    Journal: Zhong Yao Cai; 2006 Apr; 29(4):387-90. PubMed ID: 16913496.
    Abstract:
    OBJECTIVE: To study the extraction process of the total flavones content in Hibiscus manihot L. flower. METHODS: it was investigated that effect of ethanol concentration, extracting time, power of microwave oven and Solid/Liquid ratio (g/mL) on total flavones content using the orthogonal design. RESULTS: The optimum microwave-assisted extraction conditions included: ethanol concentration of 70%, extraction time of 30s, the power of microwave oven of 360w, solid/liquid ratio of 1 : 50 (g/ml) and granularity < or = 80 pore. CONCLUSION: There are broad possibilities for the extraction of the total flavones content from Hibiscus manihot L flower using Microwave-assisted technigue.
