The antiproliferative constituents in the MeOH extracts of the aerial parts of Lippia dulcis Trev. and Lippia canescens Kunth (Verbenaceae) were investigated. Activity-guided chemical investigation of the MeOH extracts resulted in the isolation of the three bisabolane-type sesquiterpenes [(+)-hernandulcin (1), (-)-epihernandulcin (2), and (+)-anymol (3)] and four phenylethanoid glycosides [acteoside (4), isoacteoside (5), martynoside (6), and a new diacetylmartynoside (7)] from the former, and four phenylethanoid glycosides [acteoside (4), isoacteoside (5), arenarioside (8), and leucosceptoside A (9)] and three flavones [desmethoxycentaureidin (10), eupafolin (11), and 6-hydroxyluteolin (12)] from the latter. Antiproliferative activity of the isolated compounds against murine melanoma (B16F10), human gastric adenocarcinoma (MK-1), and human uterine carcinoma (HeLa) cells was estimated. (+)-Anymol (3), acteoside (4), isoacteoside (5), arenarioside (8), eupafolin (11), and 6-hydroxyluteolin (12) had GI50 values of 10-16 microM against B16F10 cell. Desmethoxycentaureidin (10) and eupafolin (11) showed high inhibitory activity against HeLa cell growth (GI50 9 microM, and 6 microM, respectively).

For the first time, our study provides a comprehensive examination of the anti-cancer effects of structural isomers of carene in breast cancer cells, specifically focusing on cell cycle inhibition and the induction of apoptosis. We utilized the hydro-distillation method to extract Piper nigrum seed essential oil (PNS-EO) and identified its bioactive components through gas chromatography-mass spectrometry (GC-MS) analysis. A total of 46 bioactive compounds were isolated via hydro-distillation, identified through GC-MS analysis, and validated by co-injection using GC analysis.

This study aims to investigate the in vitro antiproliferative and pro-apoptotic/apoptotic potential of active constituents of essential oils on two cancer cell lines; namely, breast adenocarcinoma (MCF-7) and urinary bladder cancer (T24). Essential oils active constituents (EO-ACs) entail a spectrum of phytochemicals with widely demonstrated anticancer potential. We assessed the effects of eight essential oils active constituents on T24 and MCF-7 cell lines in both dose- (16-1024 µg/mL) and time-dependent manners.

Nine new structurally diverse filicinic acid-based meroterpenoids (-) with four kinds of carbon skeletons were isolated from the rhizomes of . Their structures, including the absolute configurations, were elucidated by comprehensive analysis of spectroscopic data, quantum chemical calculations, and single-crystal X-ray diffraction. Structurally, compounds - feature an unprecedented 6/6/5/6/6/6 hexacyclic system with a rare oxaspiro[4.
