Study on Supercritical Extraction of Volatile Oil from Radix Notopterygii and Its Inhibition of Tyrosinase Activity

Study on Supercritical Extraction of Volatile Oil from Radix Notopterygii and Its Inhibition of Tyrosinase Activity The extraction process of volatile oil from Radix Notopterygii was optimized by supercritical fluid extraction, and its whitening activity was studied. On the basis of single factor experiment and taking the yield of extract as the evaluation index, the […]
