STUDY OF DRYING METHODS AND EXTRACTION METHODS ON PHENOLIC CONTENT
Medicinal plants contain secondary metabolites, one of which is phenolic compounds. Phenolic compounds have many pharmacological activities including antioxidant, antidiarrheal and antibacterial. This study aims to determine the effect of drying method and extraction method on phenolic content. The research is compiled based on the journals that have been collected, namely national and international journals. The results showed that the drying method and the extraction method affected the phenolic content. Obtaining the highest phenolic content will provide optimal pharmacologic activity provided by optimal drying and extraction methods. The results of the literature search show that the simplicia drying method and the extraction method affect the % yield of extracts from medicinal plant simplicia. In addition to % extract yield, the simplicia drying method and extraction method also affected the average content of total phenol in medicinal plant.
