A biological active artificial saliva formulation containing flower mucilage from Ceylon Spinach ( Linn.).

Ceylon Spinach () is an edible perennial vine found in tropical Asia and Africa, known as vegetables containing mucilage. Its mucilage from flowers was extracted by microwaving and precipitated with 95% ethanol. Five artificial saliva formulations composing of mucilage from Ceylon Spinach, calcium chloride (CaCl), potassium chloride (KCl) and sodium fluoride (NF) were developed.

Physicochemical properties and biological activities of Thai plant mucilages for artificial saliva preparation.

Context: Plant mucilages can be found in various parts of several Thai plants, which can be used as thickening, moisturizing, and lubricating agents in artificial saliva formulations.

Objective: The objective of this study was to evaluate the physicochemical properties, biological activity, and cytotoxicity of Thai plant mucilages.

Materials And Methods: The mucilages from Thai plants were extracted by various processes (temperature and pH variation, microwave oven, steam, and Tris-HCl buffer extraction).
