抄録

Mumefural is a component of Japanese apricot fruit juice concentrate, which has been used as a traditional nonofficial medicine in Japan, and was reported to have an activity to improve the blood fluidity. For quantitative analysis of mumefural, water extract of the fruit-juice concentrate was loaded on a cartridge column for solid-phase extraction (Oasis^® HLB, Waters) and eluted with 20% acetonitrile. Following HPLC analysis on a XTerra^TM MS C₁₈ column (Waters) by linear gradient elution with acetonitrile-20mM sodium phosphate buffer (pH 2.3) gave a peak of mumefural at 280nm, from which area quantity of the compound could be elucidated based on the calibration curve obtained in this work. Mumefural content of 4 Japanese apricot fruit-juice concentrates was determined as 1.41mg/g, 0.361mg/g, 11.5mg/g, and 3.82mg/g, respectively, by this method. Accurate molar absorption coefficient (ε) of mumefural was determined as 1.78×10⁴ (λ_max 282nm, water). Since mumefural is highly hygroscopic amorphous solid, it is difficult to weigh out an accurate quantity for preparation of a standard solution. Molar absorption coefficient of mumefural is, therefore, useful to calibrate the concentration of the standard solution for HPLC analysis.
