Piper peltatum L. is used for the treatment of inflammation, malaria, and other ailments. 4-Nerolidylcatechol (4-NC) is a valuable natural product that has important anti-inflammatory, antima-larial, and antioxidant properties. 4-NC is a component of P. peltatumand P. umbellatum extracts, which are used in cosmetics.The aim of this work was to evaluate the production of plant biomass and the production of 4-NC in roots of cultivated P. peltatumover a full life cycle. Seedlings were produced in a greenhouse and then transplanted. The weight of dry plant parts (leaves, stems, roots, and inflorescences); numbers of stems, leaves, and inflorescences; and the leaf-to-stem ratio were evaluated at intervals of 60 days after transplanting (DAT). Extracts were prepared using 1:1 ethanol-chloroform and an ultra sound bath. Roots, leaves, and inflorescences contained 4-NC according toTLC photo densitometry analysis. Quantification of 4-NC in root extracts was performed using HPLC?DAD analysis. Per-hectare production of 4-NC by roots was estimated based on quantitativ e HPLC analysis and biomass data. Optimal per-hectare yields of 4-NC were obtained by harvesting roots between 350 and 400 DAT. In this period, the average yield was 27 kg 4-NC per hectare. Importantly, at the time of maximal overall production of root biomass (470 DAT), there was a decrease in the production of 4-NC(23.8 kg/ha), probably due to the on set of senescence. |
