ResultsThe ethyl acetate fraction selectively showed the most suitable anti-AChE activity (IC50 = 99.69 µg/mL); none of the extracts or fractions demonstrated anti-BChE activity. In this regard, the ethyl acetate fraction was candidate for the investigation of further biological activities such as antioxidant activity, neuroprotectivity, and metal chelating ability related to Alzheimer’s disease. It depicted favorable neuroprotectivity at concentration of 100 μg/mL against the toxicity of exposure to H2O2 in PC12 cells (p£0.001, cell viability = 80/60%) and chelating ability towards zinc, iron, and copper ions. The results of antioxidant activity by DPPH assay showed that the ethyl acetate fraction was much more potent than BHA as the reference drug.ConclusionThe ethyl acetate fraction ofA. europaeum L. showed potent biological activities involved in Alzheimer’s disease and needs complementary investigations to develop an herbal product against Alzheimer’s disease.","PeriodicalId":21088,"journal":{"name":"Research Journal of Pharmacognosy","volume":"7 1","pages":"25-33"},"PeriodicalIF":1.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42724946","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study was aimed to investigate cytotoxicity, acute and sub-acute toxicity of hydroalcoholic extract of A. elburzense bulb. Methods Total phenolic content of the extract was measured using Folin-Ciocalteumethod. For cytotoxicity assay, human umbilical vein endothelial cells (HUVECs) were used. In acute toxicity study, single oral dose of 2000 mg/kg was administered in female and male Wistar rats and they were monitored for two weeks. In sub-acute test, 125, 250 and 500 mg/kg/day of extract were orally administered for four weeks. Results Total phenolic content was estimated as 32.8 ± 2.5 mg gallic acid equivalent/g of the extract. The extract showed IC50 value of 366.4 µg/mL (95% CI = 246.4-566.1) in HUVECs after 24 h exposure. In acute study, there was no sign of toxicity and no mortality; however, significant increase in relative spleen weight and ALP activity and mild inflammation in kidney tissue were observed. LD50 ˃ 2000 mg/kg was estimated for A. elburzense bulb extract. In sub-acute assay, there were significant elevations in relative spleen weight, blood urea level, AST, ALT, ALP, total WBC, lymphocyte and neutrophil count and significant decrease in blood sugar and triglyceride levels at higher doses of the extract.

The plant is known to have anti-hypertensive, anti-hyperlipidemic, anticancer, anti-diabetic and anti-inflammatory activities. For such a widely sold and used medicinal plant, it is important that simple but reliable parameters can be used to estimate the quality. This will reduce adulteration, improve quality and hence safeguard the consumer. This study was to examine simple parameters that can be employed to estimate the quality of dried whole and powdered samples of H. sabdariffa that are widely sold on the open West-African market. Methods: The parameters investigated were macroscopic, microscopic, phytochemical, physicochemical, microbiological, and fluorescence characteristics. Heavy metal and HPLC analyses were also performed. Results: The sepals of H. sabdariffa were dark red, united sepals alongside valvate aestivation. Phytochemical analysis showed the presence of saponins, tannins, alkaloids, flavonoids, and glycosides. It exhibited unique fluorescent profiles in various reagents. HPLC fingerprint showed 7 peaks eluting within 1 and 5 minutes. Arsenic, lead, mercury, and chromium were not detected but cadmium was detected which was within acceptable limits. The aerobic bacteria and fungi count were also within acceptable limits. Conclusion: These parameters can be used to evaluate the quality of dried sepals of Hibiscus sabdariffa sold on the open market before they are used in the manufacturing of beverages and medicines.","PeriodicalId":21088,"journal":{"name":"Research Journal of Pharmacognosy","volume":"7 1","pages":"55-63"},"PeriodicalIF":1.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46147947","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In Mali the efficacy and safety of “Sumafura Tiemoko Bengaly” an herbal tea based on A. mexicana aerial parts against malaria have been demonstrated. This study was aimed to investigate the pharmacognostic, physicochemical and phytochemical parameters of its aerial parts. Methods: Macroscopy, microscopy, chemo-microscopy, phytochemical, mineral and physicochemical analyses were performed using standard methods. Results: The macroscopy showed that A. mexicana is an herbal plant with prickly both on its greenish stem and the pinnatelobed leaves; the flower is terminal and yellow and the fruit is a capsule with thorns. The microscopy revealed the presence of epidermal cells with actinocytic stomata, calcium oxalate prism, lacticifers, palisade cells, vascular bundle, fibers and collenchyma cells in the fresh leaf and the dry aerial parts. The chemo-microscopy revealed the presence of lignins, tannins, starch, calcium oxalate, oils and proteins. Phytochemical screening revealed the presence of carbohydrates, alkaloids, tannins, flavonoids, saponins, sterols and triterpenoids. The physicochemical parameters as observed included moisture content (8.2 %); total ash value (16.7 %); acid-insoluble ash value (2.9 %); water-soluble ash value (4.8 %); ethanol - soluble extractive value (17.2 %) and water- soluble extractive value (34.3 %).

Methods : In order to prepare the required extract, aerial part of the Tanacetum was powdered (100 g) and macerated in 1 L of ethanol (80%) for 24 h. Twenty-four rats were randomly assigned to four groups: PTZ (sub-threshold dose 35 mg/kg for one month, intraperitoneal (i.p)), PTZ + phenobarbital (30 mg/kg, i.p), PTZ + Tanacetum extract (300 mg/kg, i.p), and PTZ + Tanacetum extract (600 mg/kg, i.p). Elevated plus maze (EPM), forced swim test (FST) and rotarod test were employed to assess the anxiety parameters, antidepressant and balance potential, respectively.
