    Abstract:Objective:To compare the total anthraquinones content in different parts of Rubia cordifolia L. in different degree charcoal and to offer reasonable experiment basis for establishing reasonable preparation technology and quality index.Methods:Acid hydrolysis, base display color and colorimetric method.Results:The content of anthraquinones is high. in thin Rubia cordifolia L. Its content decreases after parching into charcoal. With the temperature going up, the content reduces obviously.Conclusion:When cut Rubia cordifolia L. medicinal slice, we should distribute different parts. When parch it into charcoal, we should control temperature and time. ......
