Aggravation of cyclophosphamide-induced reproductive toxicity in mice by aqueous extract of Aegle marmelos (L.)

Aegle marmelos (L.) (Rutaceae) commonly known as bael is an important medicinal fruit tree. The present study focused on the effects of aqueous extract of Aegle marmelos (AEAM) on the testis and sperm characteristics induced by cyclophosphamide (CPA) in mice. Thirty six adult Parke’s strain mice were divided into six groups: group I given only distilled water (control); group II administered with AEAM alone once in a week for five weeks; group III administered with CPA (200 mg/kg b.w., intraperitoneally) once in a week for five weeks and group IV-VI CPA along with AEAM (400, 500 and 600 mg/kg b.w., orally). CPA was found to reduce gonadosomatic index (GSI), sperm counts, motility, viability, antioxidant activities and induced histopathological changes of testis. In the group administered AEAM with CPA an exacerbation of sperm count, motility and viability of the cauda epididymis, GSI, antioxidant activities and architecture of testis was observed. The results suggest that the administration of AEAM may aggravate CPA-induced reproductive toxicity. It may be helpful in preparation of natural male contraceptives

Toxicity assessment of the alcoholic leaves extract of Reinwardtia indica

The present study aimed to evaluate the safety of the alcoholic leaves extract of Reinwardtia indica in Charles foster rats through an acute and sub-acute oral administration.For assessment of acute oral toxicity test, ratswere orally treated with single dose of the alcoholic leaves extract of Reinwardtia indica at the doses of 50, 250, 500, 1000 2000 and 5000 mg/kg. In sub-acute toxicity study, using the OECD guidelines no. 407, the extract was administered at the doses of 50, 250, 500, 1000, 2000 mg/kg/day for 28 consecutive days and at the dose of 2000 mg/kg satellite group also used for 6 weeks.In acute toxicity above mentioned doses neither showed mortality nor exterior signs of toxicity. In sub-acute, study no significant changes found in haematological and biochemical level ofthe treated rat after 14 days and 28 days in comparison to control. The histopathology of rat brain, kidney, liver, and heart also showed the no cellular changes after extract treated rat.The alcoholic leaves extract of Reinwardtia indica was found non-toxic in single drug dose administration up to 5000 mg/kg (acute study) and in sub-acute administration up to 2000 mg/kg

Aegle marmelos leaves protect Liver against Toxic effects of Cyclophosphamide in mice

Abstract: The present study was conducted to evaluate the phytochemical screening of leaves of A. marmelos and the hepatoprotective activity of aqueous extract of Aegle marmelos (AEAM) against CPA-induced liver damage in mice. AEAM (400, 500, and 600 mg/kg bw, orally) and CPA (200 mg/kg bw, intraperitonially) were administered to mice for 5 weeks, once a week. Silymarin (100 mg/kg bw) was given as reference standard. Serum glutamate oxaloacetate transaminase, serum glutamate pyruvate transaminase, alkaline phosphatase, acid phosphatase, bilirubin, cholesterol levels, and lipid peroxidation were significantly increased, accompanied by a significant decrease in the level of albumin in CPA-induced hepatotoxic group of mice compared to the control. However, significant amelioration in these parameters was found in AEAM treated groups of mice. CPA treatment markedly decreased the level of superoxide dismutase and catalase in the liver as well as white blood cells and red blood cells counts, which were significantly enhanced by AEAM treatment. Histopathological examinations have also confirmed the protective efficacy of AEAM. The phytochemical screening of the extract revealed the presence of alkaloids, saponins, tannins, flavonoids and phenols, which may have hepatoprotective role. Hence, the results of the present study indicated that AEAM may be effective as a hepatoprotectant in CPA-induced toxicity

Antioxidant Property of Aerial Parts and Root of Phyllanthus fraternus Webster, an Important Medicinal Plant

In present study free radical scavenging potential of aerial parts and root of Phyllanthus fraternus was investigated. Extraction was done in water and ethanol. Total antioxidant capacity was measured by DPPH free radical scavenging method; ethanolic extract of aerial part was most potent in activity with 50% inhibition at 258 μg/mL concentration. Lipid peroxidation (LPO) was measured in terms of thiobarbituric acid-reactive substances (TBARS) by using egg-yolk homogenates as lipid-rich media with EC50 of aerial part (ethanolic) 1522 μg/mL which was found to be most active. Superoxide (SO) radical scavenging activity was measured using riboflavin-light-nitroblue tetrazolium assay. Ethanolic and aqueous extract of both aerial part and root was almost similar in superoxide radical scavenging activity. Reducing power was determined on the basis of Fe3+-Fe2+ transformation in the presence of extract. Total phenolic and flavonoid contents were also measured by spectroscopic method. Results showed that the ethanolic fraction of aerial part is most active towards antioxidant potential and this activity is related to its polyphenolic content and reducing potential. Thus, P. fraternus extract can be used as potent natural antioxidant

Assessment of antioxidant potential in seed extracts of Nyctanthes arbor-tristis L. and phytochemical profiling by Gas Chromatography-Mass Spectrometry system

The present study has been carried out with the seed extracts of&nbsp;Nyctanthes arbor-tristis&nbsp;L. (Parijat) and evaluates its antioxidant potential and profiling the phytochemical constituents by Gas Chromatography-Mass Spectrometry (GC-MS) analysis. The antioxidant potential of the seed extracts was measured by four different&nbsp;in vitro&nbsp;assay like 2, 2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging activity, superoxide anion free radical scavenging activity, ferric reducing antioxidant power (FRAP) and lipid peroxidation inhibition potential (LPIP) assay. The total phenol content (TPC) and total flavonoid content (TFC) were estimated. The ethyl acetate extract (EAE) of seeds showed potential DPPH free radical scavenging activity (EC50&nbsp;129.49±3.55µg/ml), superoxide anion radical (EC50&nbsp;969.94±8.03µg/ml) and LPIP (EC50&nbsp;452.43±5.07 µg/ml) activities. The total phenol content was maximum in aqueous extract (AQE) which was 201.00±0.20 µg/mg gallic acid equivalent. The EAE was rich with total flavonoid and it was found to be 34.50±0.40 µg/mg rutin equivalent. The EAE was subjected for phytochemical-profiling using GC-MS system. The presence of different phytoconstituents supports the medicinal value of the seeds. The results suggest that EAE constitutes a promising new source of novel compounds. Further, it can be used for isolation and purification of specific compounds which have good antioxidant activities and possess useful biological activities

Efficient Catalytic Degradation of Selected Toxic Dyes by Green Biosynthesized Silver Nanoparticles Using Aqueous Leaf Extract of Cestrum nocturnum L.

In the present study, the catalytic degradation of selected toxic dyes (methylene blue, 4-nitrophenol, 4-nitroaniline, and congo red) using biosynthesized green silver nanoparticles (AgNPs) of Cestrum nocturnum L. was successfully performed. These AgNPs are efficiently synthesized when a reaction mixture containing 5 mL of aqueous extract (3%) and 100 mL of silver nitrate (1 mM) is exposed under sunlight for 5 min. The synthesis of AgNPs was confirmed based on the change in the color of the reaction mixture from pale yellow to dark brown, with maximum absorbance at 455 nm. Obtained NPs were characterized by different techniques, i.e., FTIR, XRD, HR-TEM, HR-SEM, SAED, XRD, EDX, AFM, and DLS. Green synthesized AgNPs were nearly mono-dispersed, smooth, spherical, and crystalline in nature. The average size of the maximum number of AgNPs was 77.28 &plusmn; 2.801 nm. The reduction of dyes using a good reducing agent (NaBH4) was tested. A fast catalytic degradation of dyes took place within a short period of time when AgNPs were added in the reaction mixture in the presence of NaBH4. As a final recommendation, Cestrum nocturnum aqueous leaf extract-mediated AgNPs could be effectively implemented for environmental rehabilitation because of their exceptional performance. This can be utilized in the treatment of industrial wastewater through the breakdown of hazardous dyes
