Geo-authentic Medicinal In Shan Dong-Ren-Fructus Trichosanthis's Quality Inspect

OBJECTIVE Fructus Trichosanthis is an important Geo-authentic medicinal material in Shan Dong.It is one of the three Traditional Chinese Medicines on GAP studies in Shan Dong from Ministry of Science and Technology of China.Ren-Fructus Trichosanthis is an excellent farmhouse clutivars in Shan Dong.lt is also the chiefly variety of the study on GAP.This special subject probed into the pharmacognosy characters of Ren-Fructus Trichosanthis and the relation between different processing methods and the water,ash contents.lt is determined the contents of heavy metal and presticide remainder quality.lt is also determined the contents of the extracts and carbohydate components,and emphasisly invented the IR fingerprint of Ren-Fructus Trichosanthis .The purpose of this thesis is to provide scientific data to establish GAP criteria and system of the quality evaluation of Ren-Fructus Trichosanthis.MEHTODS The water,ash and extracts contents of Ren-Fructus Trichosanthis were measured according to the Pharmacopoeia of the Peple's Republic of China (2000 Edition).Methods of Pharmacoghosy,Scanny electron microscope,Scanning confocal microscope were used to study the quality of appearance and character of issue.Atomic absorption spectrophotometry was adopted to determine the contents of heavy metal.Methods of GB/T5009.19-1996,GB/T5009.20-1996 presticide remainder quality's determination was used to measure the presticide remainder quality.Anthrone colorimety method was adoped to measure the contents of carbohydate components.The FT-IR was used to invent the fingerprint of the Ren-Fructus Trichosanthis.RESULTS According to the pharmacognosy study of Ren-Fructus Trichosanthis,thegood appearance quality standard was established. According to the analysis and determination of water,ash,heavy metals, presticide remainder quality,extracts and carbohydate components,the results showed that the harvest period of Ren-Fructus Trichosanthis in Suptember was appropriate, the process of being dried in the oven was the best,the contents of heavy metal and presticide remainder quality were lower than domestic and foreign relative standards, the contents of the extracts and carbohydate components were as same as Tang- Fructus Trichosanmis's,and higer than Di- Fructus Trichosanthis's .According to the IR fingerprint,the discrimination of the true and the fake, and the quality evaluation of the inferior and the prior of the Ren-Fructus Trichosanthis could be carred out.The result proved that Ren-Fructus Trichosanthis was a high-quality,secure variety in Shan Dong.
