Objective: The objective of the study was to evaluate the antibacterial, antioxidant, and in vitro wound healing property of Cocos nucifera tomentum. Methods: Ethanolic and methanolic extracts of C. nucifera tomentum were prepared using the Soxhlet extraction method and aqueous extract was prepared by the shaker flask method. These extracts were investigated for the phytochemical profile by gas chromatography and mass spectroscopy (GC-MS) and liquid chromatography-quadrupole-time-of-flight mass spectrometry (LC-Q-ToF MS), for antibacterial activity by microdilution method, for the antioxidant property by 2,2-diphenyl-1-picrylhydrazyl assay, and for in vitro wound healing activity on cell lines. Results: The preliminary phytochemical screening showed the presence of alkaloids, flavonoids, and various bioactive components. GC-MS and LC-Q-ToF MS analysis of extracts revealed the presence of bioactive compounds known to have wound healing properties as well as antioxidant and antimicrobial activities. The methanolic extract had better antibacterial activity against Proteus vulgaris and Escherichia coli, and better antioxidant and wound healing activity, when compared to the ethanolic and aqueous extracts. Conclusion: The present study suggests that C. nucifera tomentum might be a potential therapeutic source for topical antibacterial and wound healing applications.

The aim of study was to validate, by in vitro and in vivo studies, the traditional use for wound-healing activity of Artemisia absinthium L. Reversed-phase liquid chromatography coupled with diode array detection and electrospray ion trap mass spectrometry (RP-LC-DAD-ESI-MS) analysis allowed to identify eleven polyphenols with chlorogenic acid as the most abundant compound (3.75 g/100 g of dry extract). After that, antibacterial activity as well as acute dermal and oral toxicity were assessed in animal models. In order to investigate the wound-healing activity of A. absinthium methanol extract, two ointments were formulated (MEO 5% and 10%). The ointment with the highest concentration of plant extract (10%) showed a statistically significant effect on the rats wound contraction, similar to that exerted by the reference drug Cicatryl-Bio. Moreover, A. absinthium methanol extract showed the best antibacterial activity against the Gram-negative Escherichia coli ATCC 10536 (MIC 1.25–2.5 mg/mL) and the Gram-positive Staphylococcus aureus ATCC 6538 (0.31–0.625 mg/mL). The absence of oral and topical toxicity of the treated animals allowed to establish the safety of the ointments. Overall, data collected in the present study support and validate the use of A. absinthium as a wound healing agent in the Algerian traditional medicine.

Objective: Algae is the undisputed treasures of the sea and are a valuable raw material, providing unlimited opportunities for new drug discoveries. Marine algal products are in demand in the international market in the form of standardized algal extracts or semi-finished products. Methods: Aqueous and methanolic extracts of Oedogonium globosum and Oedogonium intermedium species were obtained maceration and hot percolation. The active principles from O. intermedium were isolated, purified by column chromatography, and characterized by spectral studies IR, λmax, 1HNMR and MS. The extracts of Oedogonium species were screened for their anti-microbial effects, acute dermal irritation and wound-healing activity studies. Results: Comparing to Oedogonium intermedium (45 %, 90 %, 87 %), very low extractive yields were obtained for Oedogonium globosum (10.80 %, 37 %, 28 %). At phytochemical screening, Terpenoids, Flavanoids and, Glycans were found to be present in a significant amount and upon their isolation, it was found that a collection of fractions from cold extract with Rf value in the range 0.32-0.34 as Glycans and those from the hot extract with 0.40-0.72 as Flavanoids and those from methanolic extracts with 0.23, 0.44 and 0.71 as for Terpenoids. Anti-bacterial study revealed out the fact of Oedogonium species could give higher inhibition to gram-positive than for gram-negative bacteria at (10 μg/10μl/disc) concentration. No symptoms of systemic toxicity and mortality were observed. Silver sulfadiazine, more potent in wound closure, the effect of methanolic extracts of O. intermedium (87 %) was almost at par to the standard (95 %) in action and significantly greater than O. globosum (72 %, P<0.05). Conclusion: Admittedly, Oedogonium type algal species can be known as medicinal algae with a plethora of a wide range of pharmacological activities. Thus, this research work may be considered further for extensive innovative discoveries of new lead molecules and any other pharmacological activities, in the future.

Conyza canadensis (L.) Cronquist (CCL) has been used by K’Ho minority in Bidoup Nui Ba national park, Lam Dong province, Vietnam as one of wound healing remedies. However, the scientific proof of treatment is still unclear. This study aimed to evaluate this wound healing potential of CCL. CCL power was extracted by ethanol and then partitioned consecutively with petroleum ether, ethyl acetate and water. Wound healing potential was evaluated by antibacterial activity, stimulation of fibroblast and keratinocyte proliferation. Agar-well diffusion was used in the antibacterial tests and the results showed that CCL had antibacterial activity against 02 dermatitis bacteria (Pseudomonas aeruginosa, Staphylococcus aureus) and 02 opportunistic infection bacteria (Escherichia coli, Enterococcus faecalis). Moreover, our results illustrated that CCL stimulated the fibroblast and keratinocyte proliferation compared to the control. Particularly, the fibroblast division increased 1.6 times at 31.25 µg/mL when treated by ethanolic extract, while ethyl acetate fraction showed 1.7 times increase at 10 µg/mL in keratinocyte proliferation compared to the control. Taken together, our study contributed scientific base of CCL in the wound healing.

Amf Inoculation

Arbuscular mycorrhizal fungi (AMF) are known to provide plant species with several benefits, such as an increased production of bioactive compounds. However, it is yet to be defined whether extracts of mycorrhizal plants are more efficient in vitro antibacterial actions when compared to non-mycorrhizal plants. We tested the hypothesis of whether or not, methanolic extracts of Libidibia ferrea fruits, from plants established in the field and inoculated with AMF, have higher antibacterial action when inoculated with Acaulospora longula, Claroideoglomus etunicatum or Gigaspora albida. In addition, native L. ferrea fruits collected from the Caatinga area were also tested. The extracts of L. ferrea fruits inoculated with A. longula had higher in vitro antibacterial action in relation to the extracts of fruits from non-inoculated plants (p <0.05) thus characterizing the first record of different antibacterial actions of plant extracts due to inoculation with AMF. The extracts of L. ferrea fruits inoculated with A. longula were more efficient in inhibiting growth of Gram-negative bacteria. The zone diameters of inhibition ranged from 2.48 % to 7.56 % larger than the zones of the non-inoculated L. ferrea fruit extracts. The inoculation of L. ferrea with AMF may represent an alternative way of producing fruits with different antibacterial activity.

Honey and propolis are natural substances produced by Apis mellifera that contain flavonoids, phenolic acids, and several other phytochemicals. The aim of this study was to phytochemically characterize three different types of honey and propolis, both separately and mixed, and to evaluate their wound-healing activity. Total phenolic compounds and flavonoids were determined using the Folin–Ciocalteu’s and aluminum chloride colorimetric methods, respectively. The antioxidant activity was evaluated by both the DPPH free radical scavenging assay and β-carotene bleaching test, and the anti-inflammatory activity was determined by a protein denaturation method. To evaluate the wound-healing activity of the samples, NHDF cells were subjected to a wound scratch assay. The obtained results showed that dark-brown honey presents a higher concentration of phenolic compounds and flavonoids, as well as higher antioxidant and anti-inflammatory activities. Propolis samples had the highest concentrations in bioactive compounds. Examining the microscopic images, it was possible to verify that the samples promote cell migration, demonstrating the wound-healing potential of honey and propolis.
