Abstract: Artemis sphaerocephala kraschen’s gum was tested by concentric cylinder viscometer. The result showed that A.S.kraschen’s gum was Thixotropic pseudroplastic(time-dependent fluid) at 1%～1.75%, and pseudroplastic(time-independent fluid) at 0.5%. Temperature and pH had no effect on viscosity of the gum fluids.
