Introduction: Elaeis guinenesis is a perennial monocot belonging to the family Arecaceae. It is the source of the oil commonly called African palm oil or macaw fat which in traditional medicine has many uses Aim: This study is focused on the pharmacognostic screening of oil of Elaeis guineensis, and its antidotal effect on cyanide poisoning. Method: The extracted oil was subjected to various screening technique in order to determine its quality, purity and chemical constituents. The oil was macroscopically examined; acute toxicity test of Elaeis guineensis oil was carried out on rats. The oil was subjected to heating to determine the moisture content. Phytochemical analysis was also carried out on the palm oil extract. The physicochemical analysis was carried to determine the acid value, saponification value, ester value, hydroxyl value and iodine value. The Ld50 for the pure cyanide was carried out on the rats using “Up and Down” method. The antidotal study of Elaeis guineensis oil was carried out on the rats. Result: Macroscopic evaluation showed, the oil was in fresh condition, smooth texture, bright red colour, characteristic taste, oily appearance and a characterictic smell. The Phytochemical analysis showed the presence of flavonoids, phenols, tannins, saponnins, alkaloids, steroids and terpenoids. The physicochemical analysis showed that the oil has an acid value of 31.2, Saponification value of 194.8, Ester value 163.54, Peroxide value of 18.0, Hydroxyl Percentage of 2.07% and Free Fatty Acid of 3.65. The moisture content was calculated to be 0.2%. For the acute toxicity test on the oil using Lorkes method no death was recorded. The LD50 of the cyanide carried out on the rats showed that the lethal dose of cyanide is 5 mg/kg. The antidotal effect of Elaeis guineensis oil showed the absence of death on the group given oil extract alone and the groups that were poisoned and given the oil (antidote) within 4 minutes. Deaths were recorded for the groups that were administered antidotes after 8 minutes. Conclusion: Elaeis guineensis oil has counteracting effect on cyanide poisoning if administered within four minutes of cyanide ingestion.

The Impact

Drying is one of the traditional means of preserving food. However, various drying methods can influence the nutritional and bioactive constituents of the food product. This study is aimed at evaluating the effect of different drying methods on the proximate composition, physicochemical properties, and minor constituents of palm oil fruit mesocarp. Two varieties of fresh oil palm fruit (dura and tenera) were processed to separate the mesocarp from the other part of the fruit. The fresh fruit mesocarp was divided into five groups and subjected to different drying methods. Proximate and physicochemical characteristics of the oil palm fruit mesocarp were determined. The dried mesocarp had low moisture content (1.49-3.28%), high crude fat content (78.10-90.60%), carbohydrate (4.41-15.12%), crude protein (0.93-3.40%), and ash (0.53-1.15%). The free fatty acid (FFA) (1.06-3.54) and acid value (AV) (2.17 to 8.83 mgKOH/g) were lower because the samples were heated at 100°C for 30 min. The lower pH, FFA, AV, titratable acidity, moisture content, and high antioxidant activity of the oil palm fruit products could be an indication of shelf stability against microbial contamination and rancidity.

<p>The current study was aimed to investigate the extracts from <em>Heliotropium strigosum</em> and <em>Trapa bicornis</em> phytochemically for various constituents and pharmacologically for gastro-intestinal disorders. Phytochemical analysis indicated the presence of alkaloids, flavonoids, glycosides and tannins in both the extracts. In castor oil-induced diarrhea, <em>H. strigosum</em> and <em>T. bicornis</em>, at 100-1000 mg/kg dose provided protection of 10-83% and 14-76% respectively. In isolated rabbit jejunum preparations, <em>T. bicornis</em> (0.01-5 mg/mL) relaxed the spontaneous and K+ (80 mM)-induced contractions with EC&lt;sub&gt;50&lt;/sub&gt; values of 1.2 mg/mL and 2.6 mg/mL respectively, suggesting that spasmolytic effect was possibly mediated through calcium channel blockade. This was further authenticated when pretreatment of tissues with <em>T. bicornis</em> (1-5 mg/mL) caused rightward shift of Ca++ concentration–response curves, similar to verapamil. In acute toxicity test, both extracts were safe up to 10 g/kg dose. These results indicated the usefulness of <em>H. strigosum</em> and <em>T. bicornis</em> in the treatment of hyperactive gut disorders.</p>

Palm oil is an edible vegetable oil, extracted from the fruit of the Elaeis guineensis which is used for frying foods in most of the restaurants and confectionaries as well as for cosmetic preparations in industries. As the quality of palm oil in Bangladesh is deteriorating day by day, ten brands (S-1 to S-10) of commercially available palm oils were collected from different local markets, their physicochemical properties were tested and compared with the standard parameters stated by Bangladesh Standards and Testing Institution (BSTI). Results revealed that the acid value, free fatty acid value and relative density of all the palm oils (S-1 to S-10) were within the range of BSTI standard. However, the saponification value, peroxide value, iodine value, insoluble impurities and moisture content were much higher than the ranges of BSTI standard in all the samples. Moreover, lead content was higher than the standard value (>0.1 ppm) in brands S-1, S-4 and S-10. In addition, Copper and Iron contents were higher than the BSTI standards (0.1 and 1.5 ppm) in all the tested samples, whereas Cadmium content was below than the standard level (1.0 ppm).

Hibiscus rosa-sinensis has been traditionally used by local communities to treat fever. However, there are only limited data have been published to support the antipyretic effects. The objective of this study is to investigate the antipyretic properties and possible mechanism of the ethanol extracts of Hibiscus rosa-sinensisL. (red colored flower) and Hibiscus rosa-sinensisvar. Alba (white colored flower). Phytochemical analysis, heavy metals screening and acute toxicity test were done to evaluate the safety of extracts. The first model ran induced fever in rats by injecting Brewer's Yeast subcutaneously and then treated with 4 extracts at dosage 5 & 50 mg/kg. The dosages used for the study were obtained by the acute toxicity test. Ibuprofen was used as a reference drug, with dose 100 mg/kg. Temperatures of rats were measured using a digital thermometer. The results were expressed as mean ± S.E.M. and analyzed using the SAS system. The results of the study showed that white flower extract 5mg/kg and 50 mg/kg significantly (p <0.05) reduced the total temperature when compared to positive control group. Therefore, this research suggests the probability for its therapeutic effectiveness as plant-based antipyretic agent as claimed by traditional medicine practitioners.
