Natural medicinal exudates such as gum arabic are high-molecular-weight natural polysaccharides and are highly soluble in water. The dissolved solutions of these exudates show viscous behavior and exhibit favorable emulsion stability. These exudates have been widely used not only as a medicinal additive, such as a coating agent for tablets and as an emulsifier and stabilizer in beverage and food products, but also for other industrial applications, such as paints and ink. Gum ghatti was originally used as an alternative to gum arabic due to its similar properties to those found in gum arabic. Gum ghatti has been used as a food additive due to its excellent emulsification properties. In this study, we obtained gum ghatti nodules and branches as botanical specimens, which were collected from the same harvesting area. Refined gum ghatti processed from the collected gum ghatti nodules was found to comply with the specifications set by the Joint FAO/WHO Expert Committee on Food Additives (JECFA) and also to be identical to commercially available gum ghatti products as a food additive. Component analysis of the refined gum ghatti samples revealed that they contain arabinose (34.0-38.0 %), galactose (21.0-24.6 %), mannose (5.3-7.9 %), xylose (0.8-1.2 %), rhamnose (0.8-1.2 %), and glucuronic acid (15.4-18.6 %) as constituent sugars, protein (2.7-3.6 %), moisture (4.9-8.3 %), and tannin (0.041-0.092 %). As a result of the investigation of collected branches as botanical specimens, they were identified as Anogeissus latifolia Wallich. Detailed observation of their morphological characteristics revealed that many crystal cells were aligned in the lengthwise section of branch specimens.
天然药用渗出物，如阿拉伯胶，是高分子量天然多糖，在水中高度溶解。这些渗出物的溶解溶液表现出粘性行为，并表现出良好的乳化稳定性。这些渗出物不仅广泛用作药用添加剂，如片剂的包衣剂，以及饮料和食品产品中的乳化剂和稳定剂，而且还用于其他工业应用，如油漆和墨水。由于其与阿拉伯胶相似的性质，因此最初使用 Gum ghatti 作为阿拉伯胶的替代品。由于 Gum ghatti 具有出色的乳化性能，因此被用作食品添加剂。在这项研究中，我们获得了 Gum ghatti 结瘤和树枝作为植物标本，这些标本是从同一收获区收集的。从收集的 Gum ghatti 结瘤中加工精制的 Gum ghatti 符合粮农组织/世界卫生组织食品添加剂联合专家委员会（JECFA）制定的规格，并且与商业上可获得的 Gum ghatti 食品添加剂产品相同。精制 Gum ghatti 样品的成分分析表明，它们含有阿拉伯糖（34.0-38.0％）、半乳糖（21.0-24.6％）、甘露糖（5.3-7.9％）、木糖（0.8-1.2％）、鼠李糖（0.8-1.2％）和葡萄糖醛酸（15.4-18.6％）作为组成糖，蛋白质（2.7-3.6％）、水分（4.9-8.3％）和单宁（0.041-0.092％）。作为对作为植物标本收集的树枝进行调查的结果，它们被鉴定为 Anogeissus latifolia Wallich。对其形态特征的详细观察表明，许多晶体细胞在树枝标本的纵剖面上排列。
