A simple HPLC method was applied for idenfication of flavonoid aglycones in plant stains. Flavonoids were detected from as low as 1 mg of dried leaves and fresh leaves stains on 2.1 cm[2] of cotton and 3.2 cm[2] nylon fabrics. Plant species were identified by comparing the chromatogram of stain with that of plant extract. This method offers a great help in identifying plant stains in cases of criminal investigation

Cromatografia Líquida de Alta Pressão/instrumentaçãoRESUMO
From chrysanthemum vulgare [L.] Bernh. Three sequiterpene lactones were isolated and identified as 3 beta-hydroxycostunolide [I], 2 alpha, 8 beta-dihydroxycostunolide [II] and tatridin B [III]. In addition, three flavonoids viz. apigenin, luteolin and apigenin-7-0-glucoside were isolated. The structures of these compounds were depicted through spectral studies. All the isolated compounds were reported for the first time from the titled plant
