AbstractFresh produces spoilage is a worldwide concern that accompany the global increase in food demand. Adverse human health and environmental effects of commercial spoilage control agents are major public concern. In this study, Prosopis juliflora leaves and fruit extracts had their antimicrobial activities evaluated against the growth of selected bacteria and yeast, and against mycelial growth and conidial germination of selected mycotoxins-producing fungi. P. juliflora water-soluble leaf ethanolic (PJ-WS-LE) extract with its novel extraction method showed the strongest antibacterial activity. Antimicrobial tests showed total inhibition of Botrytis cinerea, Alternaria alternata, Bacillus subtilis, Staphylococcus aureus and Candida albicans with MICs ranging between 0.125 and 1 mg/ml. Percent inhibition of mycelial growth (PIMG) of the extract was also determined against seven other fungal strains with highest value against Geotrichum candidum (66.2%). Even the least affected fungal strain showed alterations in their hyphae and spores exposed to PJ-WS-LE extract when observed using scanning electron microscope (SEM), alterations include exfoliated flakes, pores, vacuolation and applanation. Small-scale fruit bioassays controlled experiment showed high efficacy of the extract in protecting inoculated cherry tomato samples from B. cinerea and A. alternata infections. In conclusion, PJ-WS-LE extract is a feasible, natural antifungal agent that can replace common anti-spoiling chemicals.

Carpophores of Amanita muscaria (Fr.) S. F. Gray collected near Saskatoon, Saskatchewan, contained a mixture of orange-red, water-soluble pigments, none of which was identical with muscarufin, the red pigment reported in mushrooms of this species found in Europe. The main substances accompanying the pigments in the aqueous ethanolic extract were identified and the amounts of each estimated. Of these, fumaric and malic acids, glucose, trehalose, and mannitol have been reported in European specimens of the fungus. Gluconic and citric acids have not previously been described from this species. The composition of the lipid and free amino acid reserves was also determined.

Phytochemical Studies

The ancient wisdom in Ayurveda medicine is still not exhaustively explored. Multiple exotic plants existent in India which are not described in classical literature of Ayurveda are commonly referred to as Anukta Dravya (undocumented). Costus pictus D.Don is such a plant, recently introduced in India from Mexico, which is used for renal disorders there. In India, it is used in Diabetes mellitus. This is proven for antidiabetic, antioxidant, anticancerous, antimicrobial and diuretic actions. It is an easily propagated, palatable and cost effective plant. Identification through pharmacognostical and phytochemical studies is essential for the standardization of any plant. The green leaf is narrowly elliptic with 10 to 25cm length and 2.5 to 6cm width. Microscopy revealed presence of vascular bundles, unicellular trichomes in upper epidermis, thin walled parenchyma cells in ground tissue and layers of parenchymatous hypodermis. Powder microscopy showed presence of epidermal parenchyma cells with underlying chlorenchyma group of fibers and fibro vascular bundles.TLC photo documentation revealed presence of many phytoconstituents with different Rf values. Densitometric scan showed many peaks, 10 at 254nm, 11 at 366nm, 6 at 520nm and 9 at 620 nm after derivatisation. Moisture content was 20%. The percentage of total ash, acid insoluble ash, and water insoluble ash was determined. The water soluble extractive value was 22.57 which is highest among all the extracts. The results indicated the presence of alkaloid, steroids, tannins, flavanoids, phenol, carbohydrate and resin in ethanolic extract and steroid, flavanoids, phenols, saponins, tannins and glycosides in water extract.

A mixture of dimethyl sulfoxide (DMSO), glycerol, phytobland oil, and water (50:25:15:10, v/v) proved to be outstandingly effective as a carrier for water-soluble formulations of 4-amino-3,5,6-trichloropicolinic acid (picloram), (2,4,5-trichlorophenoxy)acetic acid (2,4,5-T), and mixtures thereof. The carrier was selected after numerous experiments in which these and other adjuvants, used individually, gave at least some degree of herbicidal enhancement on velvet mesquite seedlings [Prosopis juliflora var. velutina (Woot.) Sarg.]. Maximum synergism between the carrier complex and herbicide occurred with the triethylamine salt of 2,4,5-T; relatively little influence on the butoxyethanol ester was observed. Picloram and 3,6-dichloro-o-anisic acid (dicamba) were intermediate in activity between the two phenoxy formulations.

Ethanolic Extract Of Propolis

Propolis is a natural substance and consists of bioactive compounds, which gives it antioxidant and antimicrobial properties. However, the use of propolis is limited by the low solubility in aqueous solutions. Thus, nanoparticles may be likely to accomplish enhanced delivery of poorly water-soluble phytomedicine. The aim of the present study was to fabricate and evaluate the biological activity of ethanolic extract of propolis-loaded poly(lactic-co-glycolic acid) nanoparticles (EEP-NPs). The EEP-NPs were prepared using the oil-in-water (o/w) single-emulsion solvent evaporation technique. The physicochemical properties of EEP-NPs were characterized and tested on their cytotoxicity, antifungal activity, and impact on key virulence factors that contribute to pathogenesis of C. albicans. EEP-NPs were successfully synthesized and demonstrated higher antifungal activity than EEP in free form. Moreover, EEP-NPs exhibited less cytotoxicity on Vero cells and suppressed the virulence factors of C. albicans, including adhesion, hyphal germination, biofilm formation, and invasion. Importantly, EEP-NPs exhibited a statistical decrease in the expression of hyphal adhesion-related genes, ALS3 and HWP1, of C. albicans. The results of this study revealed that EEP-NPs mediates a potent anticandidal activity and key virulence factors by reducing the gene-encoding virulence-associated hyphal- adhesion proteins of C. albicans and, thereby, disrupting the morphologic presence and attenuating their virulence.

Abstract Ethanolic extracts of Propolis are used as antiinflammatory and wound healing drugs since ancient times. In order to facilitate a comparison of different extracts, the standardization on the basis of quantitative determination of prominent components of these extracts has been substituted for simple biochemical “activity” tests. One of these activity tests bases on the in­ hibition of peroxidase-catalyzed oxidation of indole acetic acid indicating the presence of a defined mixture of monophenolic and diphenolic compounds. Other tests (diaphorase-catalyzed reductions and xanthine oxidase-catalyzed oxidations) demonstrate significant radical scavenging properties. Water-soluble extracts of propolis exhibit higher antioxidative and inhibitory activities as compared to the ethanolic extract.

An electrospun hydrophilic non-water-soluble biocompatible polylactic acid (PLA) nonwoven material was used as a delivery system for propolis ethanolic extract (PEE) and silver nanoparticles (AgNPs) that are known for their established antiseptic and antimicrobial activity. Combination of PEE and AgNPs in a single product should provide efficient antimicrobial protection and improved wound healing. Evaluations of PEE and AgNPs on morphology of electrospun materials, release kinetics of AgNPs and phenolic compounds, antibacterial properties, and cytotoxicity of electrospun PLA materials were performed. The presence of PEE or/and AgNPs resulted in denser mats formed by thicker PLA fibers. The average diameter of PLA microfibers was 168±29 nm. The average diameter of microfibers increased to 318±40 and 370±30 nm when 10 wt% and 20 wt% ethanol were added, respectively. Addition of 10 wt% or 20 wt% PEE increased the diameter to 282±25 and 371±25 nm, respectively. Suspension of AgNPs also caused the formation of thicker microfibers with 254±25 nm diameter. Electrospun PLA microfibers with PEE maintained viability of HaCaT cells. Testing of antimicrobial activity confirmed the ability of AgNPs containing PLA electrospun materials to inhibit the growth of microorganisms.
