The invention discloses
melaleuca alternefolia total flavone extract and a preparation method thereof. The preparation method comprises the following steps of extracting
essence oil from the
melaleuca alternefolia
branch and leave by
water vapor, performing
ethanol heating and refluxing extraction, reducing the pressure to recycle the
ethanol, concentrating to remove the
ethanol flavor, separating and purifying by macroporous absorption resin, and
drying; measuring the content of total flavone in the
melaleuca alternefolia by adopting an
ultraviolet-visible
spectrophotometry method. The preparation method has the advantages that the method is accurate and stable, the operation is simple, the requirement of industrial production is met, and the quality of the melaleuca alternefolia total flavone extract can be effectively controlled; the content of total flavone in the melaleuca alternefolia total flavone extract can reach more than 50 percent, the
toxicity is little, and the pharmacological functions of resisting
inflammation, inhibiting
bacteria, alleviating pain, resisting
allergy, resisting oxidizing and the like are realized; the preparation method is reasonable and stable, the
production cycle is short, the preparation method is suitable for industrial production, the important meaning is realized on the deep development and utilization of melaleuca alternefolia resources, and the development prospect is good.
