Extracts of the whole herb of Rorippa indica contain benzoic acid, ferulic acid, vanillic acid, gallic acid, glucosyl sinapinate, β‐sitosteroyl‐3‐ O ‐β‐glucoside, quercetin‐7‐ O ‐rhamnoside, kaempferol, kaempferol‐3‐ O ‐β‐glucoside, −7‐ O ‐β‐glucoside, −7‐ O ‐rhamnoside, −3‐ O ‐arabinoside, and −3‐ O ‐glucosyl‐7‐ O ‐rhamnoside together with a new compound, roripanoside. The new compound was elucidated as kampferol‐7‐ O ‐(6″′‐ O ‐caffeoyl)glucosyl (1 → 4) rhamnoside on the basis of spectral and chemical evidence.
