Objective:To research production technology of RHNXY and go on with quality detection of RHNXY

in order to optimize its production technology.Methods: By orthogonal design

the extraction technology with volatile oil of four crude drugs in RHNXY

and the extraction technology with water of gruffs and of eight crude drugs(including fritillariae thunbergii and so on) in RHNXY were optimized in the experiment

in order to be applied to practice.Results:(1) The extraction technology with volatile oil

which with decoction pieces added water in four times

soaked an hour

and extracted four hours

was the best one.(2) The extraction technology with water

which boiled twice and added water to eight quantities of original crude drugs at the first time and added water in eight times at the second time

lasting one and half hours every time

and separated with centrifugal

was the best one.Conclusions: Decreasing production cost and increasing quality of crude drugs were attained by optimigation production technology of RHNXY.
