essential oil composition of the fruits of periploca laevigata aiton subsp angustifolia labill markgraf apocynaceae periplocoideae
Natural Product Research, 2011Co-Authors: Pietro Zito, Maurizio Sajeva, Maurizio Bruno, Antonella Maggio, Sergio Rosselli, Felice Senatore, Carmen FormisanoAbstract:The essential oil of the fruits of Periploca laevigata Aiton subsp. angustifolia (Labill.) Markgraf (Apocynaceae) from Lampedusa Island was obtained by hydrodistillation and its composition was analysed. The analyses allowed the identification and quantification of 64 volatile compounds belonging to different classes. The most abundant compounds were nonacosane, heptacosane, hentriacontane and δ-cadinene. Among the volatile compounds identified in the fruits of P. laevigata subsp. angustifolia, 31 are present in other taxa of Apocynaceae, 19 have antimicrobial activity and four are pheromones for the butterfly Danaus chrysippus. The possible ecological role of the volatile compounds found is briefly discussed.

Efecto hepatoprotector del extracto hidroalcohólico de las hojas de nasturtium officinale w.t. aiton (berro) en ratas albinas inducidas con paracetamol a hepatotoxicidad aguda
Universidad Inca Garcilaso de la Vega, 2019Co-Authors: Manrique Izaguirre, Kelly Estefania, Saez Herrera, Karina GloriaAbstract:Diversas plantas como las frutas y hortalizas contienen en su composición fitonutrientes y nutraceúticos importantes para la salud, para prevención y tratamiento de enfermedades, como es el caso del berro. El objetivo central del presente estudio de investigación fue determinar el efecto hepatoprotector del extracto hidroalcohólico de las hojas de Nasturtium officinale W.T. Aiton (berro) en ratas albinas inducidas con paracetamol a hepatotoxicidad aguda. El estudio fue de tipo experimental, se realizó la marcha fitoquímica al extracto y para el experimento hepatoprotector se empleó 36 ratas albinas divididos en 6 grupos (G) a los cuales se administró por vía oral; G1: Solución salina fisiológica (SSF) 5 mg/kg; G2: SSF 5 mg/kg + Paracetamol 400 mg/kg, G3: Berro 200 mg/kg + Paracetamol; G4: Berro 300 mg/kg + Paracetamol; G5: Berro 500 mg/kg + Paracetamol y G6: Silimarina 100 mg/kg + Paracetamol. El paracetamol fue el agente inductor de toxicidad hepática aguda en la marcha fitoquímica se halló la presencia de alcaloides, flavonoides, compuestos fenólicos, saponinas, antraquinonas, esteroides y/o triterpenoides, el extracto presentó solubilidad en solventes polares como el agua y el etanol. La dosis del extracto de 500 mg/kg fue que presentó mejor efecto hepatoprotector que las otras dosis ensayadas, es decir el efecto fue dosis dependiente y significante (p0.05), el efecto se evidenció por disminución de los niveles de TGO, fosfatasa alcalina, bilirrubina total, proteínas totales y aumento de albúmina. Se concluyó que el extracto hidroalcohólico de las hojas de Nasturtium officinale W.T. Aiton (berro) mostró tener efecto hepatoprotector en ratas albinas inducidas con paracetamol a hepatotoxicidad aguda.Various plants such as fruits and vegetables contain in their composition phytonutrients and nutraceuticals important for health, for prevention and treatment of diseases, such as watercress. The main objective of this research study was to determine the hepatoprotective effect of the hydroalcoholic extract of the leaves of Nasturtium officinale W.T. Aiton (watercress) in albino rats induced with paracetamol to acute hepatotoxicity. The study was of an experimental type, the phytochemical march study was carried out on the extract and for the hepatoprotective experiment, 36 albino rats divided into 6 groups (G) were used, which were administered orally; G1: Physiological saline solution (SSF) 5 mg / kg; G2: SSF 5 mg / kg + Paracetamol 400 mg / kg, G3: Watercress 200 mg / kg + Paracetamol; G4: Watercress 300 mg / kg + Paracetamol; G5: Watercress 500 mg / kg + Paracetamol and G6: Silymarin 100 mg / kg + Paracetamol. Paracetamol was the agent that induces acute liver toxicity. Results; in the phytochemical march the presence of alkaloids, flavonoids, phenolic compounds, saponins, anthraquinones, steroids and / or triterpenoids was found, the extract showed solubility in polar solvents such as water and ethanol. The dose of the 500 mg / kg extract showed a better hepatoprotective effect than the other doses tested, that is, the effect was dose-dependent and significant (p 0.05), the effect was evidenced by a decrease in the levels of TGO, TGO, alkaline phosphatase, total bilirubin, total proteins and albumin increase. Conclusion, the hydroalcoholic extract of the leaves of Nasturtium officinale W.T. Aiton (watercress) showed to have hepatoprotective effect in albino rats induced with paracetamol to acute hepatotoxicity
