为了综合利用好石阡苔茶资源，优化石阡苔茶咖啡碱的工艺条件，试验以咖啡碱提取率为考察指标，考察煮沸时间、茶汤比、沉淀剂浓度、萃取次数对咖啡碱提取的单因素试验和正交试验。结果表明，石阡苔茶水提正交试验最佳工艺条件为萃取2次，沉淀剂浓度为0.2 mol/L，茶汤比为1∶60 g/mL，煮沸15 min。优选得到的工艺条件简便、安全、稳定和可行。在此条件下，测得石阡苔茶咖啡碱水提的得率为1.92%。

To better comprehensive utilization Shiqian moss tea resources , optimize extraction process conditions in Shiqian moss tea caffeine,the yield of caffeine as index in experiment. Assay determination is conducted by apply of extraction time, solid-liquid ratio, precipitator concentration, extract times on caffeine extraction rate is determined through single factor and orthogonal experiment. It turned out that , the optimal extraction condition of Shiqian moss tea is twice extract, precipitator concentration 0.2 mol/L, solid-liquid ratio 1∶60 g/mL, extraction time 15 min. The process conditions by optimize was simple, safe, stable and feasible.In this conditions, the extraction rate of Shiqian moss tea caffeine can reach to about 1.92%.
