Hot Water Extract

Cosmeceutical formulations containing naturally derived active ingredients are currently preferred by consumers worldwide. Mushrooms are one of the potential sources for cosmeceutical ingredients but relevant research is still lacking. In this study, hot- and cold-water extractions were performed on four locally-cultivated mushrooms—Pleurotus ostreatus, Ganoderma lucidum, Auricularia polytricha and Schizophyllum commune—with the aim to assess the cosmeceutical potential of these mushroom fruitbody extracts. Total phenolics, polysaccharide and glucan content were determined. Antioxidant property of the mushroom extracts was assessed by determining the DPPH radical scavenging, ferric-reducing (FRAP) and superoxide anion (SOA) scavenging activity. Anti-hyaluronidase activity was used as an indicator for the anti-aging and anti-inflammatory property, while anti-tyrosinase activity was evaluated to assess the anti-pigmentation or whitening property of these extracts. Our results showed that total polysaccharide content of P. ostreatus extracts was the highest (235.8–253.6 mg GE/g extract), while extracts from G. lucidum contained the lowest glucan (10.12–10.67%). Cold-water extract from S. commune exhibited substantial tyrosinase inhibition activity (98.15%) and SOA scavenging activity (94.82%). The greatest hyaluronidase activity was exhibited by G. lucidum hot-water extract, with the value of 72.78%. The findings from the correlation analyses suggest that the cosmeceutical properties of these mushrooms can be attributed mainly to the combination of different types of compound such as polysaccharides and phenolics. Overall, cold-water extract of S. commune and hot-water extract of G. lucidum showed the best results and may be further investigated.

Hot Water Extract

Wine was produced from must formulated by mixing roselle calyces hot water extract with pineapple juice at ratios of 100:0, 90:10, 80:20, 70:30, 60:40, 50:50 for A, B, C, D, E and F respectively. Must were pitched with Saccharomyces cerevisiae, fermented at room temperature for 8 days followed by racking, pasteurization and ageing at room temperature for 31 days. The antioxidant capacity, mineral content and microbiological analyses were carried out on the musts and wine samples using standard procedures. There was a significant (p<0.05) difference between must and wines as fermentation was observed to increase its antioxidant capacity (2, 2-diphenyl -1- picrylhydrazylradical scavenging activity, ferric reducing antioxidant properties, trolox equivalent antioxidant properties and hydroxyl radical scavenging activity). Fermentation decreased the mineral contents (manganese, zinc and magnesium) of wines except for sodium that increased significantly. Values ranged from 3.81 – 7.77 mg/L for Manganese, 162.38 – 166.66 mg/L for sodium, 2.71 – 4.71 mg/L for zinc and 35.45 – 40.67 mg/L for magnesium. Microbial count was done at different stages of production and there was no detectable growth on cultured wine samples. The result of this study showed that wines of nutritionally high quality can be produced from blends of roselle hot water extract and pineapple juice.

A galactomannan and a branched (1 → 3)-β-D-glucan were isolated from the water hyacinth plant. The galactomannan, purified from the cold water extract, is composed of D-galactose and D-mannose in a ratio of 1.0:2.8. It has a (1 → 4)-linked D-mannose backbone, one out of three D-mannose residues being substituted with a single α-D-galactosyl unit. The branched (1 → 3)-β-D-glucan isolated from the hot water extract has a main chain composed of β-(1 → 3)-linked D-glucopyranosyl residues, and two single β(1 → 6)-D-glucopyranosyl groups attached as side chains to, on average, every 5 sugar units of the main chain. In addition, the branching of the β-glucan occurs regularly at O-6 of the β-(1 → 3)-linked backbone.

Glossogyne Tenuifolia

Glossogyne tenuifolia (Labill) Cass. (Compositae) is a special medicinal plant in the Pescadores Islands. Ethanolic, cold and hot water extracts were prepared from the dried herb and their antioxidant properties and components were studied. Ascorbic acid, α-tocopherol, butylated hydroxyanisole, citric and ethylenediaminetetraacetic acids were used in assays for comparison. With regard to EC50 values in antioxidant activity, ethanolic and hot water extracts (0.08 and 0.09 mg/ml) were much more effective than the cold water extract (0.76 mg/ml). At 1.0 mg/ml, reducing capacities were 1.57, 0.31 and 1.04 for ethanolic, cold water and hot water extracts, respectively. Scavenging abilities on 1,1-diphenyl-2-picrylhydrazyl radicals were in descending order: ethanolic > cold water > hot water extracts. At 20 mg/ml, the hot water extract chelated all hydroxyl ions (100%) whereas the scavenging ability of the cold water extract was 68.86%. Chelating abilities on ferrous ions were in descending order: cold water > hot water > ethanolic extracts. Phenols were found to be the major antioxidant components. All EC50 values were below 20 mg/ml, and some even below 0.1 mg/ml, indicating that all three extracts from G. tenuifolia were rich in antioxidant properties.

Hot Water Extract

This study is the first to show that increased mitochondrial activities improved the antiaging effects of Aloe vera leaf skin fermented by Lactobacillus plantarum on UVb-irradiated skin fibroblasts. The fermented extract (AF) increased the activities of mitochondrial reductase and the complex II and significantly reduced reactive oxygen species (ROS) production, even under UVb stress conditions, and also increased DPPH free radical scavenging activities compared with the hot water extract of outer layers of aloe leaf (AW) and quercetin itself. AF exerted a synergistic effect with quercetin and bioactive substances derived from the fermentation process. Moreover, mitochondrial activation of UVb-irradiated human skin fibroblasts by 0.3% (w/v) of the AF plays important roles in increasing collagen production up to 125 ± 5.45% and decreasing MMP-1 secretion down to 69.41 ± 2.63% of the control levels. The AF enhanced the upregulation of collagen gene expression, and this change was also greater than those induced by the AW and quercetin. Therefore, this study concludes that fermentation of the skin of aloe leaves increases the activation of mitochondria and inhibits the photo-aging of UVb-irradiated skin fibroblasts.

Hot Water Extract

Evaluation of the relative efficacy of powdered leaf extracts of Aloe vera (Linn) and Aloe schweinfurthii (Baker) in the control of some plant pathogens was undertaken in this work. Antimicrobial activities of the extracts obtained using cold water, hot water and ethanol were tested against four fungal spp., namely, Alternaria solani, Colletotrichum lindemuthianum, Sclerotium rolfsii and Trichophyton rubrum. The phytochemical screening of the leaf extracts of the two aloe species revealed the presence of bioactive compounds such as alkaloids, tannins, saponins, flavonoids, cardiac glycosides, phytates and oxalates. The extracts were observed to exhibit varying inhibitory effects on the selected fungi. Ethanolic extract of A. vera at 50 mg/ml and 100 mg/ml had the greatest impact on A. solani and C. lindemuthianum respectively. Similarly, cold water extract of A. schweinfurthii at 100 mg/ml was the most effective against S. rolfsii and T. rubrum. However, hot water extract of A. vera was least effective against C. lindemuthianum. Also, the efficacy of cold water extract of A. schweinfurthii at 50 mg/ml was very low against T. rubrum and A. solani. The hot water extract of A. schweinfurthii at 20 mg/ml also showed the least effect against S. rolfsii. Consequently, extracts from both Aloe species can be recommended in the management of the four fungal pathogens evaluated in this study. It is hoped that in no distant future, botanical fungicides would be developed from the two Aloe species.

This study was conducted to determine the antibacterial effect of crude extracts of Annona muricata, comparing the leaf and stem bark extracts using the same extraction solvents. The bacteria isolates were obtained from the hospital. The isolates obtained are Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumoniae, Proteus mirabilis and Streptococcus pyogene; they were confirmed using standard techniques. Multiple antibiotic-resistant was confirmed in the isolates after antibiotic susceptibility testing. Extracts were prepared from the leaf and stem of A. muricata using ethanol, chloroform, cold water and hot water. The antibacterial activities of the crude extracts were assayed using the agar well diffusion method. The phytochemical screening revealed the presence of saponins, Tannins and flavonoid especially in the ethanol extracts of both leaf and stem part of the plant. All the extract showed varying degrees of antibacterial activities. Chloroform and Hot water rated best for antibacterial activities in this study. A. muricata stem hot water extract has zones of inhibition that ranges from 16.003 ± 0.009 mm to 1.000± 0.006 mm. A. muricata leaf hot water extract has antibacterial effect with zones ranging from 14.500± 0.009 mm to 1.000± 0.006 mm across the isolates. Cold water extracts recorded the lowest zones of inhibition from this study for the stem and Bark antibacterial activities. The stem of A. muricata has higher inhibitory effect on the test isolates compared to the leaf of      A. muricata.
