The intermediate/interday/intra-day precisions were below 2 % (n=3). Recovery was in the range of 94.6 and 99.1 %.

Braz. J. Pharmacog. 28, 631-639 (2018). HPTLC of 3-O-α-L-rhamnopyranosyl-(1→ 2)-α-L-arabinopyranosyl pomolic acid, 2,4,6-trihydroxy-4-methoxybenzophenone-2-O-β-d-glucoside, hyperoside, geniposidic acid, nicotiflorin, narcissin, randiasaponin IV and rutin in the leaves, stems and roots of Fadogia agrestis on silica gel with chloroform – ethyl acetate – methanol – formic acid 15:30:10:4. Detection by immersion in the anisaldehyde–sulfuric acid reagent, followed by heating at 100 ºC for 3 min. The HPTLC fingerprinting method was suitable for rapid decisive authentication and comparison of differences among samples of identical source.
