Quality Control Strategies for Differentiation of Kalanchoe Species

Phytochemical Analysis, Volume 36, Issue 8, Page 2385-2400, December 2025.
ABSTRACT Kalanchoe species products are commercially available in local markets and by internationally accessible online retailers and may exhibit quality issues because of misidentification from similar common names and anatomical similarities among related species used as feedstock. This study proposes an approach using UPLC‐MS/MSE and HPTLC, coupled
