The Preparation and Detection of Quality Standard about Houttuynia Spray

Abstract:

To explore of houttuyniae cordata quercetin best extraction solution and detection of quality standard about houttuynia spray. The study extracted quercetin from houttuyniae cordata using alcohol water extraction, ultrasonic extraction and supercritical CO2 extraction respectively, and then choosed the best solution to prepare sprays of houttuynia cordata. To conform the state pharmaceutical quality standards, quality standards were detected from four aspects in spray volume of each press, particle size, injection experiment and installation. The method of oultrasonic extraction was the best extraction method, and the concentrations of 70% ethanol was the most efficient extraction of quercetin.The technology of spray preparation is fast and feasible, and the method of content detection is reliable.These results showed houttuyniae cordata could develop spray and conform the state pharmaceutical quality standards.
