Abstract

The invention relates to the technical field of dracocephalum moldavica extracts and provides a dracocephalum moldavica extract and a preparation method and application thereof. The mass percentage of total flavone in the dracocephalum moldavica extract is 50.3-58.5%. The content of total flavone in the dracocephalum moldavica extract is substantially increased compared with the content of total flavone in an existing dracocephalum moldavica extract. The high dose group and the medium dose group of the dracocephalum moldavica extract have a better curative effect on myocardial ischemia compared with heart-benefiting BaDiRanJiBu subgrains. It is shown that the dracocephalum moldavica extract has a certain protective effect on myocardial ischemia injuries of rats. The dose of the medium dose group of the dracocephalum moldavica extract and the dose of the low dose group of the dracocephalum moldavica extract are 25% and 12.5% of the taking dose of the dracocephalum moldavica extract respectively, and therefore the dose is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of orchid orchid extract, and relates to an orchid orchid extract and its preparation method and application.
