A large variety of unique and distinct flora Australia have developed exceptional survival methods phytochemicals hence may provide a significant avenue for new drug discovery. This study proposes bioassay guided fractionation protocol that maybe robust efficient in screening plants with potential bioactive properties isolating lead novel compounds. Hence, five native Australian were selected this process, namely

Sesame is an emerging crop of interest in Australia and has attracted widespread due to the health-benefitting properties its bioactive compounds, including fatty acids, lignans, polyphenols. This study aimed investigate impact drought stress on these using eleven cultivars black sesame seeds grown Australia. Specific varieties responded positively water deficit (WD) conditions, showing increased levels TPC, FRAP, CUPRAC, lignans. Varieties 1, 4, 7, 12 showed significantly FRAP values...

Although Australia is the largest exporter of faba bean globally, there limited information available on levels bioactive compounds found in current commercial varieties grown this country. This study profiled phenolic acid and flavonoid composition 10 Australian varieties, at two different locations. Phenolic profiling by HPLC-DAD revealed most abundant to be catechin, followed rutin. For acids, syringic was high concentrations (72.4–122.5 mg/kg), while protocatechuic, vanillic,...

Ginger is well known for its pungent flavour and health-benefitting properties, both of which are imparted by various gingerol derivatives other volatile constituents. Although there has been a considerable amount research into the chemical constituents found in fresh ginger, little information available on quality Australian-grown dried particularly that intended processing purposes. Here, we investigate differences composition three samples processing-grade ranging from very poor to good...

The aim of the present study was to evaluate potential handheld near-infrared (NIR) and benchtop mid-infrared (MIR) spectroscopy for rapid prediction antioxidant capacity, dry matter, total phenolic contents in cayenne pepper (Capsicum annuum ‘Cayenne’). Using NIR spectroscopy, best-performing model matter had an R2pred = 0.74, RMSEP 0.38%, RPD 2.02, exceeding best results previously reported literature. This also first predict content from spectra, although with lower accuracy (R2pred 0.54;...

While plums are widely touted for their health benefits, there is little data available on the levels of beneficial anthocyanins and other antioxidative compounds found in commercial Australian plums. As such, this study aims to provide context typical variation consumers. Six plum varieties were sourced from Central Queensland grocery stores, including two developed grown exclusively Australia – Croc Egg "King Midas" yellow as well four both internationally: black, Dapple Dandy, red sugar...

The rum industry is currently worth USD 16 billion, with production concentrated in tropical countries of the Caribbean and Asia-Pacific regions. primary feedstock for sugar cane molasses, a by-product refineries. main variables known to affect quality include composition length fermentation, type barrels time used aging rum. goal this review provide an overview impact these on quality, highlight current challenges opportunities from molasses. In order achieve this, we relevant contemporary...

Sweet potatoes are experiencing increased popularity across many parts of the world due to their high levels functionally beneficial compounds, including vitamin C, anthocyanins and carotenoids. However, limited work has been performed on Australian-grown sweet potatoes. This investigated key phytochemical composition root tissue five Australian potato cultivars that grown commercially. The cultivar WSPF (White Skin, Purple Flesh) displayed highest total phenolic content, antioxidant...

Burdekin plum (Pleiogynium timoriense) is a widespread native edible fruit from Australia; however, there are limited studies exploring the chemical composition of this species. This study investigated phytochemical flesh and seeds, finding high antioxidant activity (12,571 mg Trolox equivalents/100 g as Ferric Reducing Antioxidant Potential), total phenolic content (10,928 gallic acid g) anthocyanin (161 cyanidin-3-glucoside in flesh. The seeds also displayed moderately (3,306 (2,344 g)....

Abstract The edible, endemic Australian species Alpinia caerulea belongs to the same family as ginger and turmeric. rhizome fruit have a mild ginger-like flavour, but there is very little information on its chemical composition or potential biological activities. This study found low levels of ascorbic acid in capsule (2.3–3.4 mg/100 g fresh weight), well detecting six polyphenols (rutin, quercetin-3-glucoside, quercetin, vanillic acid, kaempferol chlorogenic acid) across all plant parts....

Abstract Four new lines of mungbean cultivated under northern Australian cropping conditions (19.8462°S, 147.2448°E) were characterised for yield, seed characteristics, nutritional contents, phytochemical profiles and phenolic acid contents. Their performance was compared to a commercially grown line (Jade‐AU). The yield three the (AVTMB 1, 3 4) 14% higher Jade‐AU. However, size AVTMB 1 also significantly smaller other in vitro sprouting acceptability scores ranged between 80% 100%, with no...

Numerous commercial pharmaceuticals – including anticancer, antiviral, and antidiabetic drugs have been developed from traditional plant-derived medicines. There are approximately 25,000 species of flora occurring in Australia, which adapted to a range harsh environments, hence plethora novel compounds still awaiting research the context their medicinal properties. The current study therefore aimed develop systematic protocol for screening plants with potential cytotoxicity. Many studies...

Background and Aims The concentration of free trans-resveratrol in wine is expected to increase with storage because hydrolysis piceid (a bound form resveratrol). This study measured resveratrol 16 Australasian red wines ranging from 1 6 years old, both initially after a period months under ambient conditions. Methods Results During the period, decreased by an average 76%. decay was first order over tested range source vintage, mean bottle-storage half-life 8 (±1 SD) months. Decay rate...

Microplate-based methods are commonly used to conduct spectrophotometric-based assays on large batches of sample extracts as they allow much greater throughput compared traditional benchtop methods. However, many reported have not undergone a thorough method development/optimisation process; thus, the significance maintaining certain parameters and procedures is often unknown. This study investigated importance plate shaking prior absorbance measurement step in two common assays: total...

The production of high-quality rum requires a carefully controlled fermentation process, which is determined by the physicochemical and nutritional properties molasses used as substrate. flavor, aroma, alcohol content final product are heavily influenced composition molasses. This paper presents results an extensive analysis molasses, byproduct sugar that has various applications in food feed industries. were investigated using range analytical techniques including Brix, moisture content,...

Bioprospecting native Australian plants offers potential discovery of latent and novel bioactive compounds. Promising cytotoxic antibacterial activity methanolic extracts Pittosporum angustifolium Terminalia ferdinandiana led to further fractionation isolation using our laboratory’s bioassay guided protocol. Hence, the aim this study was evaluate bioactivity fractions subfractions characterize compounds liquid chromatography mass spectroscopy (LC-MS/MS) gas MS (GC-MS). Compounds tentatively...
