Introduction. Aloe leaves are widely used to prepare drugs. To preserve the biologically active substances and pharmacological properties of its medicinal plant materials, conservation methods, such as drying and freezing, are used. Objective: to comparatively analyze the identity and good quality of fresh, frozen, and dried arborescent aloe (Aloe arborescens) leaves. Material and methods. The object of the investigation was fresh, dried, and frozen arborescent aloe leaves harvested in 2018. It used the procedures described in the 14th edition of the State Pharmacopoeia of the Russian Federation. Results. The characteristics of arborescent aloe leaves authors were supplemented with the identity of fresh, frozen, and dried leaves. The main quality indicators were estimated for raw materials. To establish the good quality of aloe leaves, indicators, such as the content of extractive substances and the dry residue in juice, were proposed. Conclusion. The findings can be used to draft the pharmacopoeial article «Arborescent aloe (Aloe arborescens) leaves» for the State Pharmacopoeia of the Russian Federation. Freezing was shown to be the best way to preserve aloe leaves.
