To optimize the extraction technology of total triterpenoids from Verbena officinalis L..The content of total triterpenoids was determined by UV with oleanic as reference; Effects of concentration of extraction solvent,solid-liquid ratio,extraction time and extraction times by taking yield of total triterpenoids as the index,basis on this,extraction technology was optimized by orthogonal test.The optimum extraction technology were as follow:extracted 3 times with 35 times the amount of 80%ethanol,30 min each time.Under these conditions,yield of total triterpenoids from Verbena officinalis L.was 21.91 mg/g.This extraction process was stable and feasible,which provide the reference for the development and utilization of triterpenoids from Verbena officinalis.
