Content Determination of Total Flavonoids in and Non-medicinal Parts
Objective: Studying the best extraction method of flavonoids and its change in various parts of Dioscorea opposita Thunb to take full advantage of yam resources and to avoid wastage. Method: Using ethanol ultrasonic extraction method and orthogonal experimental design to select the best extraction method of total flavonoids and determing the content by spectrophotometry. Result: The extraction method of total flavonoids in D. opposita is: ultrasonic extraction with 15 mL of 95% ethyl alcohol 3 times
each time 45 min. The leaf flavonoid content is the highest
followed by skin raw yam flour
cane
yams Bubil. Conclusion: Total flavonoid content in D. opposita in different parts were significantly different.
