Abstract
The Turkistan Region of southern Kazakhstan lies within the Mountains of Central Asia biodiversity hotspot and harbors a flora of beneficial plants whose traditional use is well documented but whose chemistry and conservation status remain, for most species, formally unassessed. Following the PRISMA extension for Scoping Reviews (PRISMA-ScR), with accepted names verified against Plants of the World Online, this scoping review maps—for the first time as a single co-occurring assemblage rather than isolated single-taxon surveys—the evidence for nine regionally important species across the Nitrariaceae, Fabaceae, Apiaceae and Asteraceae. From 4362 records, 82 were charted by structured per-species extraction. The species span a broad chemical space: β-carboline alkaloids, furanocoumarins, sesquiterpene coumarins, sesquiterpene lactones and flavonoid-rich essential oils, sharing a recurring antioxidant and antimicrobial profile overlaid with species-specific effects such as the anthelmintic santonin of Artemisia cina. For most species the underlying data derive from non-Central Asian populations, limiting regional transferability, and safety evidence is sparse: no acute or repeated-dose toxicity study on regionally collected material was identified, although several species contain monoamine oxidase inhibitors, phototoxic furanocoumarins or thujone-rich oils. We propose a tiered, conservation-aware framework and a prioritized research agenda. Provenance was charted for all 82 records, and the country of origin could be established for 35.
