It is can' t guarantee the quality of Chinese traditional drugs completely

only by establishing the quality standard ofmedicinal material and decoction pieces. Now

we put forward a process control system (PCS) including every process and link in the production of Chinese traditional drugs by means of finding some problems and forming correlative measures. Based on 30 years for the systematic researches continuously on Trichosanthis Fructus

a commonly used Chinese traditional drug

we put forward a new concept of CPS on the quality of TrichosanthisFructus. This concept of CPS involves 10 process and links

such as plant variety

cultivation and propagation

pest control

fruit-bearing and fruit' s maturity

storage

pharmacist

chemical constitute

quality standard

limiting index

and circulation

by means of finding a series of problems and forming correlative measures in these process and links of Trichosanthis Fructus. This CPS can ensure the quality of medicinal material and decoction pieces of Trichosanthis Fructus systematically and comprehensively

improve the clinical curative effect of traditional Chinese medicine

and provide a model for the establishment of CPS for other traditional Chinese drugs.
