Analgesic activity
Following the folk claim, the analgesic activity of the methanol extract of CV was evaluated in mice using the
Rha-O
Dihydrokaempferol-4'-xyloside
OH O
OH
acetic acid-induced writhing and the tail flick, tail clip, and tail immersion methods. The results of the study showed significant activity of the extract at the higher concentration of 400 mg/mL as compared to diclofenac sodium, included as a reference standard (Parimaladevi et al., 2003).
In another study, the aqueous extract of the seeds of CV
OCH3 O
3'4'-Dihydroxy-5-methoxy flavanone-7-O-α-L-rhamnopyranoside
was evaluated for its analgesic activity in mice and found to possess significant activity (Singh & West, 1991).
