TL;DR: I. coccinea flowers revealed the best antioxidant property, presenting much lower IC50 value than other extracts, and could be considered as a potential source of natural antioxidant.
Abstract: Objective: To investigate the in vitro antioxidant activity of methanol extracts of Ixora coccinea L. (Rubiaceae) flower, leaf and stem.Materials and methods: The 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity, total antioxidant capacity (TAC) and xanthine oxidase inhibition assay were carried out to evaluate the antioxidant potential of the extract. The IC50 values were calculated for the DPPH and xanthine oxidase assays in order to evaluate the antioxidant efficiency of each of the I. coccinea extracts. The phenol contents were also determined.Results: I. coccinea flowers revealed the best antioxidant property, presenting much lower IC50 value (6.6 mg/mL for DPPH assay). The flower extract showed a significantly higher antioxidant capacity compared to the other extracts. Furthermore, the highest phenolic content (polyphenols) was found in the flower extract (210.55 ± 6.31 µg GAE/mg extract). Moreover, I. coccinea extracts scavenged the superoxide radical generated by the xanthine/xanth...

TL;DR: Five Libyan medicinal plants Thapsia garganica, Hammada scoparia, Euphorbia serrata, Hyoscyamus albus and Retama rateam extracts are shown to be potential sources of natural antioxidant and antimicrobial ingredients favoring their possible use in industrial pharmacology on large scale.
Abstract: Five Libyan medicinal plants Thapsia garganica, Hammada scoparia, Euphorbia serrata, Hyoscyamus albus and Retama rateam were selected to evaluate their biological activities. Their total phenolic and flavanoid contents were assessed. The antioxidant activity was estimated using 2, 2-di- phenyl-1-picrylhydrazyl (DPPH) as free radical scavenger. Their crude extracts showed reducing potential proportional to their concentration. The correlation coefficient (R2) between antioxidant activity and their total phenolics and flavanoids content is 0.77 and 0.98 respectively. Crude aqueous, methanolic as well as alkaloids extracts of the five plants were tested against a number of G+ve and G-ve sensitive resistant (e.g MRSA) bacteria beside some fungal species. The aqueous extracts displayed weak antibacterial activity whereas methanolic extracts were profoundly effective against both G+ve and G-ve bacteria. The extracts of E. serrata and H. scoparia were highly effective against E. coli in particular. The alkaloid-rich extracts of H. albus and H. scoparia induced remarkable bacteriostatic and fungistatic effects. The bioactive ingredients of H. scoparia, E. serrata and R. rateam extracts are shown to be potential sources of natural antioxidant and antimicrobial ingredients favoring their possible use in industrial pharmacology on large scale.

TL;DR: Cold Aqueous, Methanolic, Ethanolic, and Ethyl Acetate extracts of dried leaves of all the four varieties of Piper betel at a final concentration of 500 mg/ml were tested against pathogenic microorganisms such as Pseudomonas aeruginosa, Staphylococcus aureus and Escherichia coli.
Abstract: The present study aims at a comparative study of antimicrobial properties of four varieties of Piper betel; namely Desawari, Desi, Bangladeshi and Jaleswar, cultivated in India. Cold Aqueous, Methanolic, Ethanolic, and Ethyl Acetate extracts of dried leaves of all the four varieties of Piper betel at a final concentration of 500 mg/ml were tested against pathogenic microorganisms such as Pseudomonas aeruginosa, Staphylococcus aureus and Escherichia coli using agar well diffusion method.

TL;DR: In this paper, the effects of humic acid (HA) and vermicompost on the herb yield and phenolic components of chicory aerial parts were evaluated under four HHA treatments (0, 0.6 and 0.9
Abstract: Chicory (Cichorium intybus L.) is one of the most important plants in the medicinal, nutritional and cosmetic industry. This study was conducted to evaluate the effects of humic acid (HA) and vermicompost on the herb yield and phenolic components of chicory aerial parts. Plants were grown under 4 humic acid treatments (0, 0.3, 0.6 and 0.9 kg/ hectare) and 4 vermicompost levels (0, 5, 7.5 and 10 t/ hectare) with three replications. Measurement of traits included fresh and dry yields of aerial parts, the IC50 and inhibition percentage of free radicals, the total and individual amounts of phenolics and flavonoids (caffeic, gallic, ellagic and p- coumaric acid, catechin, flavones and flavonols). Results show that humic acid and vermicompost improve the chicory yield and phytochemical properties such as the total contents of phenolics and flavonoids. The highest yield of dry aerial parts (20.29 g per plant) was achieved by 0.9 kg per hectare humic acid in combination with 10 t per hectare vermicompost. The highest total contents of phenolics and flavonoids were achieved when humic acid was applied at 0.9 kg/hectare in addition to vermicompost at 7.5 t/ hectare. The content of caffeic acid was highest among other phenolic components. The highest caffeic acid was achieved by treatments of 0.3 kg per hectare humic acid combined with 5 t per hectare vermicompost. The content of ellagic acid in shoots was highest when vermicompost was applied alone, by 5 t per hectare, with an average yield of 262.51 mg/100 g DW.

TL;DR: Vitex trifolia could afford significant protection against CCl4 induced hepatocellular injury and is supported by histological studies of liver tissue.
Abstract: Aqueous and ethanol extracts of leaf of Vitex trifolia was investigated for hepatoprotective activity against carbon tetrachloride induced liver damage. To assess the hepatoprotective activity of the extracts, various biochemical parameters viz., total bilirubin, total protein, alanine transaminase, aspartate transaminase and alkaline phosphatase activities were determined. Results of the serum biochemical estimations revealed significant reduction in total bilirubin and serum marker enzymes and increase in total protein in the animals treated with ethanol and aqueous extracts. However significant rise in these serum enzymes and decrease in total protein level was noticed in CCl4 treated group indicating the hepatic damage. The hepatoprotective activity is also supported by histological studies of liver tissue. Histology of the liver tissue treated with ethanol and aqueous extracts showed normal hepatic architecture with few fatty lobules. Hence the present study revealed that Vitex trifolia could afford significant protection against CCl(4) induced hepatocellular injury.
