Abstract
Based on their high antioxidant capacity and noteworthy phytochemistry, Terminalia ferdinandiana fruit and leaves have attracted considerable recent interest for their therapeutic potential. Whilst those studies have reported a variety of therapeutic properties for the fruit, the anti-inflammatory potential of T. ferdinandiana has been largely neglected and the leaves have been almost completely ignored. This study investigated the immune-modulatory and anti-inflammatory properties of T. ferdinandiana fruit and leaf extracts by evaluating their inhibition of multiple pro- and anti-inflammatory cytokines and chemokines secretion in lipopolysaccharide (LPS)-stimulated and unstimulated RAW 264.7 macrophages using multiplex bead immunoassays and ELISA assays. The methanolic extracts were particularly good immune-modulators, significantly inhibiting the secretion of all the cytokines and chemokines tested. Indeed, the methanolic extracts completely inhibited IL-10, IFN-γ, IL-1β, IL-6, MCP-1, and MIP-2a secretion, and almost completely inhibited the secretion of TNF-α. In addition, the methanolic T. ferdinandiana extracts also significantly inhibited cytosolic COX-2 levels (by 87-95%) and the synthesis of the PGE2 (by ~ 98%). In contrast, the methanolic extracts stimulated LTB4 secretion by ~ 60-90%, whilst the aqueous extracts significantly inhibited LTB4 secretion (by ~ 27% each). Exposure of RAW 264.7 cells to the methanolic T. ferdinandiana extracts also significantly down-regulated the cytosolic levels of NF-κB by 33-44%, indicating that the immune-modulatory and anti-inflammatory properties of the extracts may be regulated via a decrease in NF-κB transcription pathways. Taken together, these results demonstrate potent anti-inflammatory properties for the extracts and provide insights into their anti-inflammatory mechanisms.

Abstract
Australian native plants have adapted themselves to harsh climatic conditions enabling them to produce unique and high levels of secondary metabolites. Native fruits and vegetables have been an integral part of the Indigenous Australian diet and Bush medicine for centuries. They have recently gained popularity owing to their rich dietary fiber, minerals, polyphenolic and antioxidant contents. This review presents a comprehensive summary and critical assessment of the studies performed in the last few decades to understand the phytochemical and nutritional profiles and therapeutic properties of Australian native fruits and vegetables. Furthermore, the potential of these fruits and vegetables as functional food ingredients and in the prevention and treatment of different diseases is discussed. Research on the nutritional and phytochemical profiles and therapeutic activity of Australian vegetables is limited with most studies focused on native fruits. These fruits have demonstrated promising antioxidant, anticancer, anti-inflammatory and antimicrobial activities mostly in in vitro models. More research to a) identify novel bioactive compounds, b) define optimal post-harvest and extraction methods, and c) understand molecular mechanisms of pharmacological activity through preclinical and clinical studies is prudent for the prospective and wider use of Australian native fruits and vegetables by the food, pharmaceutical, and nutraceutical industries.

Abstract
Bark from the Handroanthus impetiginosus (Mart. ex DC.) Mattos (Bignoniaceae) tree has long been used in traditional South American healing practises to treat inflammation. However, its anti-inflammatory activity has not been closely examined. Here we use chemical extraction, qualitative phytochemical examination, toxicity testing and quantitative examination of anti-inflammatory activity on human cells ex vivo. All extracts were found to be nontoxic. We found different extracts exhibited unique cytokine profiles with some extracts outperforming a positive control used in the clinic. These results verify the immunomodulatory activity of Handroanthus impetiginosus (Mart. ex DC.) Mattos (Bignoniaceae) tree bark-derived compounds. Collectively, combining a lack of toxicity and potency in human immune cells supports further fractionation and research.

Abstract
Traditionally, preservatives have been used in cosmetic products to minimize bacterial contamination. Some opportunistic Corynebacterium spp. have become resistant to these preservatives and other alternatives are required. A potential candidate is Conifer Green Needle Complex (CGNC), a pharmaceutical-grade complex substance from the green verdure of Pinus sylvestris and Picea abies with antibacterial, antimycotic, and antitrichomonal activity. The susceptibility of Corynebacterium xerosis and Corynebacterium flavescens to CGNC (3.5, 7, 15, 30, 60, 125, 250, and 500 mg/mL) was evaluated using broth dilution and agar methods. The antibacterial effect of CGNC was also evaluated after exposure for 30 minutes and 1, 3, and 24 hours at concentrations of 0, 3.5, 7, 30, 125, and 500 mg/mL. Corynebacteria xerosis was inhibited when exposed to low levels of CGNC (1560 mg/mL), whereas an antibacterial effect on C. flavescens was observed at slightly higher levels (60 and 125 mg/mL). CGNC also inhibited the growth of C. xerosis and C. flavescens at various incubation time points. The most prominent effect was observed after 24 hours where all growth was inhibited at all concentrations. However, CGNC inhibited or decreased the growth of Corynebacterium spp. even at lower exposure times. The results obtained in this study demonstrated that CGNC is an effective bactericidal agent against C. xerosis and C. flavescens isolated from clinical samples and may have potential as an alternative to preservatives currently used in cosmetic products.

Abstract
OBJECTIVE Recently, our group reported that extracts prepared from the Australian native plant Terminalia ferdinandiana Exell. are potent inhibitors of the growth malodorous bacteria with similar efficacy to triclosan and through these results, we highlighted a potential biological alternative to the current chemical additives. Other members of the genus Terminalia are also well documented for their antibacterial potential and tannin contents and thus were investigated as potential deodorant additives. METHODS Solvent extractions prepared from of selected Indian, Australian and South African Terminalia spp. were screened by disc diffusion and liquid dilution assays against C. jeikeium, S. epidermidis, P. acnes and B. linens. The antibacterial activity was quantified by liquid dilution MIC assays. The extracts were screened for toxicity using Atremia franciscana nauplii and HDF cell viability bioassays. High-resolution time-of-flight (TOF) LC-MS and GC-MS headspace fingerprint analysis was used to detect tannin, flavonoid and terpenoid components in the extracts. RESULTS Bacterial growth inhibition was observed in all Terminalia extracts with the methanolic T. chebula, T. carpenteriae and T. sericea extracts the most promising bacterial growth inhibitors, yielding MIC values as low as 200 µg mL-1 . Toxicity analyses of the extracts were favourable, and we determined that the methanolic T. chebula, T. carpenteriae and T. sericea extracts were all non-toxic. Using previously detected T. ferdinandiana antimicrobials as benchmarks, LC-MS and GC-MS fingerprint analyses revealed similar compounds in the methanolic T. chebula, T. carpenteriae and T. sericea extracts. CONCLUSION Through these results, we propose that Terminalia spp. extracts may be useful deodorant additives to inhibit the growth of axillary and plantar malodorous bacteria, offering a biological alternative to their chemically synthesized counterparts.

Inhibition of the growth of human dermatophytic pathogens by selected australian and asian plants traditionally used to treat fungal infections. J Mycol Med 2019; 29:331-344. [PMID: 31248775 DOI: 10.1016/j.mycmed.2019.05.003] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2019] [Revised: 05/29/2019] [Accepted: 05/29/2019] [Indexed: 11/22/2022]
Abstract
OBJECTIVE Syzygium australe (H.L. Wnddl. ex. Link) B. Hyland, Syzygium luehmannii (F. Muell.) L.A.S. Johnson, Syzygium jambos L. (Alston), Terminalia ferdinandiana Exell. and Tasmannia lanceolata (Poir.) A.C.Sm. are used in traditional Australian Aboriginal and Asian healing systems to treat a variety of pathogenic diseases including fungal skin infections, yet they are yet to be examined for the ability to inhibit the growth of human dermatophytes. MATERIALS AND METHODS The fungal growth inhibitory activity of extracts produced from selected Australian and Asian plants was assessed against a panel of human dermatophytes by standard disc diffusion and liquid dilution MIC methods. The toxicity of the extracts was evaluated by Artemia lethality and MTS HDF cell viability assays. The phytochemistry of the most promising extracts were examined by GC-MS headspace analysis and some interesting compounds were highlighted. RESULTS The aqueous and methanolic extracts of all plant species were good antifungal agents, inhibiting the growth of all of the dematophytes tested. The methanolic S. australe (SA) and S. luehmannii (SL) extracts were particularly potent fungal growth inhibitors. MIC values of 39 and 53μg/mL were recorded for the methanolic SL fruit extract against T. mentagrophytes and T. rubrum respectively. Similar MICs were also noted for the methanolic SL leaf extract (88 and 106μg/mL respectively). The methanolic SL leaf extract was a particularly good fungal growth inhibitor, with MIC values≤100μg/mL against the reference C. albicans strain (96μg/mL), E. floccosum (53μg/mL), and T. mentagrophytes (88μg/mL). This extract also produced MICs≤200μg/mL against all other fungal species/strains tested. Similarly good activity was seen for the methanolic S. australe leaf and fruit extracts, as well as the S. lehmannii fruit and S. jambos leaf extracts, with MIC values 100-500μg/mL. Interestingly, these extracts had low toxicity and high therapeutic indices, indicating their suitability for clinical use. GC-MS headspace analysis highlighted several monoterpenoids and sesquiterpenoids in the methanolic SA and SL extracts. T. ferdinandiana and T. lanceolata extracts also had promising antifungal activity, albeit with substantially higher MICs. CONCLUSION Whilst multiple extracts inhibited fungal growth, the methanolic S. australe and S. luehmannii leaf extracts and the S. luehmannii fruit extracts showed particularly potent activity against each of these dermatophytes, indicating that they are promising leads for the development of anti-dermatophytic therapeutics.
