New Bioinsecticides From Combination Extract of Leaf and Flower of Breadfruit (Artocarpus Altilis) On Mortality of Aedes Aegypti Larvae

The main vector for the spread of dengue fever is the female mosquito Aedes aegypti. In Indonesia, chemical larvicides are commonly used to control Aedes aegypti larvae. Bioinsecticides made from plants are one option for environmentally friendly larvae control. Leaves and flower of breadfruit Artocarpus altilis contains toxic compound that can function as larvicides. This experimental study used combination of leaf and flower of breadfruit expect that the combination of the two extracs was synergistic and it was more effective in killing Aedes aegypti larvae. The third instar Aedes aegypti larvae was used and divided into control group and test group with concentrations 1000, 2750, 4500, and 6250 ppm and replicated in 3 times with observations every 6, 9, and 24 hours. To identify the significant difference, the mortality data was analyzed using ANOVA and Duncan's test. In probit analysis, LC50 value of breadfruit leaf extract was 1871 ppm with LT50 was 4.2 hours. LC50 value of breadfruit flower extract was 2531 ppm with LT50 was 10.8 hours. LC50 value of the combination of breadfruit leaf and flower extract was 903 ppm with LT50 was 3.7 hours. Based on these studies, it may be indicated that breadfruit leaves and flowers was more effective in killing Aedes aegypti larvae than single extracts

SCALILA SURPRISE HAND SOAP: THE HERBAL SOAP CREATION OF BREADFRUIT LEAF SOLUTION FOR ROUTINE HAND WASHING FOR CHILDREN

The number of trees or breadfruit plants in West Sumatra increases every year. Currently the only part of the breadfruit tree that is widely used is the fruit, while the leaves are underutilized and only become waste. Breadfruit leaves contain flavonoids, alkaloids, saponins, and tannins which function as antibacterial. Based on these data, breadfruit leaves, which were originally only used as waste, can be innovated into a new breakthrough, namely the main ingredient for making soap. In addition, as we all know, it is very important to regularly wash our hands with soap, especially during a pandemic like today.

Development of Gluten‐Free Muffins made from Breadfruit and Unripe Plantain Flours

AbstractInclusion of breadfruit (BF) and unripe plantain (UP) in gluten‐free muffins was investigated along with a 1:1 BF/UP blend muffin and compared to controls made with gluten‐free rice (RI) or traditional wheat (WH) flour. The alternative flours had a 10% higher fibre content than WH and 2%–4% higher than RI flours. Muffin batter viscosity of RI and WH was initially much lower (3‐10 times) than UP, BF and BF/UP blend batter. Additionally, starch gelatinisation temperature was increased by 4%–14% for batter made from BF or UP flours, which can provide structural benefits to baked muffins. Muffins made with BF/UP were the hardest (34.7N), followed by BF (31.7N) and RI muffins (30.7N), with UP (28.4) and WH muffins (26.9N) being the softest. Interestingly, overall acceptability of gluten‐free muffins showed that both BF/UP and BF flour muffins scored significantly higher than UP and RI muffins indicating their commercial potential.

Effect of acid catalyst on pyroconversion of breadfruit ( Artocarpus altilis ) starch: Physicochemical and structural properties

This work produced pyrodextrins from breadfruit (Artocarpus altilis) starch and evaluated the effect of HCl and CH3COOH as catalysts of pyrodextrinization on physicochemical and structural properties of pyrodextrins. Pyroconversion was performed by spraying the acid solution on starch (1.82 g acid/kg starch) and heated to 140°C for 180 min. The pyrodextrins were analyzed for chemical composition, dextrose equivalent (DE), color parameters, solubility, intrinsic viscosity, infrared spectrum, and granule morphology. The pyroconversion decreased (p < .05) the ash content and the intrinsic viscosity of native starch. The HCl-pyrodextrin was slightly yellow, very water soluble with 8.8% DE. The CH3COOH-pyrodextrin was white, 8.8% soluble with 1.2% DE. The pyrodextrinization reduced α(1,4) bonds of glucans without drastically changing the granule’s morphology. The use of acetic acid was considered a milder treatment, however, it caused an increase in the total and soluble dietary fiber contents, supporting its use to produce pyrodextrins for food applications. Novelty impact statement This article provides the first report of pyrodextrinization of breadfruit (Artocarpus altilis) starch. The HCl as catalyst caused greater changes in starch properties than acetic acid. The acetic acid caused a 10% increase in the total and soluble dietary fiber contents of pyrodextrin.

In vivo Chemosuppressive effects of Combinations of Three Nigerian Ethnomedicinal Antimalarial Plants

Aims: Appropriate ratios for combining some African ethnomedicinal plants with proven anti-plasmodial activity were determined with the aim of obtaining herbal remedies with higher efficacies.&#x0D; Place and Duration of the Study: Study was conducted in the Department of Pharmacognosy, Obafemi Awolowo University, Ile-Ife Nigeria.&#x0D; Study Design: Infusions of dried powders of three Nigerian ethnomedicinal plants, Eugenia uniflora leaf, Gongronema latifolium root and stem and Artocarpus altilis stem bark, were separately evaluated and in varied combination ratios for their anti-plasmodial activities&#x0D; Methodology: The infusions were separately prepared, concentrated in vacuo, freeze-dried and evaluated at 400mg/kg against Plasmodium berghei berghei parasites, using the Peter’s four-day chemosuppressive mice model. Normal saline and chloroquine (10mg/kg) were negative and positive controls, respectively. 2- and 3-combinations of the infusions were similarly tested.&#x0D; Results: Of the 2-plant combination ratios, 1:1, 1:3, 2:3 of EG and GA elicited percentage chemo suppressions which were comparable (P=.28; P=.07) to those of the single drugs. Only the EG ratios gave activities that were comparable (P=.28) to the positive control in addition to double survival times and high survivor values by EG 2:3 and GA 1:3. However, those of the EA group, gave relatively low values, barely above 20% with only the ratios 2:3 and 3:2 giving values which were significantly (P=.00) higher than negative control with double survival times. The 3-plant combination ratios, EGA 2:1:2 and 3:3:2 gave suppressions that were significantly (P=.00) higher than the negative control with others but comparable (P=.33) activities to those of the individual drugs. The other ratios with low suppression values were relatively inactive. But three ratios, EGA 3:1:2, 2:1:1, 1:1:1 elicited survival times doubled (204, 242 and 202 %) that of the negative control without commensurate high antiplasmodial activities.&#x0D; Conclusion: Ethnomedicinal antimalarial plants should not be combined without a data of previous scientific evaluations.

Fermentation properties and potential prebiotic activity of HCl-breadfruit resistant starch type III by Lactobacillus plantarum ATCC 13649 and L. brevis ATCC 8287

HCl-breadfruit resistant starch type III (HCl-BFRS3) is a type of resistant starch (RS) produced from breadfruit (Artocarpus altilis). Generally, RS is the non-digestible starch fraction that resists digestion in the gastrointestinal tract, and is completely or partially fermented in the colon which gives it beneficial physiological effects as a potential prebiotic. The present work assessed the fermentation properties of HCl-BFRS3 produced by local underutilised food crops. HCl-BFRS3 with 57.86% of RS content was analsyed for its fermentation properties. In vitro fermentability of HCl-BFRS3 with pure cultures of lactic acid bacteria, LAB (Lactobacillus plantarum ATCC 13649 and L. brevis ATCC 8287), was studied. Their growth patterns, pH changes, and prebiotic activity score (PAS) along with four other different carbohydrate sources (glucose, inulin, fibersol-2, and breadfruit starch) and a control sample against Escherichia coli ATCC 11775 was evaluated after 72 h of fermentation. It was found that HCl-BFRS3 selectively supported the growth of both lactobacilli and E. coli ATCC 11775, in the range of 6.21 to 9.20 log10 CFU/mL. HCl-BFRS3 also decreased the pH from the fermentation by L. plantarum ATCC 13649 and L. brevis ATCC 8287 after 24 h. The highest PAS was obtained by L. plantarum ATCC 13649 grown on HCl-BFRS3 (+1.69) as compared to inulin and fibersol-2. In conclusion, HCl-BFRS3 could be exploited as a prebiotic that benefits human health. Nevertheless, further assessment on the suitability of HCl-BFRS3 as a prebiotic material needs to be carried out.

Application of Irvingia gabonensis, Manihot esculenta and Artocarpus altilis as rheological modifier in water-based drilling fluid

The influence of natural polymers (cassava starch, breadfruit starch, bush mango seed and corn fibre) on the rheological properties of Uturu bentonite clay was investigated in this study towards developing a water-based drilling fluid. Before the fluid development, the additives were ball-milled to nano-sized particles for effective dispersion in the fluid. Individual effects of each additive on rheological properties (plastic viscosity (PV), apparent viscosity (AV), yield point (YP), consistency index (k) and flow index (n) of the formulated drilling fluid (DF) were initially evaluated using One-factor-at-time (OFAT) method to understand the heavy hitters. To gain insight to the interactive effects of these factors, a statistically designed experiment Central Composite Design (CCD) was used. Results from the experiments via CCD were analyzed and regression models were developed for each rheological property. The optimum rheological properties of the DF were 28.24 cp; 7.78 cp; 14.21 cp and 12.86 lb/100ft2, for µ600, PV, AV and YP, respectively. These properties indicate that the developed DF could be suitable for drilling in a typical oil well.

Resilience of breadfruit agro-ecosystems in Hawaiʻi during the COVID-19 pandemic

BackgroundThe COVID-19 pandemic is interrupting domestic and global food supply chains resulting in reduced access to healthy diverse diets. Hawaiʻi has been described as a model social-ecological system and it has been suggested that indigenous agro-ecosystems have the potential to be highly productive and resilient under changing land-use and climate change disturbance. However, little research has yet been conducted exploring the disruption and resilience of agro-ecosystems in Hawaiʻi caused by the COVID-19 pandemic. The breadfruit tree (Artocarpus altilis; Moraceae) is a signature, multi-purpose-tree of the complex perennial agro-ecosystems systems in Oceania.MethodsThis case study explores the ways in which the breadfruit agro-ecosystems of Hawaiʻi have shown resilience during the COVID-19 pandemic.ResultsOur study suggests that breadfruit has increased its value as a subsistence crop during the COVID-19 pandemic, even in a developed economy like Hawaiʻi, and that resilience of Hawaiian breadfruit agroe-cosystems during a crisis can be supported through cooperatives and food-hubs.

Fertility Levels of Soils under Selected Tree Vegetations for Efficient Agro-Forestry in Imo State, Nigeria

In many parts of Nigeria, large areas of lands are dominated by tree crop vegetations for timber production and for fruits with land users not knowing the fertility status of soils in these vegetations. Continual evaluation of soil properties of these tree vegetations has become pertinent for agricultural sustainability. This study therefore was carried out to evaluate the fertility levels of soils under selected tree vegetations at National Horticultural Research Institute Okigwe, Imo State, Nigeria. Five tree vegetations that were over 20 years of establishment were selected namely: oil bean (Pentaclethra macrophylla Benth), African breadfruit (Treculia africana), mango (Mangnifera indica), Ogbonu (Irvingia gabonensis) and orange (citrus spp). In each of these tree vegetations, four soil samples were collected at uniform depths (0 – 20, 20 – 40 and 40 – 60 cm) at different locations using soil auger. The samples were analyzed using standard laboratory procedures. Data collected were statistically analyzed using analysis of variance. Results obtained showed that despite the ages of these vegetations, the soils were acidic, low in macronutrient and basic cation concentrations when compared to FAO standard. The highest exchangeable bases and organic matter (1.78%) was recorded on bread fruit vegetation. Therefore, there is need to increase the fertility status of these soils in these tree crop vegetations by adopting measures that will boost organic matter content of the soil irrespective of the duration of the vegetation and this will help in agro forestry and alley cropping.

Physicochemical characterization and bioactive compounds in breadfruit (Artocarpus altilis) and its dried products.

Breadfruit (Artocarpus altilis) is described as an important food source in the diet of several countries, being considered as a valuable food with the potential to positively impact food security in the world. Breadfruit is a fruit of Asian origin with considerable economic and food importance for the region, due to its exceptional nutritional characteristics that bring benefits to the health to its consumers. However in Brazil, the fruit is little known and is underused. Only a very few scientific publications emphasizing the technological characteristics of breadfruit processing have been reported in the literature, which motivated the realization of the present research on its physicochemical characteristics. The fruits used were obtained from domestic orchards at the ripe and “green” ripening stages. The analyses performed were of pH, total soluble solids, total titratable acidity, water activity, ash content, lipids, protein, moisture and color (L*, a*, b*, C* and ºHue). Antioxidant activity through ABTS, DPPH and FRAP assays, and total phenolics and flavonoids compounds were determined. Descriptive data were analyzed by Analysis of Variance (ANOVA), Tukey mean test (p&lt;0.05). The results of the physicochemical analysis indicated that the drying to obtain breadfruit flour is a viable alternative, which provides a nutritional increase and a more attractive color to the product, minimizes post-harvest losses, in addition to being a technology with high potential for the availability of new food alternatives. Comparing the two extracts, the antioxidant activity was higher in the ethanol extracts of breadfruit flour. This result may be related to the maturation stage and the concentration of its components. For the phenolics and flavonoids bioactive compounds, there was a significant difference (p&lt;0.05), evidencing the aqueous extract, when compared to ethanolic extract.

ACTIVITY SCREENING AND STRUCTURE MODIFICATION OF ARTOCARPIN AGAINST ACE2 AND MAIN PROTEASE THROUGH IN SILICO METHOD

Objective: SARS-CoV-2 is a type of coronavirus that causes COVID-19 disease. Currently, the right and effective drug for the treatment of COVID-19 has not been found. Artocarpin in the breadfruit plant (Artocarpus altilis), which was tested, has been shown to have antiviral activity. However, artocarpin has a hydroxyl group that can undergo oxidation within a certain time, thereby reducing the stability of the compound and non-specific antiviral activity. Methods: In this study, the structural modification of artocarpin was carried out to obtain compounds with anticoronavirus activity with good physicochemical properties. This research was conducted in silico, including molecular docking simulation, bioavailability prediction, and preADMET. Results: The top 20 modified compounds were selected from each target's top 3 compounds, which had better bond energies compared to the positive control. These 3 compounds have the potential to inhibit ACE2 and Mpro receptors and 1 compound are better at inhibiting both. Conclusion: From the results of the research conducted, we conclude that the 3 best compounds can be potential candidates that can be developed as COVID-19 therapy.

Phytochemicals, pharmacological and ethnomedicinal studies of Artocarpus

This article aims to review the scientific data on phytochemical and pharmacological studies of Artocarpus collected from Malaysia as well as to highlight their usage as ethnomedicine worldwide. About 55 Artocarpus species are distributed worldwide and 32 of the Artocarpus species can be found in Malaysia. Artocarpus species are well known worldwide for their edible fruits such as Artocarpus heterophyllus (jackfruit), Artocarpus integer (chempedak), and Artocarpus communis (breadfruit). Aside from its edible fruits, the timber is valued for light constructions, crates, large canoes, and boats. The literature for this review was searched using the term ‘Artocarpus’, ‘Artocarpus Malaysia’, ‘Artocarpus extracts’, ‘Artocarpus traditional medicine’ and ‘Artocarpus ethnomedicine’ from published books and scientific journals via various engines such as The Web of Science, PubMed, Science Direct, Scopus, Research Gate, and Google Scholar. The references cited from the retrieved articles were also scanned and cross-checked. All published studies on phytochemical and pharmacological activities of Malaysia's Artocarpus species up to January 2021 were included in this review. Articles on phytochemical studies of Malaysia's Artocarpus revealed the isolation of flavonoids as the major constituents. Research on pharmacological activities of the isolated phytochemicals showed that these compounds exhibited significant disease-linked-enzyme (tyrosinase, cholinesterase, glucosidase) inhibitors as well as antioxidant, anti-inflammatory, antimicrobial, and cytotoxic activities. The ethnomedicinal data gathered are useful to understand and prioritize Artocarpus species that can contribute to potent phytochemicals and possibly new drug leads. This review also provides valuable information for the future development of isolated compounds from Artocarpus species.

Polyisoprenoid Compounds from Tropical Fruit Trees in Universitas Sumatera Utara Campus

Tropical trees are a source of secondary metabolite compounds that have various biological activities that can help human life both for industrial and pharmaceutical needs. One of the secondary metabolites is polyisoprenoid. This study aims to identify and analyze polyisoprenoid compounds quantitatively from tropical fruit trees at the Universitas Sumatera Utara. Nine samples of tropical fruit were obtained, namely: Psidium guajava, Tamarindus indica, Manilkara kauki, Morinda citrifolia, Mangifera indica, Artocarpus communis, Artocarpus heterophyllus, Gmelina arborea, and Syzygium aqueum. Each sample was extracted and isolated the polyisoprenoid alcohol, then analyzed using two-dimensional thin-layer chromatography. The polyisoprenoid in fruit samples found at the Universitas Sumatera Utara was a type II and III polyisoprenoid compound. The total lipid values ranged from 48.7 mg/g dw to 262.9 mg/g dw, polyisoprenoids ranged from 1.2 mg/g dw to 9.5 mg/g dw, and polyprenols ranged from 0.5 mg/g dw to 5.7 mg/g dw. Carbon chain length and dolichol polyprenol lengths of each fruit were collected (Psidium guajava L.) (C70 C80), (Tamarindus indica L.) (C80 C95), (Manilkara kauki L.) (C80 C95 and C70 C90), (Morinda citrifolia L.) (C75 C100), (Mangifera indica L.) (C80 C90 and C75 C90), (Artocarpus communis) (C75 C95), (Artocarpus heterophyllus) (C70 C75 and C70 C100), (Gmelina arborea Roxb.) (C90 C95), and (Syzygium aqueum) (C65 C90 and C75 C90).

South Pacific cultivars of breadfruit (Artocarpus altilis (Parkinson) Fosberg and A. mariannensis Trécul) and their hybrids (A. altilis × A. mariannensis) have unique dietary starch, protein and fiber

Breadfruit (Artocarpus altilis and A. altilis × A. mariannensis) is a sustainable and highly nutritious staple crop that has been granted “Generally Recognised as Safe” status by the FDA. There are more than 300 cultivars of breadfruit selected by Indigenous Peoples of the Pacific Islands. To date, specific starch characteristics of individual cultivars have not been investigated. We hypothesized that starch and fiber vary in type, yield, and quality across breadfruit cultivars. The starch yield, structure, swelling power, solubility, dietary fiber, and starch-bound protein of starch isolated from 16 breadfruit cultivars were analyzed. Starch granule size ranged from 2.04 μm to 17.66 μm with the starch structures of hybrid cultivars appearing uniquely membranous. Three cultivars, Yuley, Ulu fiti, and Ma’afala, had particularly distinguishing characteristics. Ma’afala had the highest protein content. Ulu fiti had the highest starch yield but the lowest swelling power and solubility. Yuley had the highest dietary fibre (total, soluble, insoluble), swelling power, and low starch-bound protein. This variability in characteristics suggests Yuley is an ideal cultivar for various starch applications in foods, pharmaceuticals, industrial chemicals, and other applications.
