Abstract
Hechtia glomerata, a Mexican medicinal plant employed against bacterial infections and as food, is taxonomically related to the genus Tillandsia which has anticancer activity. Organic and aqueous extracts of H. glomerata leaves were prepared and tested for cytotoxic and antibacterial activity. UPLC–QTOF–MS analysis determined the chemical composition of active extracts to find cytotoxic and antibacterial compounds. Hexane extract was cytotoxic against HepG2, Hep3B and MCF7 (IC50: 24–28 µg/mL), whereas CHCl3/MeOH extract against PC3 and MCF7 (IC50: 25 and 32 µg/mL). CHCl3/MeOH extract showed antibacterial activity against Staphylococcus aureus and Enterococcus faecium (MIC: 125 and 62.5 µg/mL). Hexane extract cytotoxic compounds were β-sitosterol, stigmasterol, phytol and ursolic acid. CHCl3/MeOH extract antibacterial and/or cytotoxic compounds were daucosterol, oleanolic acid, resveratrol, quercetin, kaempferol, apigenin, cyanidin, p-coumaric acid and caffeic acid. This plant could be useful against bacterial infections and cancer. However, in vivo studies are needed to determine its toxicity and therapeutic efficacy.
