“…The ethanolic extract of the flower buds was also found to have potent anti-inflammatory and antiosteoclastogenic effects (Tran et al, 2019a , 2019b ), antioxidant and antibacterial properties against both Gram-positive and Gram-negative bacteria (Dung et al, 2008 ). A main flavonoid compound, 2′,4′-dihydroxy6′-methoxy-3′,5′-dimethylchalcone (DMC), isolated from the flower buds and seeds, was proven to serve as a chemotherapeutic agent for the prevention or treatment of lung, liver, pancreatic, and cervical cancers (Ye et al, 2004 ; Tuan et al, 2019 ; Utama et al, 2022 ) and inflammatory diseases (Tran et al, 2019a ). Due to the safety and effective pharmacological activity of different solvent preparations from the flower buds of C. operculatus , the present study was conducted to obtain extracts from the flower buds using different solvents (hexane, chloroform, ethyl acetate, butanol, ethanol, methanol, and water) and evaluate the phytochemical content of these extracts (flavonoids, phenolics, tannins, triterpenoid saponins, and alkaloids), their antioxidant capacity, growth inhibitory activity against Helicobacter pylori and Salmonella typhimurium , and enzyme inhibitory effect on H. pylori -urease and α-glucosidase.…”
