Wound healing properties of Hylocereus undatus on diabetic rats

PHYTOTHERAPY RESEARCH, Issue 8 2005
R. M. Perez G.
Abstract Aqueous extracts of leaves, rind, fruit pulp and flowers of Hylocereus undatus were studied for their wound healing properties. Wound healing effects were studied on incision (skin breaking strength), excision (percent wound contraction) and the nature of wound granulation tissues, which were removed on day 7 and the collagen, hexosamine, total proteins and DNA contents were determined, in addition to the rates of wound contraction and the period of epithelialization. In streptozotocin diabetic rats, where healing is delayed, topical applications of H. undatus produced increases in hydroxyproline, tensile strength, total proteins, DNA collagen content and better epithelization thereby facilitating healing. H. undatus had no hypoglycemic activity. Copyright © 2005 John Wiley & Sons, Ltd. [source]

Antioxidant and cytoprotective properties of infusions from leaves and inflorescences of Achillea collina Becker ex Rchb.

PHYTOTHERAPY RESEARCH, Issue 4 2009

Abstract Plants are the main source of molecules with antioxidant and radical scavenging properties that aid the natural defence systems of cells and may be involved in the preservation of human health, particularly preventing all the physiopathological conditions where oxidative damage is a hallmark. Achillea collina Becker ex Rchb. is a medicinal plant of the Achillea millefolium aggregate (yarrow) traditionally used, particularly in mountain areas, as an infusion or alcohol extract for its digestive, antiinflammatory, analgesic, antipyretic and wound healing properties. The aim of this study was to investigate the antioxidant capacity and cytoprotective activity against oxidative stress of infusions obtained from the leaves and inflorescences of Achillea collina Becker ex Rchb., assessed by chemical (free radical scavenging activity by DPPH and Folin Ciocalteu assay) and biological assays (in vitro model of cytotoxicity and lipid peroxidation in PC12 cells line). Infusions of leaves had the highest antioxidant properties and cytoprotective activity. The antioxidant capacity was significantly correlated with the total phenolic content but not with the cytoprotective profile. Achillea collina Becker ex Rchb. has good antioxidant and cytoprotective properties, suggesting further investigations on its chemical composition and potential health value, particularly for traditionally prepared infusions of leaves.

AMINO ACID AND FATTY ACID COMPOSITION OF AN AQUEOUS EXTRACT OF CHANNA STRIATUS (HARUAN) THAT EXHIBITS ANTINOCICEPTIVE ACTIVITY

CLINICAL AND EXPERIMENTAL PHARMACOLOGY AND PHYSIOLOGY, Issue 3 2007

SUMMARY 1The present study was performed in order to determine the amino acid and fatty acid composition of an aqueous extract of the freshwater fish Channa striatus, obtained by soaking (1 : 2, w/v) fresh fillets overnight in a chloroform : methanol (2 : 1, v/v) solvent, to elucidate the mechanism responsible for its antinociceptive activity and to clarify the relationship between the presence of the amino and fatty acids and the expected activity. 2The aqueous extract was found to contain all amino acids with the major amino acids glycine, alanine, lysine, aspartic acid and proline making up 35.77 ± 0.58, 10.19 ± 1.27, 9.44 ± 0.56, 8.53 ± 1.15 and 6.86 ± 0.78% of the total protein, respectively. 3In addition, the aqueous extract was found to have a high palmitic acid (C16 : 0) content, which contributed approximately 35.93 ± 0.63% to total fatty acids. The other major fatty acids in the aqueous extract were oleic acid (C18 : 1), stearic acid (C18 : 0), linoleic acid (C18 : 2) and arachidonic acid (C20 : 4), contributing 22.96 ± 0.40, 15.31 ± 0.33, 11.45 ± 0.31 and 7.44,±,0.83% of total fatty acids, respectively. 4Furthermore, the aqueous extract was demonstrated to possess concentration-dependent antinociceptive activity, as expected, when assessed using the abdominal constriction test in mice. 5It is concluded that the aqueous extract of C. striatus contains all the important amino acids, but only some of the important fatty acids, which are suggested to play a key role in the observed antinociceptive activity of the extract, as well as in the traditionally claimed wound healing properties of the extract.
