개요Protocatechualdehyde is extracted from roots of the common traditional Chinese medicine Salvia miltiorrhiza Bge, which was harvested in autumn for better quality. Take root and remove stems, leaves and fibrous roots, then dry it. Most of them are wide, and they are mainly cultivated in recent years. South Salvia and Gansu Salvia are also widely used. Besides, there are a variety of sibling plant roots used as Salvia miltiorrhiza in Yunnan. Now, the existence of protocatechualdehyde has been found in variety of herbs, for example, in the leaf of Stenoloma Chusanum (L.) Ching and Ilex chinensis Sims.

역사In the 1940s, the research was conducted overseas to obtain protocatechualdehyde form herbs. In 1972, the chemical group of Chinese herbal medicine in Nanjing College of Pharmacy systematically studied chemical composition in purple flower holly leaf and separated six monomers including protocatechualdehyde. Then they compared the effect of protocatechualdehyde, Salvia miltiorrhiza injection and hairy holly root injection, in which protocatechualdehyde is the most effective in increasing coronary sinus flow. Further experiments examined that protocatechualdehyde can increase coronary flow and improve coronary circulation, so it was called after perhexiline. Further clinical observation indicated that protocatechualdehyde has effect on coronary heart disease. The graduates of Nanjing College of Pharmacy in 1975 extracted, separated, isolated, and identified protocatechualdehyde in Salviamiltiorrhiza during the internship in Nanjing Municipal Hospital and studied its distribution, excretion, and toxicity in animals for clinical rational drug usage
