Fig. 1From: Evaluation of wound healing and anti-inflammatory activity of the rhizomes of Rumex abyssinicus J. (Polygonaceae) in miceCalibration curve for estimating hydroxyproline concentration: tissue obtained from excision wound was hydrolyzed in 6 N HCl for 24 h at 110 °C in sealed glass tubes. The hydrolysate was neutralized to pH 7. One ml of the supernatant solution was taken from each tissue hydrolysate and the absorbance was readBack to article page
