Abstract

Hyptis suaveolens (L.) Poit. is a medicinal plant with promising potential; however, its cytotoxic activity has not been investigated in Vietnam, particularly in Hue City. This study aimed to analyze the morphological and anatomical characteristics, chemical composition, and cytotoxic activity of essential oil extracted from the aerial parts of H. suaveolens collected in Huong Long Ward, Phu Xuan District, Hue City. Morphological and anatomical features were examined using double-staining techniques and light microscopy; essential oil was extracted by steam distillation, its chemical constituents were identified using gas chromatography–mass spectrometry (GC-MS), and cytotoxicity was evaluated on HepG2, A549, and MCF7 cancer cell lines. The botanical characteristics of H. suaveolens from Hue were consistent with those reported in other regions. A total of 33 compounds accounting for 80,26% of the essential oil were identified, with sesquiterpenes (30,98%) and monoterpenes (30,91%) being predominant. The major components were (E)-caryophyllene (18,34%) and 1,8-cineole (18,08%). The essential oil exhibited cytotoxic activity against cancer cell lines with IC₅₀ values of 10,94, 11,77, and 9,50 µg/mL, respectively. This study provides the first report on the botanical features, chemical composition, and cytotoxic potential of H. suaveolens essential oil in Vietnam.
