Abstract: The factors which affect the jellification of the ficus pumila (L.) Gum,such as pH,temprature and the influence of the Ca2+ are studied in this paper.It confirms the pH range ,the most suitable temperature to maintain the most proper colloidal state,and the influence of Ca2+ in different pH on the jellification of the ficus pumila (L.) Gum.

Key words: ficus pumila, ficus pumila (L.) gum, jellification
