J. AOAC Int. 102, 714-719 (2019). HPTLC fingerprint of the aerial parts of Isodon lophanthoides (Buch. Ham. ex D. Don) Hara (IL) on silica gel with toluene - chloroform - ethyl acetate - formic acid 30:10:10:1. Detection by spraying with 10 % sulfuric acid in ethanol, followed by heating at 105 ºC. Among the 12 bands with good resolution, four ursane-type triterpenoids were recognized as ursolic acid (hRF 61), 2α-hydroxy-12-en-28-ursolic acid (hRF 25), 2α,19α-dihydroxy-12-en-28-ursolic acid (hRF 19), and 2α-O-β-D-glucoside-12-en-28-ursolic acid (hRF 3). The method allowed to distinguish Isodon lophanthoides from its substitute, I. lophanthoides var. gerardianus and was a prospect for the quality control of I. lophanthoidis herba.
