Introduction. This review deals with the purification of extracts from ballast compounds at the stages of sample preparation in the analysis for steroid saponins and sapogenins. The focus is on solid-phase extraction methods of plant extracts for concentrating steroid saponins and sapogenins and removing ballast compounds from extracts for subsequent accurate chemical analysis. In addition, this review aims to develop the methodological thinking of researchers in selecting a method for solid-phase extraction of steroidal saponins and their genins. Objective: To give a scientometric evaluation of the authors' publication activity on the use of the Phenomenex solid-phase extraction system at the sample preparation stage in the analysis of plant extracts for steroid saponins and sapogenins. Material and methods. A review-analytical study of the Web of Science multidisciplinary abstract-bibliographic database, articles published in 1988-2021, was carried out. Results. Actually, 7 methods of solid-phase extraction of steroidal saponins and steroidal sapogenins were listed in the databases "Web of Science core collection", "KCI-Korean journal database", "Medline", "SciELO citation index"; one of the methods contains information only on the elution reagent at the final stage. A unified concept and scientific rationale for the use of a particular reagent is not evident in the above methods. Conclusion. We have conducted a scientometric analysis of the authors' publication activity on the use of solid-phase extraction of plant extracts in phytochemical studies of steroid saponins and steroid sapogenins in the databases "Web of Science core collection", "KCI-Korean journal database", "Medline", "SciELO citation index" over the entire period of indexing. Only seven articles in various journals have either full or partial description of the technique with the name of the column, type of sorbent, conditions of conditioning, equilibration, washing, introduction of the analyzed solution, and elution of substances.
