Acmella oleracea (L.) R.K. Jansen (family Asteraceae) is an interesting plant because of its wide range of medicinal and culinary uses. It has been traditionally used in the treatments of anemia, body ache, cancer, gastric ulcer and infections, gingivitis, gout, inflammations, laceration, malaria, stammering, and worm infection (helminthiasis). Different extracts of the plants were prepared, and the methanol extract showed the highest number of bioactive compounds, including carbohydrates, phytosterols, and tannins. The antioxidant activity was estimated from the rate of scavenging of the free radical, 2,2-diphenyl-1-picrylhydrazyl (DPPH). The plant extract showed similar concentration-dependent scavenging activity as that of butylated hydroxytoluene (BHT). The total antioxidant activity was estimated against ascorbic acid, and it showed a higher value than BHT. The methanol extract was treated with two Gram-negative bacteria Pseudomonas aeuroginosa and Escherichia coli, and two gram-positive bacteria Staphylococcus aureus and Bacillus subtilis. However, no antibacterial activity was observed. Nonetheless, the study provides important information on the basic pharmacological properties of the...

Background: The whole plant of Argyreia pilosa Wight & Arn. (Convolvulaceae) continuously to be utilized in indigenous Indian systems as a remedy for cough, quinsy and applied externally in case of itch, eczema and other skin troubles, antidiabetic, antiphlogistic, rheumatism and reduce burning sensation. Still, there were constrained phytochemical or biological studies on the whole plant of A. pilosa, as well as no studies which align using its conventional medicinal uses. Aim: This study aimed to determine the total tannin and flavonoids contents, antimicrobial and antioxidant activity of two extracts of the whole plant of A. pilosa and compare them to find out the better extract for upcoming studies. Materials and Methods: The whole plant material was subjected to cold maceration with ethyl acetate and methanol to obtain ethyl acetate extract (APEE) and methanolic extract (APME). Phytochemical constituents of these extracts were determined as per standard procedure. Total phenolics had been estimated by the Folin–Ciocalteu colorimetric method using tannic acid as standard. Total flavonoids had been estimated by aluminium...

Aerva lanata has been used in traditional medicine for many years and used for the treatment of urinary bladder and kidney stones. The aim was to study the pharmacognostic characters and antimicrobial activity of important medicinal plant Aerva lanata (Amaranthaceae). The physicochemical, phytochemical and fluorescence analysis of powdered aerial and root parts of Aerva lanata was performed according to the standardization procedures recommended by the World Health Organization. The physicochemical parameters such as total ash, acid insoluble ash, water-soluble ash reveal that the plant has less amount of carbonates, silicates and are less affected by contamination and inorganic compounds. The various colors obtained by fluorescence were analyzed, and the moisture content of aerial and root parts were found to be 37.5%, 35.33% respectively. The preliminary phytochemical screening showed the presence of alkaloids, saponins, terpenoids, flavonoids, proteins, glycosides, coumarins, carbohydrate, steroids, tannins, phenols and phytosterols. The antimicrobial activity performed of Aerva lanata on Pseudomonas aeruginosa, Klebsiella pneumonia, Bacillus substilis, Streptococcus mutants, Escherichia coli, Staphylococcus aureus showed maximum activity against gram-negative...

The crude extract from the leaf of Canthium parviflorum Lam. in different solvents were subjected to physicochemical, fluorescence analysis, phytochemical and antimicrobial study. The microscopic analysis revealed that in C. parviflorum there is the presence of starch grains. The ash value was 5.81% in C. parviflorum. The fluorescent analysis at 366 nm of C. parviflorum powder extracted with alcohol showed orange-colored fluorescence with other it was no fluorescence. The extraction value with different solvents exhibited that C. parviflorum had maximum extractive value with chloroform followed by benzene, ethanol and petroleum ether. The phytochemical screening of the various extract of C. parviflorum revealed that the benzene extract showed the presence of alkaloids, tannins, flavonoids, saponins, and steroids. The chloroform extracts of the leaf showed the presence of alkaloids, tannins, flavonoids, saponins, and steroids. Anti-bacterial screening in C. parviflorum using stem revealed that the ethanol solvent showed maximum inhibition against gram-positive bacteria (Staphylococcus aureus) and chloroform solvent showed maximum inhibition in the case of gram-negative bacteria (Serratia...

Sulfated polysaccharides (SP) were extracted from Corallina officinalis marine red algae seaweed by using hydrothermal processes at 100 °C. The antioxidant activity of C. officinalis sulfated polysaccharide was determined using the (2,2-diphenyl-1-picrylhydrazyl, DPPH) method, showing that this polysaccharide has a moderate effect in inhibiting the formation of those radicals. This study demonstrates that sulfated polysaccharide obtained from marine red algae have the potential for use as natural antioxidants in industrial food...
