Abstract: Baekho Silver Needle and Xiakucao were used as raw materials,sensory evaluation was taken as index,andraw materialratiobrewing temperature,brewingtimeand flushing volume were taken as theinvestigation factors,the processwasoptimized bysingle factor testandorthogonal test,andthe contents of protein,flavonoids, polysaccharides and tea polyphenols were determined. The results showed that the optimal formula and brewing process of Prunella vulgaris tea bags were as follows: Xiakucao 40 mesh,Baekho Silver Needle 50 mesh,Baekho Silver Needle : Xiakucao =2.0:1.0(g:g) , brewing temperature 90°C , brewing time 8min , and brewing volume 250mL . The protein content was 6.86g/100g ,the flavonoid content was (23.6±0.02)mgcdotg-1 , the polysaccharide content was 11.4% , and the tea polyphenol content was 17.54mg?g-1
