Nootropic activity of methanolic extract from Evolvulus alsinoides Linn. in mice with scopolamine-induced amnesia.

Plants have been used as therapeutic agents in both un-ionized (Unani, Ayurveda) and unstructured forms since ancient times. Therefore, it is of interest to document the nootropic activity of methanolic extract from Evolvulus alsinoides Linn (Vishnukranthi) in mice with scopolamine-induced amnesia. Healthy male Swiss albino mice ranging between 25 and 30 g were used in the study. Scopolamine induced amnesia, the following two tests are performed, elevated plus maze test, passive avoidance test. The mean time spent in the open arm, closed arm, and central platform for each group of animals. The total transitions were 12.6±0.89 by GS group mice, 3.4±0.55 by GSP group mice, 7±0.71 by GSLD group mice and 10±0.71 by GSHD group mice. A significant difference was seen between GS and GSP group mice means. The mean time in the safe zone and shock zone for each group of animals when comparing to Group 2 Vs Group 3, 4 showed a statistical significance of p < 0.05. The findings of this study suggest that Evolvulus alsinoides may be a promising candidate for the development of new treatments for memory impairment and other cognitive disorders. It should be noted that more data is needed to confirm the safety and efficacy of Evolvulus alsinoides in humans and to investigate its long-term effects.

Biochemical analysis of methanolic extract from Evolvulus alsinoides.

Evolvulus alsinoides is a medicinal plant in the Convolvulaceae family. Traditionally, it is used for different ailments in India and in several other countries. It has a variety of pharmacological qualities, including those that aid wound healing, hepato-protection, cardio-protection, anti-diabetic action, asthma, and epilepsy, memory and learning, and neuroprotection. The whole plant is utilized in Ayurvedic medicine to treat neurological disorders, including amnesia, and it is called the brain tonic by them. Therefore, the use of GC-MS in phytochemical research and chemotaxonomic investigations of medicinal plants containing physiologically active components is critical. Hence, the various secondary metabolites from the methanolic extract of E. alsinoides were analyzed using GC-MS technique. The methanolic extract of E. alsinoides yielded ten compounds. All ten compounds showed the highest number of hits. Those with the highest concentration were chosen to identify the qualitative compound. All compounds are non-toxic. Molecules with specific properties are capable of modulating a variety of proteins, including some enzymes. Thus, these molecules are potential hit-to-lead molecules in preclinical studies.

Evaluation of analgesic and anti-inflammatory activity of a combination of tramadol-ibuprofen in experimental animals.

BACKGROUND: Pain is the major concern of patients attending dental clinics, and satisfactory pain relief has always been difficult to achieve. Since the pathophysiology of pain is a complex, central and peripheral nervous system process, combined analgesic regimens with different mechanisms of action as a multimodal approach are becoming popular among the clinicians and dentists. OBJECTIVES: The aim of the present study was to evaluate the analgesic and anti-inflammatory activity of ibuprofen and tramadol when used alone or in combination in animal models of pain and inflammation. ANIMALS AND METHODS: The animals were divided into six groups with six animals in each group. Analgesic activity was assessed by hot plate method in rats and by acetic acid-induced writhing test in mice. Paw edema model in rats after induction with 0.1 mL of 1% carrageenan was used to assess the anti-inflammatory activity. STATISTICAL ANALYSIS: Analysis of variance followed by Tukey's honestly significant difference post hoc test was used for statistical analysis. RESULTS AND CONCLUSION: Combined use of tramadol and ibuprofen provided enhanced analgesic and anti-inflammatory effects in animal models of pain and inflammation.
