Functional properties of dioscorin, a soluble viscous protein from Japanese yam (Dioscorea opposita thunb.) tuber mucilage Tororo.
A soluble viscous protein was purified from yam (Dioscorea opposita Thunb.) tuber mucilage tororo by chromatographic steps, and its functional properties were estimated. The purified dioscorin having the molecular weight of about 200 kDa exhibited high scavenging activities against hydroxyl radicals (IC50 = 195.1 microg/ml) and superoxide anion radicals (IC50 = 92.7 microg/ml). Moreover, it sho...
متن کاملPhysicochemical Properties of Dioscorea opposita Thunb. Solution Fermented by Lactobacillus bulgaricus
The present study was designed to determine the physicochemical properties of yam (Dioscorea) solution fermented by L. bulgaricus, the protective effect of fermented Dioscorea opposita Thunb. on stomach lesions, and the possibility of its application to fermented dairy products. When the concentration of yam increased, the pH increased in raw powder samples but not in extracted powder samples. ...
متن کاملCharacterization and Antihyperglycemic Activity of a Polysaccharide from Dioscorea opposita Thunb Roots
A polysaccharide DOTP-80 from Dioscorea opposita Thunb was obtained by using the method of acid water-extraction and ethanol-precipitation. After being purified by chromatography, the structure characteristics of DOTP-80 were established. Based on the calibration curve obtained with standard dextrans, the molecular weight of the polysaccharide fraction DOTP-80 was calculated to be 123 kDa. The ...
متن کاملextraction and acetylation of purified trypsin from bovin pancreas and study of some its physico-chemical properties
آنزیم تریپسین در شرایط قلیایی ناپایدار می باشد .و فعالیت پروتئولیتیکی تریپسین منجربه خود هضمی آن در جایگاههای خاصی می گردد. بنابر این آنزیمی با ناپایداری بالا محسوب میگردد. در سالهای اخیر موفق شدند که با ایجاد تغیرات شیمیایی با اضافه کردن فلزات خاص ، کلسیم و یا عمل استیلاسیون منجر به افزایش پایداری آنزیم تریپسین گردند. مطالعات در حال حاضر نشان می دهد که تریپسین استیله شده فعالیت آنزیمی خود را ...
15 صفحه اولAn effective method for extracting total RNA from Dioscorea opposita Thunb.
Dioscorea opposita Thunb., included in the genus Dioscorea of the family Dioscoreaceae, is an important herb with great edible and medicinal value. In this study, the total RNA from leaves of Lichuan Dioscorea opposita Thunb. was isolated by an improved Trizol method. The results showed that the RNA extracted by the improved Trizol method had good integrity, and the RNA could be used for down-s...
