Ledol (1500 ng per band; 2 min at 100°C) is detectable as a dark blue band (Rf = 0.40) via qualitative HPTLC in essential oils from intact R. tomentosum plant material, but is absent in essential oils from R. tomentosum in vitro microshoot cultures[1].
Ledol (1500 ng per band; 30 min dark incubation) does not exhibit DPPH free radical scavenging activity under the tested conditions[1].
Ledol (1500 ng per band; 10 min fluorescent light exposure) does not exhibit superoxide scavenging activity under the tested conditions[1].
Ledol (1500 ng per band; 20 min at 38°C) does not exhibit xanthine oxidase inhibitory activity under the tested conditions[1].
