Six Iranian and seven Turkish samples of commercial gum tragacanth, and a sample of Turkish 'gum traganton', have been studied. Their nitrogen content varied from 0.17 to 0.58%. Their amino acid compositions are characterized by the presence of very large but variable proportions of hydroxyproline and substantial proportions of serine, proline and valine. The data presented may be useful for extending the current specifications for identity and purity, at present based solely on polysaccharide parameters, for gum tragacanth (E413).
对六个伊朗和七个土耳其的商业刺梧桐树胶样本，以及一个土耳其“gum traganton”样本进行了研究。它们的氮含量在0.17%至0.58%之间变化。它们的氨基酸组成特点是含有比例非常大但各不相同的羟脯氨酸，以及相当比例的丝氨酸、脯氨酸和缬氨酸。所呈现的数据可能有助于扩展目前仅基于多糖参数的刺梧桐树胶（E413）的身份和纯度规范。
