RESUMEN

ABSTRACT A total of five terpenes was isolated from the bark resin of Schinus molle L., Anacardiaceae, and their structures were determined by spectroscopic techniques. Among these compounds the sesquiterpene hydrocarbon terebinthene showed significant growth inhibitory activity against human colon carcinoma HCT-116 cells. Furthermore, terebinthene and pinicolic acid (5) also showed antibacterial activity against Staphylococcus aureus ATCC 25923 and Bacillus subtilis ATCC 6633.

RESUMEN

ABSTRACT In the presented research we isolated and characterized compounds from Loricaria ferruginea (Ruiz & Pav.) Wedd., Asteraceae. To the best of our knowledge no data on any compounds from L. ferruginea have been published to this day. As main compounds of the hexane extract we found four known coumarins: 5,7-dimethoxycoumarin; 5,7,8-trimethoxycoumarin; 5-hydroxyobliquine and 5-methoxyobliquine. All the structures were determined by spectroscopic and spectrometric methods.

RESUMEN

Abstract A phytochemical investigation of methanol and n-hexane extracts of tuber/roots of Corynaea crassa Hook. f., Balanophoraceae, led to the isolation and characterization of β-sitosterol, lupenone, β-amyrone, lupeol, and β-amyrine. Unusual complex 1:1 mixtures of lupenone/β-amyrone and lupeol/β-amyrine obtained from the extracts were identified by NMR and HR-MS experiments. The structure of the 1:1 lupenone/β-amyrone mixture was confirmed by X-ray analysis. These triterpene ketone derivatives, only distinguished either by 5- or 6-membered E ring, co-crystallize in one common unit cell in the solid state.
