Blank, Arie Fitzgerald; Costa, Andressa Giovannini; Arrigoni-Blank, Maria de Fátima; Cavalcanti, Sócrates Cabral de Holanda; Alves, Péricles BarretoJava citronella (Cymbopogon winterianus Jowitt) is member of the Poaceae family. Java citronella volatile oil has been reported to be among the volatile oils, showing repellent, antimycotic, and acaricide activities. It has been known that agronomical factors have a great effect on both the quality and quantity of essential metabolites. For this reason, it is necessary to determine optimum levels of agronomical...
Influence of the harvesting time, temperature and drying period on basil (Ocimu...
Carvalho Filho, José Luiz Sandes de; Blank, Arie Fitzgerald; Alves, Péricles Barreto; Ehlert, Polyana Aparecida DiasOcimum basilicum L. essential oil with high concentration of linalool is valuable in international business. O. basilicum essential oil is widely used as seasoning and in cosmetic industry. To assure proper essential oil yield and quality, it is crucial to determine which environmental and processing factors are affecting its composition. The goal of our work is to evaluate the effects of harvesting time, tempe...

Arrigoni-Blank, Maria de Fátima; Oliveira, Ricardo Luiz Barros; Mendes, Sandra Santos; Silva, Paulo de Albuquerque; Antoniolli, Ângelo RobertoBackground Peperomia pellucida is popularly known as coraçãozinho in the Brazilian northeast and is used in the treatment of abscesses, furuncles, and conjunctivitis. Our work aimed to determine the term of the development stages and the species cycle in the four seasons of the year (complete development, beginning of bloom, complete bloom, and seed set), verifying the plant's therapeutic profile during the fou...
Antinociceptive activity of the aqueous extract of Bauhinia cheilantha (Bong.) ...
Antoniolli, Ângelo Roberto; Silva, Adriana M. O.; Teixeira-Silva, Flávia; Nunes, Rogéria de Souza; Marçal, Rosilene MorettiBauhinia cheilantha (Leguminosae-Caesalpinioideae) é uma planta comum da caatinga amplamente utilizada na medicina popular como analgésica. Para verificar farmacologicamente este efeito, a atividade antinociceptiva desta planta foi verificada através do extrato aquoso da entre-casca, administrado em camundongos. O extrato (400 mg/kg), administrado por via oral 60 minutos antes do teste reduziu a nocicepção em 5...
Carvacrol, (−)-borneol and citral reduce convulsant activity in rodents
Quintans-Júnior, Lucindo José; Guimarães, Adriana Gibara; Araújo, Bruno Eduardo Silva de; Cavalcanti, Sócrates Cabral de HolandaCarvacrol, a monoterpenic phenol present in essential oils of the Labiatae family, has been used through the ages as a source of flavor in food and for medicinal purposes. Borneol is a monoterpene found in several species of Artemisia and Dipterocarpaceae, used for anxiety, pain and anesthesia in traditional Chinese. Citral, a mixture of two geometrical isomers (neral and geranial), is one of the most important...

Lima, Gabrielle Mendes; Quintans-Júnior, Lucindo José; Thomazzi, Sara Maria; Almeida, Emyle Mayra Santana Alves; Melo, Mônica Santos deChrysopogon zizanioides (L.) Roberty, Poaceae, is a plant widely used in northeast Brazil in folk medicine for the treatment of various pathological conditions, including inflammatory pain. The present study evaluated the antinociceptive and anti-inflammatory effects of C. zizanioides essential oil (EO) in rodents. EO was further characterized by GC/MS. The major components of EO were identified as khusimol (19...
p-Cymene reduces orofacial nociceptive response in mice
Santana, Michele Fraga de; Quintans-Júnior, Lucindo José; Cavalcanti, Sócrates Cabral de Holanda; Oliveira, Makson Gleydson Brito deThis study investigated the possible antinociceptive effect of p-cymene in different tests of orofacial nociception. The animals (mice) were pretreated (i.p.) with p-cymene (25, 50, 100 mg/kg), morphine (5 mg/kg), or vehicle (0.2% Tween 80+saline), and were then subsequently administered, subcutaneously into their upper lip: formalin, capsaicin, and glutamate. The nociceptive behavior response was characterized...
Evaluation of the lethality of Porophyllum ruderale essential oil against Biomp...
Fontes Júnior, Ulzias Rodrigues; Ramos, Cledison Santos; Serafini, Mairim Russo; Cavalcanti, Sócrates Cabral de Holanda; Alves, Péricles BarretoThe essential oil of flowers and leaves of Porophylum ruderale (Asteraceae) was investigated for its molluscicidal and larvicidal activities, and its toxicities to brine shrimps. The essential oil was analyzed by gas chromatography-mass spectrometry (GC/MS). GC/MS analysis showed a total volatile content of 99.98% in the P. ruderale oil (PREO). The major components in PREO were identified as (E)-β-ocimeno (93.9...
