生物活性：Guar gum 是一种用于药物输送应用的多功能聚合物。Guar gum 具有增稠、乳化、粘合和胶凝特性，在冷水中溶解快，pH 值稳定性广，成膜能力强，生物降解性强，在众多行业得到应用。Guar gum 可以从 Cyamopsis tetragonolobus 种子的粉状胚乳中分离出来。Guar gum 可用作增稠剂、助悬剂等药用辅料。药用辅料或药用助剂，是指制药过程中使用的除药物成分以外的其他化学物质。药用辅料一般是指药物制剂中的非活性成分，能提高药物制剂的稳定性、溶解性和加工性。药用辅料还影响合并用药的吸收、分布、代谢和消除 (ADME) 过程^[1][2][3]。

Guar gum is a versatile polymer for drug delivery applications. Guar gum diaplays thickening, emulsifying, binding and gelling properties, quick solubility in cold water, wide pH stability, film forming ability and biodegradability, it finds applications in large number of industries. Guar gum can be isolated from the powdered endosperm of the seeds of the Cyamopsis tetragonolobus. Guar gum can be used as an excipient, such as thickener, suspending agent. Pharmaceutical excipients, or pharmaceutical auxiliaries, refer to other chemical substances used in the pharmaceutical process other than pharmaceutical ingredients. Pharmaceutical excipients generally refer to inactive ingredients in pharmaceutical preparations, which can improve the stability, solubility and processability of pharmaceutical preparations. Pharmaceutical excipients also affect the absorption, distribution, metabolism, and elimination (ADME) processes of co-administered drugs^[1][2][3].
