Vitexin is a natural flavonoid compound extracted from Vitex leaves and Vitex seeds. However, because the plant Vitex is still in the wild, it is common in southern mountainous areas but grows scattered. While cultivated Vitex is rare, not alone large-scale plantation.
Harvested The Vitex chinensis leaves and Vitex sylvestris are all mixed with Vitex sylvestris, Vitex sylvestris and Vitex sphaerocarpa, and they are not a single Vitex species.
Therefore, pure vitex leaves and vitex seeds are relatively inadequant. The collected vitex leaves are basically used for distillation to refine vitex oil.
This has led to plant extraction manufacturers to give up the high content Vitex source, and instead use hawthorn leaves to extract vitexin. Extract vitexin from the total flavonoids of hawthorn leaves through extraction, separation, purification and other processes, and finally makes a freeze-dried preparation.
At present, many plant extract manufacturers are producing vitexin plant extracts, in addition to vitex extract, such as vitex extract, hawthorn leaf extract, etc., they all use vitexin (Vitexin) as an effective ingredient indicator In production, the products are also sold to customers based on vitexin. The content index of vitexin in vitex vulgare and hawthorn extract is basically only about 5% vitexin.
At present, vitexin is mainly used to treat cardiovascular diseases, and the purity of vitexin generally requires >98% (HPLC). Vitexin for injection has been used in clinical medicine. The main function of vitexin is to promote blood circulation, remove blood stasis, regulate qi and channel. It is used for chest obstruction caused by blood stasis, chest tightness, breathlessness, precordial tingling, palpitations, forgetfulness, dizziness and tinnitus.
