Fig. 5A,B Arnicae flos (1,4). Arnica montana (1) and Arnica chamissonis (4) show a similar TLC pattern of three orange-yellow flavonoid zones between the blue zones of chlorogenic acid (Rf — 0.45/Tl) and isochlorogenic acids (Rf 0.7-0.95/Tl), The upper zone is due to isoquercitrin and luteolin-7-O-glucoside (T4). The flavonoid glycoside zone in the R, range of hy peroside (3T/T2) is more highly concentrated in sample (4).

Hcterothecae flos (3) has a similar TLC pattern with Arnicae flo.s (4). Together with Calendulae flos (2), it counts as an adulterant of Arnicae flos. The adulterants can be easily detected by the presence of rutin (Rf — 0.4/T1/T2) ( see also Fig. 7). 

Fig. 6A Detection with NP reagent only Arnicae flos (A. montana, A. chamissonis 5-8) Astragalin is found as a bright green fluorescent zone at Rf 0.8 (T5), while the other flavonoid glycoside,s below only appear pale orange-brown (see fig. 5). Blue fluorescent chlorogenic acid at R, 0.45 and caffeic acid at Rp 0.9 are detectable.

B Arnicae flos (A, montana, A. chamissonis 5a-8a). The CHCt, extracts of Arnicae flos ( method see Sect. 7.1.1), developed in system PE, contain sesquiterpene lactones, detectable as violet-grey zones witlt ZM reagent (vis).
