Abstract: The carbohydrate compound content i n the ripe fruits of Parthenocissus Tricuspidate Plach was measured accordingtotheimprovedcolorimetricmethodofO -ToluidineandHydrolysis methodofHydrochloricacid.Thelinear measuringranges werefrom0.02～0.50mg /ml.Theinterratingcoefficien twas0.9991,RSD2.93%andtherecore ry rate99.11%.The methodhas characte ristics of easly operationto,acute color showing,wellreappearing and resistant to disturbance of reduction substan ces,Both the whole carbohydrate and soluble carbohydrate content were m easured,So it was also adaptable to the measur ing of carbohydrate chemical compou ndcontent inwild plants.
