This research aimed to optimize the extraction condition, and to identify and investigate the bioactivities of triterpenoids from Crataegus cuneata. The optimum extraction conditions for recovering triterpenoids from hawthorn were ultrasound‐assisted extraction with 80% methanol at 30°C, 400 W for 20 min, which resulted in the recovery of total triterpenoids of 28.47 mg/g dry material. Further isolation...
The objective of the present experiment was to assess the protective activity of sorghum vinegar (V) and mei vinegar (MV) and its alkaloids by evaluating its antioxidant, anti‐mutagenic, and hypouricemic activities. The acetic acid concentration, metallic ions like calcium (Ca), copper (Cu), iron (Fe), sodium (Na), potassium (K), zinc (Zn), magnesium (Mg), manganese (Mn), and alkaloid contents (β‐carbolines)...
