Seven compounds including abietatriene (1), oleanolic acid (2), quercetagetin 3,7-dimethyl ether (3), luteolin (4), p-hydroxybenzoic acid (5), p-methylbenzoic acid (6), and protocatechuic acid (7) were isolated from the n-hexane: ethyl acetate (1:1) extract of Vitex negundo leaves collected in Binh Thuan Province. Their chemical structures were elucidated by comparing their spectroscopic data with reported data in the literature. Six compounds (exception of 4) were known to be present in Vitex negundo.

In present study Vitex negundo leave’s extract was used to assess the antibacterial activity on cotton fabric. Extraction of phytochemicals was carried out using different solvents like ethanol and aqueous. Total phenolic content (TPC) results revealed that TPC of Vitex negundo leave’s extract were highest in case of ethanolic extraction as compared to aqueous. It was observed that mild to moderate antibacterial properties were present in ethanolic extract as compared to aqueous extract. Clear zone of inhibition was observed on cotton fabric against E coli and S. aureus.

In vitro studies, aqueous extract of leaves of plants namely Karu (Roylea elegans), Artemisia (Artemisia roxburghiana), Neem (Azadirachta indica), Bana (Vitex negundo), Tulsi (Ocimum sanctum) and seed of Darek (Melia azedarach) were found effective in inhibiting the growth of the B. dothidea causing white rot in apple. These botanicals were mixed together and formulations were made in water (Botanical Formulations 1) and Cow urine (Botanical Formulations 2) on weight and volume basis.
