“…The EO from leaves of P. lhotzkyanum showed a chemical complexity 64 compounds , as expected for Piperaceae 10,11,15,27 . Its composition in the altitude region 1,145 m revealed a high sesquiterpenes β-elemene 21 and α-zingiberene 13 content and, for the first time, a chemical composition with these major components was found for this plant.…”

“…The presence of caryophyllene oxide in all samples, a stable by-product that results from the oxidation of the caryophyllene sesquiterpene, can often be found in stored EO 54,55 . However, this oxygenated sesquiterpene is usually found in Piper EO 11,26 . Literature records showed that linalool and limonene oxidize when exposed to air.…”

“…This difference in EO composition may be attributed to environmental such as more exposure to sunlight and genetic factors 9,10,44,45 . We also believe that an assessment of the impact of seasonality and circadian rhythm on EO of these species is necessary 11 .…”

IntroductionPiper lhotzkyanum Kunth is known by the popular name beque-cheiroso and belongs to the family Piperaceae 1, 2 . It is a Brazilian medicinal plant that is greatly distributed in the Central and South Americas, mainly in the Brazilian Atlantic Forest. There are no reports of cultivation for this species; however, its popular use is associated with its collection in wild sites to produce popular preparations and for commercialization in traditional fair markets. P. lhotzkyanum is commonly used in Brazilian folk medicine for the treatment of stomach and gastrointestinal disorders, hyposuria, pain relief, and mainly for respiratory problems such as bronchial conditions 3,4 .Phytochemical studies on P. lhotzkyanum collected in high altitude sites 1150 -1200 m high led to the isolation

“…The collected leaves were manually crushed and subjected to hydrodistillation for two hours in a modi ed Clevenger-type apparatus. The EOs were dried over anhydrous sodium sulphate (Na 2 SO 4 , Sigma-Aldrich, Brasil) and the total EO yield was expressed as the percentage value related to fresh plant material (g/ 100 g) (Oliveira et al 2013;Ramos and Moreira 2019;Ramos et al 2020).…”

Piper gaudichaudianum Kunth (Piperaceae) is widely used in Brazil as medicinal and ritualistic. In this study, chemophenetic patterns were evaluated based on leaves’ essential oils (EOs) chemical composition. Several collections were performed to accomplish circadian rhythm and seasonal studies. Besides, a predictive methodology was developed and submitted to Proof of Concept (PoC) to determine the metabolism pattern and evaluate the reduction-oxidation of complex mixtures: Weighted Average Redox Standard (SRO) and General Mixture Redox Index (GMOR). Fresh leaves EOs obtained by hydrodistillation were analyzed by GC-MS and GC-FID. The main identified compounds were sesquiterpenes. Nineteen terpene skeletons were registered. There was chemical composition variation at different phenological stages. EOs varied more between day and night than seasonally. Nine chemotypes are proposed based on our results and those from literature. SRO and GMRO analyzes highlighted a possible redox balance throughout day and night. Compounds per carbon skeleton diversification in EOs are matched by an increase in compounds SRO. We also report for the first time high chemical phenotype plasticity based on EOs analysis and its implications for P. gaudichaudianum chemophenetics, chemosystematics and ecology.
