Kaemferol was only detected in Verbascum thapsus. Myrcetin was detected in Woodfordia fruticosa, Viburnum cotinifolium, Euphorbia hirta, Vitex negundo and Broussonetia papyrifera. Catechin was detected in Woodfordia fruticosa , Chenopodium ambrosoides and Caryopteris grata. Vitexin was found absent in all the plants under study except Adhatoda vasica, Chenopodium ambrosoides and Peganum harmala. Orientin was detected in Woodfordia fruticosa, Adhatoda vasica, Viburnum cotinifolium, Euphorbia hirta, Vitex negundo, Peganum harmala, Urtica dioica and Caryopteris grata. Rutin and Kaempferol-7-neohesperoside were detected only in Broussonetia papyrifera. Quercitin was detected in Euphorbia hirta, Verbascum thapsus, Caryopteris grata and Mimosa rubicaulis.
