Abstract:
Taking the fruits of wild Padus racemosa as test materials，the pigment solution were diluted as the ratio of 1∶20 and scanned in the range of 400～700 nm wavelength，in 532 nm had the biggest absorbance ratio.By orthogonal test of four factors that were ethanol concentration，temperature，liquid-solid ratio，extraction time，the best pigment extraction conditions from Padus racemosa Gilib.were determined.The results showed that the best pigment extraction conditions were 30% ethanol，extraction temperature 75℃，the liquid-solid ratio 1∶10，extraction time 90 min.
