Abstract
The flowers of Quararibea funebris are used to make a traditional drink called tejate, to which they add aroma, flavor and consistency. The study aims to profile the morphoanatomy of the floral parts of Q. funebris and analyze the changes in its volatile chemical composition during the drying process from 0 to 180 days by HS-SPME-GC-MS. The calyx, corolla, androecium, and gynoecium have distinct characteristics, such as non-glandular fused stellate trichomes, calcium oxalate crystals, and large secretory ducts. Histochemical localization reveals the presence of mucilage and total lipids in all parts of the flower. The chemical analysis of the essential oil, extracted from the flowers, showed that transfarnesol and geraniol were the most abundant compounds, with a yield of 0.04 %. HS-SPME analysis indicated that fresh flowers had a more complex composition than dried ones. In total, 31 components were identified. Nonanal and geranyl acetone were found to be distinctive components of dried flowers. Microscopic examination helps in identifying and authenticating raw materials and also reveals the presence of secretory ducts in all floral parts, which is a distinctive feature. The chemical profile of volatiles provides an important parameter for the evaluation of the quality of Rosita de Cacao raw materials.

Abstract
Abstract
α-Sanshool is an alkamide isolated from the stem bark of Zanthoxylum liebmannianum, a Mexican medicinal plant known as Colopahtle. Our research group has reported that the intraperitoneal administration of α-sanshool induces tonic-clonic seizures in mice. In the present study, we investigated the convulsive effect of this alkamide and elucidated its mechanism of action by comparing with well-known convulsive and anticonvulsive drugs in an in vivo approach. α-Sanshool showed a potent (ED50 [CL 95%]=3.06 [2.92–3.22] mg/kg) and immediate (2±2 s) seizure effect after the intraperitoneal administration in mice. The convulsive effect of this alkamide was only observed for intraperitoneal administration; the oral route did not show any effect. α-Sanshool was less potent than strychnine (ED50 [CL 95%]=1.53 [1.44–1.62] mg/kg), but more effective than bicuculline, 4-aminopyridine, affinin, and pentylenetetrazol, in that order. The seizures induced by α-sanshool were reduced by capsazepine and diazoxide, suggesting the involvement of TRPV1 and potassium channels in the mechanism of action of this compound.
