“…Quercetin, gallic, salycilic, and ferulic acid solutions (4 mkg in every spot) were used as a reference. Plates were developed in 2% solutions of aluminum chloride, iron chloride, and phosphotungstic acid in ethanol (Sorescu et al, 2018;Shaikh and Patil, 2020). For a quantitative analysis of chemical constituents 120 mg of bark were poured into 1.5 mL of ethanol and extracted at 55 • C in an ultrasound chamber (Grad 80-35, Proton LLC, Moscow, Russia) for 35 min.…”

Diversity of secondary lichen metabolites was studied in epiphytic lichens on six phorophytes—spruce, pine, birch, alder, aspen and poplar in the Middle Urals of Russia. Atranorin, usnic, fumarprotocetraric acid, zeorin, and gyrophoric acid were found in 31, 24, 23, 18, and 14 species, respectively, of 237 taxa collected. Seventy-seven species (i.e., 32% of total species documented) contained no secondary metabolites. Spectra of secondary metabolites of fruticose and foliose lichens varied on different phorophytes, while in crustose species the strong dependence on the tree species was not detected. This is different to the pH dependence of saxicolous lichens where crustose lichens were more susceptible to the rock chemistry. The results of Canonical Correspondence Analysis reveal the affinity of species containing depsides, depsidones or usnic acid to acidic substrata and those lacking secondary metabolites or containing terpenes and antraquinones to the pH-neutral bark. We suppose that phenolic compounds and flavonoids, as chemical constituents of bark, may interact with lichen symbioses and elements in phellem, and similarly to the lichen acids shape the affinity of species to the substrata.

Background: The pod of Theobroma cacao is usually processed into a variety of beverages for human consumption; hence this study investigated its safety to vital organs at different doses. Method: Phytochemical, nutrient and antinutrient composition of unfermented theobroma cacao were determined using standard procedures. A total number of twenty-four (24) adult male Wistar albino rats (140 – 200g) were randomly divided into four groups of six rats each and were administered thus: Group I (normal control) rats were intraperitoneally administered with normal saline (1ml/kg b.w./day) for twenty-one days while group II, III and IV were intraperitoneally administered 200mg/kg, 400mg/kg and 600mg/kg b.w/day of Theobroma cacao for twenty-one days. During the course of the treatments, blood was extracted on days 0, 14, and 21 to determine the biochemical parameters including alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), while the liver and kidneys of the experimental animals were harvested for histopathological examinations at the end of the treatment. Results: The acute toxicity studies showed no toxicity up to 5000mg/kg of the extract. Treatment with the extract showed no significant difference (p>0.05) in the weight of the rats when compared with the control. A Significant decrease (p≤0.05) was observed in total bilirubin concentration and alanine aminotransferase (ALT) activity of the treated groups when compared with the control group while Aspartate aminotransferase (AST) activity showed a significant increase (p≤0.05) in some of the treated groups. The microscopic examination of the liver and kidney tissues showed no histopathological changes in the extract-treated groups. Conclusion: The observed results showed that unfermented Theobroma cacao is rich in antioxidants and has little or no toxicological effect on albino rats.

The Application of Aloe vera Gel as Coating Agent to Maintain the Quality of Tomatoes during Storage

et al. 2022

Aloe vera is widely used to manufacture medicinal products, cosmetics, and hair treatments. The polysaccharide components in A. vera gel can be used as ingredients for edible films or coatings. The edible film can also be applied to fresh fruits and vegetables using the coating principle. Tomatoes are one of the fruit commodities that can be maintained in terms of quality during storage using an edible coating. This study aims to determine the effect of an edible coating made from A. vera on tomatoes’ physical, chemical, and organoleptic properties during storage. The A. vera gel was prepared and used for coating the tomatoes, and the tomatoes were then stored for twelve days. The analysis was conducted every three days, and a comparison with non-coated tomatoes was performed for tomatoes’ physicochemical and organoleptic properties. The results show that the application of A. vera as a coating agent could prolong the shelf life of tomatoes, as described in the ability to decrease moisture content and weight loss. The coated tomatoes had lower titratable acidity value, pH, and total soluble solid contents than the non-coated tomatoes. From the organoleptic test, the non-coated tomatoes were preferred by the panelists for color, but the glossiness, skin appearance, and texture of the coated tomatoes were preferred. The coating process could maintain the hardness of tomatoes and prevent the production of phenolic compounds, flavonoids, and lycopene; thus, the antioxidant activity could be conserved.
