Vent. stem bark and leaves, collected in Vietnam. The oils were predominant by oxygenated sesquiterpenes. Major compounds in the stem bark oil included (Z)-dihydro-apofarnesol (13.84%), ishwarane (8.96%), spathulenol (7.87%), palmitic acid (7.58%), and (E)-dihydro-apofarnesol (6.71%), while the leaf oil was characterized by spathulenol (34.78%), n-hexanol (16.64%), ishwarane (7.33%), and (Z)-dihydro-apofarnesol (6.41%). B. papyrifera essential oils showed moderate cytotoxicity against MCF-7 and HepG2 cancer cell lines, with IC50 values of 33.2-56.3 µg/mL. The oils strongly scavenged DPPH radicals with IC50 values of 33.15-47.83 µg/mL, as well as remarkably inhibited nitric oxide (NO) and prostaglandin E2 (PGE2) production with IC50 values of 24.15-88.70 µg/mL. In silico ADME and toxicity predictions indicated favorable drug-likeness, good gastrointestinal absorption, and low toxicological risk for the major compounds. Molecular docking revealed stable binding of the major compounds to protein targets cyclooxygenase-1 (COX-1), COX-2, 5-lipoxygenase (5-LOX), and xanthine oxidase (XO), with binding energies ranging from -4.3 to -8.0 kcal/mol. Collectively, B. papyrifera essential oils are promising sources of bioactive compounds with antioxidant and anti-inflammatory potential.PMID:42773741 | PMC:PMC13598410 | DOI:10.1002/cbdv.71730
