Background: Alzheimer’s disease (AD) is a progressive neurological disorder that develops with aging.Objective: In this research, we have examined the anti - Alzheimer’s effect of ethanolic extract from roots of Cassia occidentalis L. on colchicine-induced Alzheimer’s in Wistar rats.Methods: Ethanolic extract was obtained and spectroscopic, chromatography analysis was performed. Acute toxicity studies using Organization of Economic Co-operation and Development (OECD) Guidelines 423 were performed to examine and make sure that there were no signs of toxic effects. The induction of AD was done using colchicine which leads to symptoms like neurotoxicity, neuroinflammation, and neurodegeneration. In this experiment, a thorough analysis of body weight, behavioral parameters, locomotor activity, and biochemical evaluation was performed to estimate the medicinal properties of Cassia occidentalis Lin treating Alzheimer’s disease.Results: Pharmacognostic analysis showed the presence of vascular bundles, starch grains, fibers, calcium oxalate crystals, elongated parenchyma, and collenchyma mucilage as shown in the supplementary files. Locomotor activity, Escape latency time, Conditioned avoidance response, and Transfer latency were improved with treatment. Interleukin- 6 (IL - 6) levels were reduced significantly in the Colchicine + 200 Cassia mg/kg group (739.2 ± 0.37 pg/ml) than in the Colchicine Group (850.6 ± 0.40 pg/ml). Tumor necrosis factor (TNF-α) was decreased in the Colchicine + 200 Cassia mg/kg Group (1030.93 ± 0.51 pg/ml) than in the Colchicine Group (1455.06 ± 1.25 pg/ml). A significant decrease in total protein level was observed in the Colchicine Group (2.52 ± 0.10 mg/ml), (3.33 ± 0.90 mg/ml) as compared to Colchicine + 200 Cassia mg/kg Group (5.27 ± 0.09 mg/ml, (5.01 ± 0.10 mg/ml) respectively, in the Hippocampus and Entorhinal cortex. The levels of antioxidant enzymes such as Catalase (CAT), Serum superoxide dismutase (SOD), Reduced glutathione (GSH) and Malondialdehyde (MDA) were measured. When compared to the Colchicine Group (7.33 ± 0.16 nM/ mg, the MDA level was lower in the Colchicine + 100 Cassia mg/kg Group (3.20 ± 0.01 nM/ mg). The level of CAT in Colchicine + 200 Cassia mg/kg Group (7.01 ± 0.03 µmoles of H2O2/mg of protein) was seen to be increased when compared to Colchicine Group (3.32 ± 0.17 µmoles of H2O2/mg of protein). The level of SOD in Colchicine + 200 Cassia mg/kg Group (7.43 ± 0.02 U mg -1 of protein) was seen to be increased when compared with Colchicine Group (4.55 ± 0.03 U mg -1 of protein). The level of GSH in Colchicine + 200 Cassia mg/kg Group (10.07 ± 0.19 nM/mg -1 of protein) was increased when compared with the Colchicine Group (5.82 ± 0.11nM/mg -1 of protein). Histopathology of the Hippocampus and Entorhinal cortex showed diminished amyloid plaques, and neurodegeneration in the treatment groups.Conclusion: The present study showed that ethanolic extract from the roots of Cassia occidentalis L. At 100 and 200 mg/kg doses in Wistar rats improved memory damage, by reducing oxidative stress. Levels of the antioxidant enzymes as CAT, and SOD, GSH were increased and MDA was decreased. The cytokine levels in the serum of Wistar rats of IL-6 level and TNF-α level were reduced significantly. Estimation of total protein level was found to be increased. It restored neuronal degeneration in the Hippocampus, and Entorhinal cortex and reduced oxidative stress. This suggests that the ethanolic extract of Cassia occidentalis L. could be an effective therapeutic treatment for neurodegenerative diseases like AD.

Background: Tremors, psychological difficulties, mental health issues, depression, impulsive acts, and other behavioral abnormalities are all symptoms of Parkinson's disease, a neurodegenerative disorder of the central nervous system. Smilax chinaethanolic extract was tested for its anti-Parkinson's activity using a Wistar rat model of rotenone-induced Parkinson's disease. Spectroscopic, acute toxicity and pharmacognostic analyses were performed. Result: Brownish, the bark of Smilax chinaincluded vascular bundles and fibers upon microscopic inspection and alkaloids, carbohydrates, and phenolic substances upon phytochemical analysis. Acute toxicity testing as per Organization for Economic Corporation and Development 423 (OECD 423) on male Wistar rats revealed no harmful effects. The biochemical analysis of rotenone-induced groups revealed a disproportion. Improved body weight, mobility, coordination, and a lower incidence of catalepsy were seen in animals treated with Smilax chinaethanolic extract (100 and 200 mg/kg). Smilax china200 mg/kg extract substantially lowered motor defects determined by catalepsy score using bar test 17.061.74/s against rotenone-induced group 67.593.27/s. It also prevented the brain from oxidative stress by enhancing superoxide dismutase (SOD) levels to 5.440.01 units/mg protein compared to 2.050.104 units/mg protein in the rotenone-induced group. The vagus nerve, substantia nigra, and basal ganglia of the treated groups indicated a reduction in inflammation and alpha-synuclein destruction. Conclusion: Based on our research, an ethanolic extract of Smilax chinabark provides an effective antioxidant with promising neuroprotective properties in male Wistar rats induced with Parkinson's disease.

Phoenix dactylifera L (Date palm) belonging to family Arecaceae, called 'Nakhla' and the 'Tree of Life' by the Arabs, is considered as one of the oldest cultivated fruit trees. It is believed to be indigenous to the countries around the Arabian Gulf. Many Middle Easterners believe that consumption of date fruits, particularly in the morning on an empty stomach, can reverse the actions of any toxic material that the subject may have been exposed to. Different parts of this plant are traditionally claimed to be used for the treatment of a broad spectrum of ailments including memory disturbances, fever, loss of consciousness and nervous disorders. There has been a tremendous interest in this plant as evidenced by the voluminous work in last few decades. Therefore, we aimed to compile an up to date and comprehensive review of Phoenix dactylifera that covers its traditional and folk medicine uses, phytochemistry and pharmacology including various preclinical and clinical studies. Keywords: Phoenix dactylifera | Arecaceae | pharmacological activities | phytochemistry, Introduction The role of traditional medicines in the solution of health problems is invaluable on a global level. Medicinal plants continue to provide valuable therapeutic agents, both in modern and [...]
