were stable. The results of taste evaluation showed that in captopril group and chloral hydrate group, the flavoring agent had the best effect on taste correction. In warfarin sodium group, rifampicin group, spironolactone group, vitamin B1 group and vitamin B2 group, the blending agents had the best effect on taste correction.
RESUMO
Objective To study the effect of Alpinia officinarum Hance (A. officinarum) 80% alcohol extract on the primary dysmenorrhea. Methods A. officinarum 80% alcohol extract were enriched by macroporous adsorption resins. Female mice of primary dysmenorrhea model were established by oxytocin induction; the effects of A. officinarum 80% alcohol extract on primary dysmenorrhea were observed by body twist method; and the homogenate level of prostaglandin F
RESUMO
OBJECTIVE@#To study the effect of Alpinia officinarum Hance (A. officinarum) 80% alcohol extract on the primary dysmenorrhea.@*METHODS@#A. officinarum 80% alcohol extract were enriched by macroporous adsorption resins. Female mice of primary dysmenorrhea model were established by oxytocin induction; the effects of A. officinarum 80% alcohol extract on primary dysmenorrhea were observed by body twist method; and the homogenate level of prostaglandin F2α (PGF2α), prostaglandin E2 (PGE2) and Ca(2+) in the uterus were observed in oxytocin-induced female mice.@*RESULTS@#The writhing frequency of primary dysmenorrhea mice was significantly decreased after treatment of A. officinarum 80% alcohol extract and the level of PGF2α, PGE2 and Ca(2+) in mice uterus was significantly decreased (P < 0.05, P < 0.01) in groups of mice treated with middle and high dosage of A. officinarum 80% alcohol extract compared with that of model group.@*CONCLUSIONS@#These findings suggest that A. Officinarum 80% alcohol extract can significantly relieve primary dysmenorrhea.
