Abstract: This paper mainly studied the rheological properties of Artemis sphaerocephala Krasch gum. The results showed that the Artemis sphaerocephala Krasch gum is a kind of thixotropy. Apparent viscosity increased with the increase of concentration. The rheological properties followed the Herschel - Bulkey model. Its apparent viscosity changed a little with temperature and pH. The addition of salt, such as NaCl and GaCl2, affected apparent viscosity of Artemis sphaerocephala Krasch gum. Artemis sphaerocephala Krasch gum solutions exhibits typical“ weak gel” properties by small strain oscillatory measurements.

Key words: Artemis sphaerocephala Krasch gum, static rheological, dynamic rheological, apparent viscosity
