ABSTRACT

ABSTRACT An overview is provided on the cytogenetic of Chilean plants, highlighting information gathered from more than a century of work carried out by foreign and national researchers who have contributed to the study of native species. We briefly present the progress made to date and also emphasize some strategies that, in our opinion, could spur further advances in this second century of cytogenetic studies in Chilean plants.


RESUMEN Se presenta una visión general de la citogenética de plantas chilenas, destacando información recopilada durante más de un siglo de trabajo realizado por investigadores nacionales y extranjeros que han contribuido al estudio de las especies nativas. Presentamos brevemente los progresos realizados hasta la fecha y también destacamos algunas estrategias que, en nuestra opinión, podrían impulsar mayores avances en este segundo siglo de estudios citogenéticos en plantas chilenas.

ABSTRACT

Chilean Plants Cytogenetic Database (CPCD) is a resource available on line in electronic format, which provides a cytogenetics catalogue for continental and insular Chilean vascular plants. In this report, we made reference to the CPCD, discussing aspects on its coverage, features and usages. Currently, the database stores cytogenetic information for 247 species, 107 genera, and 55 families belonging to Pteridophyta, Pinophyta, and Magnoliophyta.

ABSTRACT

ABSTRACT High-resolution mass spectrometry is currently used to determine the mass of biologically active compounds in plants and UHPLC-Orbitrap is a relatively new technology that allows fast fingerprinting and metabolomics analysis. In this work, several phenolic compounds including eleven phenolic acids, two fatty acids, two chromones and fourteen flavones were rapidly identified in the methanolic extracts of aerial parts and flowers of the unique Chilean species Ophryosporus triangularis Meyen, Asteraceae, growing in the Atacama Desert by means of ultrahigh resolution liquid chromatography orbitrap MS analysis (UHPLC-PDA-OT-MS) for the first time. The UHPLC-MS fingerprint generated can be used for the authentication of this endemic species. The methanolic extracts of the aerial parts and flowers showed also antioxidant capacities (65.34 ± 1.32 and 52.41 ± 1.87 µg/ml in the DPPH assay, 184.88 ± 13.22 and 196.80 ± 13.28 µmol TE/g dry weight in the ferric reducing power assay and 56.17 ± 3.03 and 65.41 ± 1.96% in the superoxide anion scavenging assay, respectively).
