Abstract
Andrographis paniculata is a bitter herb used in Asian countries to treat inflammation. Andrographolide (AG) is a diterpenoid compound extracted from Andrographolide paniculata. It is the main active component of Andrographolide paniculata. However, due to its low solubility in water, its biological use is extremely low and it is not easily absorbed during cervical recovery, greatly limiting its application in edible beverages. In this study, emulsifiers and co-emulsifiers were used to miniaturize the andrographolide extracted solution and the process system was optimized by response surface methodology. The AG oil solution was a light yellow transparent liquid; the HLB value was 12.2, which met the requirements of self-emulsification to form O/W micro-emulsion after emulsification. The stability of the optimized AG oil solution showed that the appearance of the solution was light yellow, clear and transparent, and unchanged, and the drug content remained stable at normal temperature and natural conditions for 0, 1, 3 and 6 months.
