HPTLC and reverse phase HPLC methods for the simultaneous quantification and in vitro screening of antioxidant potential of isolated sesquiterpenoids from the rhizomes of Cyperus rotundus.

Three sesquiterpenoids solavetivone, aristolone and nootkatone were isolated from the acetone extract of Cyperus rotundus by silica gel column chromatography and identified by spectral studies. Solavetivone has been isolated for the first time from the species. Simple, sensitive and selective HPTLC and HPLC methods with ultraviolet detection (245 nm) were… CONTINUE READING
