ABSTRACT

To determine the effects of 70 % ethanolic extract of Eleutherine bulbosa (Mill.) L. bulbs contained naphtoquinone in blood pressure and lipids profile level of ovariectomized rats. Thin layer chromatography was performed to analyze the content of the Eleutherine bulbosa (Mill.) bulbs extracts using Chloroform : Methanol (7:1) as eluent. This study used white female Sprague-Dawley rats which were divided into 6 groups: SHAM and OVX, both given 0.5 % carboxymethyl cellulose; the positive control group that was given tamoxifen (0.36 mg/200 g B.W.); the three various of doses of extract namely dose 1, 2, and 3 that were given 8, 12, and 18 mg/200 g BW respectively on day 29 until 50. All groups were ovariectomized on day 1, except sham group. Measurement of blood pressure were performed on the day before ovariectomy using non-invasive tool CODA®; and on the second, third, and fourth weeks post-ovariectomy. Three weeks after treatment of hypoestrogen rats by the dose 18 mg/200 g B.W, Eleutherine bulbosa extracts could decrease the systolic blood pressure level to 28.06 %, the diastolic to 30.47 %. Lipid profile of Dose 3 also showed recovery of Triglyceride, LDL and also Total Cholesterol. Eleutherine bulbosa extracts could improve blood pressure of ovariectomized rats by controlling lipids profile level.


Para determinar los efectos del 70 % de extracto etanólico de Eleutherine bulbosa (Mill.) L. en bulbos que contenían naftoquinona, se analizó la presión arterial de ratas ovariectomizadas. Se realizó un estudio de cromatografía de capa fina para analizar el contenido de los extractos de bulbos de Eleutherine bulbosa (Mill.) usando cloroformo:metanol (7:1) como diluyente. En este estudio se utilizaron ratas blancas Sprague-Dawley hembras, que se dividieron en 6 grupos: SHAM y OVX, ambos grupos fueron administrados con carboximetilcelulosa al 0,5 %; grupo control positivo, recibió tamoxifeno (0,36 mg / 200 g de B.W.); y tres grupos restantes, que recibieron tres dosis diferentes de extracto, es decir, dosis 1, 2 y 3 a las que se les administró 8, 12 y 18 mg / 200 g de por peso, respectivamente el día 29 hasta el día 50. Todos los grupos fueron sometidos a ovariectomía en el día 1, excepto el grupo simulado. La medición de la presión arterial se realizó el día anterior a la ovariectomía con la herramienta no invasiva CODA®, y, posteriormente, en la segunda, tercera y cuarta semanas de realizada la ovariectomía. Tres semanas después del tratamiento aplicado a las ratas hipoestrógenas, con la dosis de 18 mg / 200 g por peso, los extractos de Eleutherine bulbosa podrían disminuir el nivel de presión arterial sistólica al 28,06 %, y la diastólica al 30,47 %. La dosis 3 del perfil lipídico mostró mejoría en los niveles de Triglicéridos, LDL y Colesterol Total. Los extractos de Eleutherine bulbosa podrían mejorar la presión sanguínea de ratas ovariectomizadas controlando el nivel del perfil lipídico.

ABSTRACT

Alho do mato (Cipura paludosa, Iridaceae) is a medicinal plant found in the Amazon rain forest, North of Brazil. It has been used to treat algic, inflammatory and infectious processes. The aim of this study was to evaluate the anti-inflammatory and antinociceptive action of the crude Cipura paludosa ethanolic extract at concentrations ranging between 2.0 and 4.0% in Oil and Water cream formulations for topical use. The physical-chemical stability of the formulations was monitored over a six-month period with the use of accelerated stability tests. In order to evaluate the anti-inflammatory and antinociceptive activities, we used a paw edema test induced by carrageenan and a formalin test, respectively. The paw edema test showed that there was a statistical difference in the control group in relation to the treatments. The formalin test did not confirm antinociceptive action of the treatments with the extract in the early phase of the test. However, statistical difference was confirmed for the treatments in relation to the control in the late phase. The antinociceptive and anti-inflammatory activities of Cipura paludosa preparations, as demonstrated in the results, at least partially support the ethno-medical uses of this plant.


Allho do mato (Cipura paludosa, Iridaceae) é uma planta medicinal encontrada na floresta Amazônica, norte do Brasil. Essa planta tem sido usada para tratar dores, processos inflamatórios e infecciosos. O objetivo do estudo foi avaliar a ação anti-inflamatória e antinociceptiva do extrato bruto etanólico de Cipura paludosa, nas concentrações que variaram entre 2,0 e 4,0%, em formulações de cremes óleo e água de uso tópico. A estabilidade físico-química das formulações foi monitorada ao longo de um período de seis meses, com a aplicação de ensaios de estabilidade acelerada. A fim de avaliar as atividades anti-inflamatória e antinociceptiva, utilizou-se um teste de edema de pata induzido por carragenina e um teste de formalina, respectivamente. O teste de edema de pata mostrou que houve uma diferença significativa no grupo controle em relação aos tratamentos. O teste da formalina não confirmou efeito antinociceptivo dos tratamentos com o extrato, na primeira fase do ensaio. No entanto, a diferença estatística foi confirmada para os tratamentos em relação ao controle na segunda fase. As atividades antinociceptiva e anti-inflamatória das preparações com Cipura paludosa confirmam de forma parcial o uso etno-médico desta planta.
