The Complete Chloroplast Genome of Erythrina variegata L. (Papilionoideae, Fabaceae).

Erythrina variegata L. 1754, a thorny deciduous tree of Fabaceae, contains various chemical compounds such as alkaloids, flavonoids, and triterpenoids and exhibits anti-depressant, anti-inflammatory, and antidiabetic activities. However, genomic data of E. variegata are limited. In this study, the complete chloroplast genome of E. variegata was sequenced and characterized using Illumina sequencing platform. The chloroplast genome of E. variegata was 152,351 bp in length and consisted of a large single copy (82,907 bp), a small single copy (26,309 bp), and two inverted repeat regions (16,826 bp). There were 79 protein-coding genes, 30 transfer RNA genes, and four ribosomal RNA genes. Comparative analysis revealed high conservation of chloroplast genomes among Erythrina species regarding genome size, structure, and gene content. The phylogenetic study also indicated a close relationship between E. variagata and E. sanwicensis. This study provides initial plastome data for further genomic studies examining E. variegata and related species in Fabaceae.

Assessment of binding affinity of major bioactive compounds from Momordica charantia, Azadirachta indica, Nelumbo nucifera, Caesalpinia crista, Martynia annua and Erythrina variegate to COX-2 receptor: an in silico study

In traditional medicine, potential anti-inflammatory and pain-relieving activity of Momordica charantia, Azadirachta indica, Nelumbo nucifera, Caesalpinia crista, Martynia annua and Erythrina variegate has been emphasized. In this study, we explored binding affinity of 36 bioactive compounds from these plants to cyclooxygenase-2 (COX-2) receptor using docking method. Six compounds namely, beta carotene, lycopene, lutein, momordicoside, rutin and azadirachtin showed excellent binding affinities (−10.29, −10.22, −10.03, −7.9, −8.81 and −7.88 kcal/mol, respectively) and stable interactions with COX-2 (greater than those of aspirin and diclofenac) and they were chosen for the molecular dynamics (MD) assessments done throughout a 100-ns time period. Based on the computed RMSD, RMSF, Rg, SASA and PCA, all ligands were found to form stable and adequate interactions with COX-2 protein; these findings were comparable to those of aspirin and diclofenac, indicating the potential inhibitory properties of these ligands on COX-2 protein. In addition, the toxicity of compounds was evaluated using Pred-hERG, Pred-Skin and ProTox-II. Since COX-2 inhibitors have been reported to activate the Nrf2 pathway, it is hypothesized that they may confer other health-promoting effects through triggering Nrf2 signaling.

LOCAL ECOLOGICAL KNOWLEDGE ON LAND SNAIL DIVERSITY IN MOUNT BANAHAW, PHILIPPINES

Local ecological knowledge (LEK) is a community-based conservation effort that promotes sustainable management of natural resources. However, studies on LEK are very limited in the Philippines. To address this information gap, LEK on land snails in Mount Banahaw, Luzon Island, Philippines was investigated. Key informant interviews and focus group discussions were conducted in the four communities (Dolores, Lucban, Tayabas and Majayjay) along the slope of the mountain. A snail calendar was used as a tool for identifying the hunting season and practices of these communities on land snails. The results showed that the communities were knowledgeable on macro land snails (>5 mm shell size) such as the introduced species, Lissachatina fulica and the endemic and edible, Ryssota otaheitana, but were unaware of micro land snails ( 5 mm shell size). Locals also demonstrated an awareness of the snails’ ecosystem functions as a food source for other animals and agents of nutrient cycling. Additionally, sustainable hunting of R. otaheitana in communities was observed. Only adult R. otaheitana were harvested, leaving the juveniles to grow and reproduce. In Lucban, the people hunted while they were waiting for the harvest season of their crops. In Tayabas, the community observed that the snail was abundant during wet and moist soil conditions when leaf litter, its primary food, decomposed easily. In Majayjay, hunting was associated with the blooming of the flowering plant, Erythrina variegata. In Dolores, hunting was practiced after clearing farmland. This research underscores the importance of determining LEK in developing policies and regulations on sustainable utilization and conservation of land snails in a tropical forest setting.

Physiological Characters of Vanilla Plant (Vanilla planifolia Andrew) in Various Types of Shade Trees

Vanilla plants are CAM plants and are very sensitive to direct sunlight, so vanilla plants need shade plants to reduce the intensity of sunlight. Research on the physiological characteristics of vanilla plants on various types of shade trees was carried out to finding out the influence of types of shade trees on the physiological characteristics of vanilla plants. The research was conducted using a randomized completely block design with four groups. Planting was carried out using four types of shade plants, namely Gliricidia sepium, Syzygium aromaticums, Erythrina variegata and Leucaena leucocephala plants. To determine microclimate conditions, temperature, air humidity and sunlight intensity were observed three times a day (morning, afternoon and evening). Physiological observation parameters include content of chlorophyll A, chlorophyll B levels, total chlorophyll, proline, relative water content. The results of the research showed that temperature, air humidity and the intensity of sunlight received are different for each type of shade plant. Types of shade plants significantly influence content of chlorophyll A, chlorophyll B, total chlorophyll, proline and relative water content. The conclusion was the type of shade plant affects the microclimatic conditions of the vanilla plant, thereby influencing the physiological properties of the vanilla plant.

Effect of cropping systems, top feeds and planting geometry on growth, yield and economics of top feeds

The present study was conducted to find out the effect of cropping systems, top feeds and planting geometry on the growth, yield and economics of different top feeds. The experiment was laid out in a split-split plot design with 18 treatment combinations and three replications. The treatments consisted of two cropping systems (C1-sole crop of top feeds, C2-intercrop of bajra napier hybrid), three top feeds [(F1-agathi (Sesbania grandiflora), F2-erythrina (Erythrina indica), F3-drumstick (Moringa oleifera)] and three planting geometry (G1-2 m x 1 m, G2- 2 m x 0.5 m, G3-paired system). The data over three years revealed that intercropping top feeds with bajra napier hybrid at a paired system (C2F1G3) recorded the highest mean number of branches in all three years. However, intercropping agathi at 2 x 0.5 m (C2F1G2) recorded the highest mean leaf stem ratio (0.82). Pooled data over three years also revealed that intercropping agathi at 2 x 0.5 m geometry recorded the highest total green fodder yield (30.16 t ha-1), total dry fodder yield (7.55 t ha-1), gross return (Rs 201200 ha-1), net returns (Rs 139000 ha-1) and B:C ratio (3.25). Hence, among different tree grass combinations, growing agathi with bajra napier hybrid at 2 x 0.5 m geometry was found as most promising system for meeting the fodder requirements of Kerala.

EFFECT OF VARIOUS CHEMICAL TREATMENTS ON PHYSICOCHEMICAL AND THERMAL PROPERTIES OF ERYTHRINA VARIEGATA FIBERS: APPLICATION IN EPOXY COMPOSITES

Recently, there has been an increasing trend in utilizing lignocellulosic fiber reinforced composites in structural applications within the construction and automobile industries, replacing conventional materials based on metals and their derivatives. In the present study, Erythrina variegata fibers (EVFs) were subjected to a number of chemical treatments individually (alkalization, benzoyl peroxide, potassium permanganate, and stearic acid treatments). The effects of these chemical treatments on the EVFs were examined through chemical composition analysis, X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and thermogravimetric analysis (TGA). This comprehensive analysis aimed to assess the suitability of the chemically treated EVFs for use as reinforcement in thermoset polymer matrix composites. The alkali treated fibers (AEVFs) were found as optimum and were then used as reinforcement in epoxy adhesives. Different fiber loadings (0, 5, 10, 15, 20, and 25 wt%) were incorporated into the epoxy matrix to investigate their effects on the properties of the composites. Therefore, the tensile strength, flexural strength, impact strength, and thermal stability of the prepared composites were evaluated under controlled laboratory conditions. The findings collectively suggested that the epoxy composites reinforced with 20 wt% of AEVFs exhibited promising characteristics for lightweight structural applications.

Synergistic effects on properties of biofuel and biochar produced through co-feed pyrolysis of Erythrina indica and Azadirachta indica biomass

Co-feed pyrolysis is a thermochemical conversion process that entails the simultaneous or sequential decomposition of various feedstock in an oxygen-free environment, concurrently improving the quality of the end products. The technique is widely used to produce a range of valuable products, including biofuels, chemicals and biochar, capitalizing on the synergies between various feedstock. The current study focuses on the synergistic effects of co-feed pyrolysis of Erythrina indica (EI) and Azadirachta indica (AI) biomass at different co-feed ratios (EI:AI) of 1:4, 1:3, 1:2, 1:1, 2:1, 3:1 and 4:1 on weight basis. The reactions were carried out at a temperature of 600 °C under a pressure of 1 bar using nitrogen as inert atmosphere. The bio-oil yield produced through the co-feed pyrolysis reactions ranged from 29.51 to 32.40 % by weight, while the biochar and non-condensable gases yields ranged from 38.25 to 42.48 % and 26.90 to 30.73 % by weight, respectively. Positive synergistic effects of co-feed pyrolysis led to a notable enhancement in physicochemical properties of the fuel phase, especially by virtue of calorific value, density and presence of low mol. wt. components when compared to their individual counterparts. Specifically, the fuel phase obtained at 1:1 co-feed ratio exhibited the peak calorific value of 36.80 MJ/kg along with lowest density of 0.82 g/ml and pH of 3.58 which is the pinnacle accomplishment of this work; and comparable with commercial gasoline. Gas chromatography and mass spectroscopy of biofuels revealed alkanes, alkenes, alcohols, aromatics, esters, nitro compounds and organosilicons as their main compounds. Specific compounds, including cyclopentane, methyl-, 1-cyclohexyl-2-propen-1-ol and 1-pentene, 3-methyl, are the most significant compounds at co-feed ratio of 1:1. Biochar produced at co-feed ratio of 1:1 also depicted excellent physiochemical properties with the highest elemental carbon of 79.23 wt % and lowest oxygen and hydrogen contents of 18.49 wt % and 2.28 wt %, respectively with a maximum calorific value of 29.23 MJ/kg; which can be utilized as solid fuels. The biochar produced from the co-feed pyrolysis reactions also possesses highly porous structure which can be useful as a soil conditioner, carbon sequestration water filtration or wastewater treatment. Additionally, non-condensable gases composed of 7.45 vol % hydrogen, 34.26 vol % carbon monoxide, 21.32 vol % methane and 36.97 vol % carbon dioxide when co-feed ratio is 1:1.

The green-synthesized AgNPs underwent characterization using multiple analytical techniques, including UV–visible, FTIR, DLS, SEM, TEM, XRD, and EDX, and estimation of their antioxidant activity and antimicrobial activity. Phytochemical analysis identified alkaloids, tannins, saponins, flavonoids, and phenols as secondary metabolites. The Total Phenol Content (TPC) was determined to be 237.35 ± 2.02 mg GAE-1, indicating a substantial presence of phenolic compounds. The presence of AgNPs was verified through UV–Visible analysis at 420 nm, and FT-IR revealed characteristic phenolic functional groups. DLS analysis indicated a narrow size distribution (polydispersity index - PDI: 3.47%), with SEM revealing spherical AgNPs of approximately 20 nm. TEM showed homogeneous, highly polycrystalline AgNPs with lattice spacing at 0.297. XRD analysis demonstrated crystallinity and purity, with distinct reflection peaks corresponding to miller indices of JCPDS card no. 01 087 1473. In vitro, AgNPs exhibited robust antioxidant activity like; DPPH, ABTS, and H2O2, surpassing E. indica-assisted synthesis. ABTS assay indicated higher antioxidant activity (81.94 ± 0.05%) for AgNPs at 734 nm, while E. indica extraction showed 39.67 ± 0.07%. At 532 nm, both E. indica extraction (57.71 ± 0.11%) and AgNPs (37.41 ± 0.17%) exhibited H2O2 scavenging. Furthermore, AgNPs displayed significant antimicrobial properties, inhibiting Staphylococcus aureus (15.7 ± 0.12 mm) and Candida albicans (10.7 ± 0.17 mm) byfor the concentration of 80 μg/mL. Through the characterizations underscore of the potential of Erythrina indica-synthesized AgNPs, rich in polyphenolic compounds, for pharmacological, medical, biological applications and antipyretic properties.

Fictional faces of female suicide: Qualitative analysis of selected Russian-language texts of the school reader

IntroductionIsaiah Berlin’s (1948) exploration of the self-searching of Russian thinkers includes studies of the writers – Tolstoy and others (now – Russian-language texts of the school reader). These studies refute a widespread misconception about the relations between Russian writers and thinkers: namely, that in Russia literature and radical thought form two distinct traditions related only by mutual hostility. The works of Tolstoy, Dostoevsky, Karamzin, Leskov, Ostrovsky, and of minor novelists too, are penetrated with a sense of their own time, of this or that particular social and historical milieu and its ideological content, to an even higher degree than the ‘social’ novels of the west. The personal characteristics of suicide victims, heroines of Russian literature, along with the gender aspects, deserve attention in suicidal behavior (SP) focus.ObjectivesTo study personal characteristics of suicide victims, heroines of fiction.MethodsQualitative analysis of selected Russian-language texts of the school reader.ResultsAt the dawn of literature, we have seen fiery heroines and tremulous victims in the arms of death. Аs psychology approach was developed, and we get acquainted with the tragiс backstory. Psychotypes of suicides are exaggerated and overlapped. «Hysterical»: manipulative, frigid nymphomaniac (e.g., Anna Karenina). «Freedom-loving rebel» (i.e., Katerina reincarnations from A. Ostrovsky) in conditions of excessive regulation. «She-Devil, or Rebel Without a Cause». The obsession with death turns into a criminal and a victim (e.g., «Lady Macbeth of the Mtsensk» by N. Leskov, Turgenev’s Susanna or Klara Milich). The image of a vindictively furious («velvet and tiger claws») woman descends to the Victorian view of female self-will. «Mimosa» is a sensitive, dreamy person, unable to resist the hardships of life, dependent (dies with her beloved, objection). In suicide, the strength of weakness is the outcome of a humiliating life (e.g., Karamzin’s «Poor Liza», «A Gentle Creature» by F. Dostoevsky. The meaning of suicides is the following: a call (to compassion, salvation), a «cry for help», atonement for one’s (imaginary) – someone else’s (by proxy) guilt, and release from encumbrance.ConclusionsFiction and life are united by emotionally unstable characters and/or depression as markers of unsatisfactory resilience. The cultural diversity of gender patterns and interpretations of SP challenges the essentialist view that «femininity» and marriage are protective factors. SP patterns illustrate and complement the explanatory concepts of SP. The inner world of suicidal people is fascinating and contributes to the evidence-based optimism in the «patient-centric» crisis care model.Disclosure of InterestNone Declared

Synergistic effect of Erythrina variegata L. and tamoxifen against the growth of breast cancer cells

Breast cancer is the most common malignancy and the second leading cause of death in women. While tamoxifen (TAM) remains to be a first-line agent for prevention and treatment of estrogen-receptor (ER) positive breast tumors, TAM resistance represents one of the biggest clinical challenges in breast cancer therapy. Therefore, there has been growing interest in the identification of novel agents including those of plant origin that enhance the TAM sensitivity of breast cancer cells. In the present study, we aimed to evaluate the synergistic effect of Erythrina variegata extract (EVE) and TAM on the suppression of breast cancer cell growth using MCF-7 cell model and conventional bioassays such as MTT and colony formation assay, cell cycle analysis, and immunocytochemistry. Interestingly, MTT assay in combination with Chou-Talalay analysis demonstrated the potent synergism between EVE and tamoxifen against MCF-7 cell survival. Additionally, co-treatment of MCF-7 cells with EVE and TAM more significantly suppressed colony formation, cell cycle progression, and the nuclear expression of proliferative marker Ki67 compared to TAM alone. These findings imply that EVE potentiates the anti-proliferative effect of TAM in MCF-7 breast cancer cells and may become a promising agent in the treatment of ER positive breast cancer.

Potential protein tyrosine phosphatase 1B and α-glucosidase inhibitory flavonoids from Erythrina variegata: Experimental and computational results

Erythrina variegata L., a member of the Fabaceae family, is a valuable medicinal plant with a rich history of traditional medicinal uses. However, its potential as an antidiabetic agent has remained largely unexplored. In this study, three isoflavonoid compounds, namely eryvarin M (1), eryvarin H (2), and neobavaisoflavone (3), were isolated from E. variegata. These compounds displayed significant inhibitory effects on both protein tyrosine phosphatase 1B and α-glucosidase enzymes. The specific attachment position of the prenyl group to the isoflavonoid skeleton plays a pivotal role in determining the variation in their activity. Moreover, the results obtained from docking simulations corroborate the experimental findings, confirming the robust binding affinities of these metabolites toward the target proteins. The docking analysis further highlights that these compounds exhibit highly negative values of binding-free energies against proteins, indicative of their favorable binding affinities. In addition, the formation of hydrogen bonds in the binding region contributes to their binding interactions. These findings significantly enhance our understanding of the therapeutic potential of both E. variegata and its isoflavonoids as potential inhibitors for diabetes and related metabolic disorders, shedding light on their promising role in the field of diabetes research.

Extraction methods and plant species influences the anthocyanin and carotenoid content in the flowers of nine common landscape plants

Anthocyanin and carotenoids are the two major groups of plant pigments having beneficial effects on human body. Anthocyanin, a water-soluble coloured flavonoid that imparts red, blue and purple colour in fruit, vegetables and flowers possesses anti-carcinogenic and anti-inflammatory properties, preventive in cardiovascular diseases, obesity and diabetes, and improves visual and brain functions. Carotenoids, C40 isoprenoid compounds, impart yellow to orange red colours to flowers are antioxidants, anti carcinogenic, protect cornea against UV light, and reduces cholesterol levels. Flowers are prominent sources of these two bio-compounds. The present study aimed at extraction of anthocyanin and carotenoid from flowers of nine common landscape plants (Erythrina indica, Delonix regia, Spathodia campanulata, Casis fistula, Peltophorum pterocarpum, Cassia alata, Lagerstroemia sp., Clitoria sp. and Eicchornia crassipes) blooming in red, yellow and blue, through four aqueous extraction methods with varying temperature and microwave assistance. The results indicated that the anthocyanin and carotenoid content varied significantly among the flower species, methods of extraction and their interaction. Maximum anthocyanin content was obtained from blue-coloured flowers of Clitoria sp. (64.44 mg l-1) in microwave assisted extraction and maximum carotenoid content from red-coloured flowers of Delonix regia (99.60 µg g-1) in cold water maceration.

ISOLATION AND INHIBITION STUDY OF ERYVARIN D AND E FROM THE ROOT BARKS OF Erythrina variegata AGAINST RECEPTOR TYROSINE KINASES

Erythrina sp. contains alkaloids and flavonoids, which are the primary bioactive compounds found in these species. These organisms are a rich source of secondary metabolites. Two known pterocapans in this study, eryvarin D (1) and eryvarin E (2), were successfully isolated from the root bark extract of Erythrina variegata. The isolated compounds were elucidated using 1D- and 2D-NMR spectroscopy. Among the two compounds, only compound 2 was evaluated for its inhibitory activity against eight receptor tyrosine kinases (EGFR, HER2, HER4, IGFR, InsR, KDR, PDGFRα, and PDGFRβ). Compound 2 exhibited weak insulin receptor inhibitory activity. Thus, compound 2 could be a lead compound as an anticancer drug targeting insulin receptors for future development.

Molecular Docking Studies of selected Erythrina variegata Leaves Alkaloids towards Estrogen Receptor (1A52 and 1GWR) and their Binding Interaction Analysis

Medicinal plants possess many phytochemicals of great therapeutic value and many of them are effective in killing cancer cells. These compounds working by variety of mechanisms and in most of the cases they exhibit their anticancer potentiality by inhibiting many proteins involved in cell growth and division. Molecular docking is a computational approach which facilitates the finding of the best molecule from a group which may bind with the highest affinity with the intended target by providing a virtual biological system. This process works on the basis of specific algorithm and involves scoring function to rank the molecules that fit with the target. The present study has been designed to investigate the potentiality of eight alkaloids compounds from leaves of Erythrina variegata natural products and two anticancer drugs have selected and docked against Estrogen receptor proteins (PDB ID:1A52 and 1GWR) to treat cancer cells. Among them 6-hydroxy genistein ranks first with very good binding with the very good dock score with these receptors and has the potential to treat the cancer cells against the Estrogen receptor proteins 1A52 and 1GWR.

Enhanced visible light-driven photocatalytic activity of green synthesized cobalt ferrite nanoparticles

Cobalt ferrite nanoparticles were synthesized through green synthesis using Erythrina variegata leaf extract. The presence of phytonutrients in the Erythrina variegata leaf extract was confirmed by phytonutrient screening analysis. The thermal, structural, optical, functional, chemical, morphological, and compositional properties of prepared nanoparticles were analysed. The crystal violet (CV) and congo red (CR) dyes eliminated from water using CoFe2O4 NPs as an adsorbent, has been reported. The thermal stability of as-prepared samples was studied by TG-DTA and powder XRD analysis exhibits a cubic inverse spinel structure. By using UV–Vis spectroscopy, the lower band gap energy of CoFe2O4 NPs was found to be around 1.86 eV. The relevant FTIR and Raman spectra indicated Fe–O (tetrahedral site) and Co–O (Octahedral site) band, which attributed to the stretching vibration modes. The cubic-shaped and irregular agglomerated particles was examined from SEM images. The existence of all required elements in prepared CoFe2O4 NPs were confirmed by EDX and XPS analysis. Leaching experiment using the seed germination method for CoFe2O4 catalyst was evaluated. Moreover, the effective photocatalytic performance of crystal violet (CV) and congo red (CR) dye adsorption using CoFe2O4 catalyst within 120 min on the effect of pH, dye dosage, exposure time, and kinetic studies under visible light were investigated. The maximum dye removal efficiency of 85.18 % and 79.58 % was observed using 25 mg/L at pH 9 for CV and CR dyes, respectively. Trapping experiments revealed that O2•− is the major active species in the dye degradation. Recycling experiments revealed good stability after three cycles for CoFe2O4 catalyst. As a result, the prepared CoFe2O4 NPs can be utilized as an effective adsorbent for wastewater treatment.
