Abstract

The invention discloses a dendrobium officinale leaf extract with blood pressure reducing effect and application of the dendrobium officinale leaf extract. The dendrobium officinale leaf extract is prepared through the following steps: cleaning and drying the dendrobium officinale leaves; mechanically pulverizing; carrying out reflux extraction by a 0-30V% ethanol solution for 1-3 times, wherein the time of each reflux extraction is 1-3h and the dosage of each reflux extraction is 5-20 times of the medicine weight; combining the filtrates; recovering the ethanol; and carrying out vacuum concentration to obtain the dendrobium officinale leaf extract. The dendrobium officinale leaf extract can be used for preventing medicines or food for preventing and treating hypertension; the dendrobium officinale leaf extract relies on the dendrobium officinale leaves to develop the effects of the dendrobium officinale leaves, so that the new medicinal resources of the dendrobium officinale are expanded and the resource waste is decreased at the same time.
