How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

Abutilon theophrasti Medic. is a widely distributed species belonging to the Malvaceae family. It represents a potential source of bioactive compounds with antioxidant, anti-inflammatory, and antimicrobial properties. Despite the species’ pharmacological significance and its widespread distribution, information on the diagnostic pharmacognostic characteristics of A. theophrasti Medic. remains limited, and no such studies have previously been conducted on raw materials growing in Kazakhstan. The objective of this study was to ascertain the diagnostically significant morphological, anatomical, and histochemical characteristics of A. theophrasti Medic. in order to facilitate the identification and pharmacognostic standardization of medicinal plant raw materials. The subjects of the study were the plant’s aerial and underground organs, including leaves, stems, petioles, inflorescences, flowers, fruits, and roots. A comprehensive analysis of the raw material was conducted using a variety of analytical methods, including macroscopic, microscopic, and histochemical approaches. The study’s findings enabled the identification of characteristic features of the plant’s aerial and underground organs through macroscopic analysis. Microscopic examination revealed diagnostically significant characteristics of the species A. theophrasti Medic., including an anomocytic stomatal apparatus, numerous simple and stellate trichomes, calcium oxalate druses, and characteristic anatomical features of the leaf, stem, sepals, and root. Taken together, these characteristics form a diagnostic complex that can be used to identify this species. Histochemical analysis revealed the localization of phenolic compounds, flavonoids, and trace amounts of essential oil in the tissues of the leaf petiole and root. However, alkaloids, starch, and sesquiterpene lactones were not detected. The identified morphological, anatomical, and histochemical data serve to supplement the information on the diagnostically significant characteristics of the species, carrying practical importance for the quality assessment of plant raw materials.
