The Piperaceae family comprises 14 genera and approximately 700 species, which are distributed in the tropical and subtropical zones of the world. In Guatemala, approximately 88 species of Piper distributed in different regions of the country are described, of which very little chemical and pharmacological information is found.
The present study contributes to the chemical study of the most important aromatic species of the genus Piper in Guatemala. 16 species were identified in 3 departments of Guatemala; In Suchitepéquez, 4 species were found (Piper umbellatum, P. oradendrnm, P. patulum and P. jaequemontianum); in Alta Verapaz, 8 species were found (P. geniculatum,R jaequemontianum, P. obliquom, P. variabile, P. phytolaccifoiium, P. shippianum, P. sempervirens and P hispidum) and in Izabal 4 species (P. peltatum, P donnell smithii, P. fallens, and R. diandrum).
The essential oil of each species was obtained by hydrodistillation and its yield was calculated. The chemical characterization of the extracts was carried out by means of macro and semi-micro assays and thin layer chromatography, determining the presence of
alkaloids, flavonoids, anthraquinones, saponins, bitter principles, volatile oils and dressings. The constituents of the essential oils were identified by GC-EM, it was observed that R phytolaccifoiium was the species that presented the highest number of constituents (42), among which the majority were identified: Germacrane D 18%: P.umbellatum (39), presented as majority E'-nerolidol 23.4% and P. variabile (36), which presented as majority camphor 28.4%, and P. jaequemontianum that presented linalool 69.4% as majority. an interesting constituent in the perfumery industry.
