Abstract
El principal objetivo del presente estudio fue demostrar el efecto analgésico del
extracto hidroalcohólico de las hojas de Senna multiglandulosa (Jacq.) H.S. Irwin &
Barneby (Miyhua tanquis) en ratones inducidos a dolor agudo. El dolor fue inducido
con ácido acético al 1% vía intraperitoneal a dosis de 0.1 Ml/10g. Se usaron 42
ratones distribuidos al azar en 7 grupos, G1: blanco: solución salina fisiológica (SSF)
(5 mL/kg) vía oral (v.o); G2: control positivo: ácido acético (AcOH) 1%, G3: control
farmacológico (CF) 1: tramadol 40 mg/Kg + AcOH 1%, G4: CF2 paracetamol 300
mg/kg + AcOH1%, G5: grupo experimental (GE) 1: extracto Senna 50 mg/kg + AcOH
1%, G6: GE 2: extracto Senna 100 mg/kg + AcOH 1%, G7: GE 3: extracto Senna
200 mg/kg + AcOH 1%. En la prueba de solubilidad se observó que el extracto fue
muy soluble en agua y metanol, soluble en etanol, poco soluble en cloroformo e
insoluble en acetona, hexano y éter de petróleo. En el tamizaje fitoquímico se
encontró metabolitos secundarios como son: compuestos fenólicos, flavonoides,
alcaloides, esteroides y/o triterpenoides. Todos los grupos experimentales (GE)
presentaron un efecto analgésico significativo cuando fueron comparados con el
grupo control farmacológico (CF1, CF2). El efecto analgésico fue a dosis
dependiente, la dosis que presentó mayor efecto analgésico fue 200 mg/kg. (60%),
luego (GE 2)100mg/kg (36%) y (GE 1) 50mg/kg (24%). El efecto del grupo
experimental (GE3) (200 mg/kg) fue superior al paracetamol 300mg/kg (CF2) (50%)
e inferior al tramadol 40mg/kg (CF1) (84%). Sin embargo, no fue encontrado
diferencia significativa cuando fueron comparados el (CF2) y (GE 3) p<0.05.
Conclusión, el extracto hidroalcohólico de las hojas de Senna multiglandulosa
(Jacq.) H.S. Irwin & Barneby (miyhua tanquis) tiene efecto analgésico en ratones
inducidos a dolor agudo.
The main objective of the present study was to demonstrate the analgesic effect of the hydroalcoholic extract of the leaves of Senna multiglandulosa (Jacq.) H.S. Irwin & Barneby (Miyhua tanquis) in mice induced acute pain. The pain was induced with 1% acetic acid intraperitoneally at a dose of 0.1 Ml / 10g. 42 randomized mice were used in 7 groups, G1: white: : physiological saline (SSF) (5 mL / kg) orally (v.o); G2: positive control: acetic acid (AcOH) 1%, G3: pharmacological control (CF) 1: tramadol 40 mg / Kg + AcOH 1%, G4: CF2 paracetamol 300 mg / kg + AcOH1%, G5: experimental group (GE ) 1: Senna extract 50 mg / kg + 1% AcOH, G6: GE 2: Senna extract 100 mg / kg + 1% AcOH, G7: GE 3: Senna extract 200 mg / kg + 1% AcOH. In the solubility test it was observed that the extract was very soluble in water and methanol, soluble in ethanol, poorly soluble in chloroform and insoluble in acetone, hexane and petroleum ether. Secondary metabolites were found in the phytochemical screening such as: phenolic compounds, flavonoids, alkaloids, steroids and / or triterpenoids. All experimental groups (GE) had a significant analgesic effect when compared to the pharmacological control group (CF1, CF2). The analgesic effect was dose dependent, the dose that presented the greatest analgesic effect was 200 mg / kg. (60%), then (GE 2) 100mg / kg (36%) and (GE 1) 50mg / kg (24%) The effect of the experimental group (GE3) (200 mg / kg) was superior to paracetamol 300mg / kg (CF2) (50%) and inferior to tramadol 40mg / kg (CF1) (84%). However, no significant difference was found when (CF2) and (GE 3) p <0.05 were compared. Conclusion, the hydroalcoholic extract of the leaves of Senna multiglandulosa (Jacq.) H.S. Irwin & Barneby (miyhua tanquis) has an analgesic effect in mice induced to acute pain.
