KEYWORDS: Secondary metabolites, Medicinal plants, Qualitative analysis

INTRODUCTION Medicinal Plants and secondary metabolites A Medicinal Plant is any plant which, in one or more of its organs, contains substances that can be used for therapeutic purposes or which are precursors for the synthesis of useful drugs. The term “Medicinal Plants” includes various types of plants used in herbalism. According to WHO, around 21,000 plant species have the potential for being used as medicinal plant. More than 30% of the entire plant species, at one time or other were used for medicinal purposes.

MATERIALS AND METHODS: The present research work was undertaken with the aim of qualitative analysis of secondary metabolites for 25 plant samples using aqueous and alcoholic extractions, and establishing tissue culture in five selected plant species among the 25 species. The experiments of the present studies were carried out at the plant biotechnology laboratory at S. Thangapazham Agricultural College, Vasudevanallur. Details of materials and methods used were as follows.

Plant samples: Totally 25 plant samples were selected from mini-orchard medicinal garden, some from Nursery garden and some of the weeds from fields of S.Thangapazham Agricultural College Campus.

Aqueous extraction of plant sample: Weight of fresh leaves were taken and washed thoroughly and left for drying. Later after complete drying. Dried samples were completely dried in incubator at 60˚c for 8 hours and then the dried leaves were made into fine powder in mechanical grinder, powdered leaf sample of plant taken into a butter paper cover (Kumari and Bhatnagar 2016). And some modification are done from the known procedure after several trials, For 5g of sample 50ml of distilled water added in the ratio of 1:10.Boil it under 600 c for 30 minutes for secondary metabolite content in the leaf powder dissolve into the aqueous, then filtrate through whattman no.1 filter paper to getting clear extract. After filtering, the extracts were centrifuge at 2500 rpm for 15 minutes and store it in sterile bottle at 50 c for further use. Ethanolic extraction of plant sample: 250 g of fresh leaves were taken washed thoroughly and transferred into a round bottomed flask and it was added 500ml of ethanol and 500 ml of distilled water and was preserved carefully until 10 days, the extraction was taken and was filtered using whattman filter paper and feature pure sample was obtained using the Soxhlet apparatus (Das 2016). And modification taken are, For 10g of air dried powder macerated with 100 ml of ethanol, kept in the shaker for 72 hours, then kept at reduced pressure concentrated to 100 ml, Redissolve with alcohol and store it for further use.

Qualitative analysis of secondary metabolites: Alkaloids (Stochmal et al., 2022): 1ml of 1% HCl was added to 3 ml of extract in a test tube and was treated with few drops of Meyer’s reagent. If the creamy white precipitation occur which indicate the presence of alkaloid. (Mayer’s reagent: Freshly prepared by dissolving a mixture of mercuric chloride (1.36 g) and of potassium iodide (5.00 g) in water (100.0 ml).

Saponins (Kumari and Bhatnagar 2016): 5 ml of extract was shaken vigorously to obtain a stable persistent froth. The frothing was then mixed with 3 drops of olive oil and formation of emulsion which indicated the presence of saponins.

Tropoflavin, also known as 7,8-dihydroxyflavone, is a naturally occurring flavone found in Godmania aesculifolia, Tridax procumbens, and primula tree leaves.[2][3][4] It has been found to act as a potent and selective small-molecule agonist of the tropomyosin receptor kinase B (TrkB) (Kd ≈ 320 nM), the main signaling receptor of the neurotrophin brain-derived neurotrophic factor (BDNF).[5][6][7] Tropoflavin is both orally bioavailable and able to penetrate the blood–brain barrier.[8][9] A prodrug of tropoflavin with greatly improved potency and pharmacokinetics, R13 (and, formerly, R7), is under development for the treatment of Alzheimer's disease.[10][11] Tropoflavin has demonstrated therapeutic efficacy in animal models of a variety of central nervous system disorders,[7] including depression,[8] Alzheimer's disease,[12][13][14] cognitive deficits in schizophrenia,[15] Parkinson's disease,[5] Huntington's disease,[16] amyotrophic lateral sclerosis,[17] traumatic brain injury,[18] cerebral ischemia,[19][20] fragile X syndrome,[21] and Rett syndrome.[22] Tropoflavin also shows efficacy in animal models of age-associated cognitive impairment[23] and enhances memory consolidation and emotional learning in healthy rodents.[24][25] In addition, tropoflavin possesses powerful antioxidant activity independent of its actions on the TrkB receptor,[26] and protects against glutamate-induced excitotoxicity,[27] 6-hydroxydopamine-induced dopaminergic neurotoxicity,[28] and oxidative stress-induced genotoxicity.[29] It was also found to block methamphetamine-induced dopaminergic neurotoxicity, an effect which, in contrast to the preceding, was found to be TrkB-dependent.

A Brief Romp in Isca's Backyard

(date: 6th March, 2024)

we're past the worst of Tropical Cyclone Season, which reminded me that perhaps the local butterflies would come back -- here's what i've found this week!

note: all photos were taken on my Samsung Galaxy A30.

firstly, this tiny (approx. 4mm) little guy in its early instar! It's definitely a member of Papilionidae, though I'm not fully sure that it's an orchard swallowtail (P. aegeus), because its colouration is a little different from other early instars I've seen so far. either way, i'm keen to watch how it develops!

this bigger lad (left) is a P. aegeus, but this one's in its late instar! sometime soon it should turn into a pupa, just like its companion (right) hanging out on another branch!

while I was outside, I spotted this poor orange just split open. perhaps someone or something couldn't wait for it to ripen up first. it's not a big deal, though -- our orange tree is ridiculously prolific.

while I was outside the other day, we found a small litter of eastern red lacewings (Cethosia cydippe) on some passionfruit vine growing under the orange tree. I didn't have my phone on me then, and when I went looking for them today, I couldn't find them as mum had pulled out the vine. so instead, I opted to do a drawing of one. (note: artist's impression was drawn in Clip Studio Paint.)

I also spotted these two beetles. I don't actually know what the one on the left is -- but the one on the right is definitely an Asian Ladybeetle (Harmonia axyridis). they were both sitting on different parts of the same tridax daisy (Tridax procumbens), which is one of the many invasive plants in my area (and in our backyard).

Green Synthesis of Fe3O4 Nanoparticles from Alternanthera Philoxeroides

Abstract

Iron oxide nanoparticles, notably magnetite (Fe3O4), have become widely used and a key topic of research due to their superparamagnetism and distinctive features. As a result, scientists are diligently looking into new uses for these nanoparticles. The choice and use of synthesis techniques are important variables that might affect the size and characteristics of the nanoparticles (NPs). The use of harmful compounds that are absorbed on the surface of the nanoparticles has been linked to a number of negative impacts of chemical production processes. The Green synthesis of nanoparticles has evolved as an eco-friendly method in response to environmental concerns, giving researchers the chance to internationally investigate the potential of various herbs for nanoparticle synthesis. The aqueous extract of Alternanthera Philoxeroides leaves and the precursors ferric chloride anhydrous (FeCl3 anhydrous) and ferrous chloride tetrahydrate (FeCl2.4H2O) are used in this study to demonstrate a green synthesis approach for manufacturing magnetite nanoparticles. Thermogravimetric analysis (TGA), Fourier transform infrared spectroscopy (FTIR), vibrating-sample magnetometer (VSM), and UV-visible spectroscopy were used to evaluate the produced FeNPs. The presence of functional groups including (-OH), (C-H), and (-NH) was detected in the FTIR findings, showing that organic compounds had been coated on the FeNPs. A maximum absorption peak was detected in the ultraviolet-visible spectra of the aqueous media containing iron nanoparticles at about 330 nm. The magnetic characteristics of the produced FeNPs were verified by VSM testing. Numerous uses for these nanoparticles exist, such as waste water treatment, energy production, and others.

Introduction

Nanoparticles have seen an increase in demand in recent years, due to their use in various fields, including health, catalysis, energy, and drug delivery systems (Nam et al., 2009; Li et al., 2011). The physical, chemical, optical, and electrical properties of these nanomaterials are significantly influenced by the size, shape, and surface morphology of the nanoparticles. Various techniques, including physical vapor deposition, chemical vapor deposition, the solgel method, co-precipitation method, ultrasonic method, electrochemical synthesis, and chemical reduction of metallic ions, are used to create metallic nanoparticles (Horwat et al., 2011; Sobhani et al., 2011; Starowicz et al., 2006). These Syntheses frequently involve toxic, expensive, and unsustainable substances. Due to the simplicity of synthesis, environmental friendliness, and increased stability of nanoparticles, green synthesis approaches based on fungus, microbes, plant and peel extracts are currently being investigated (Balaji et al., 2009; Kumar et al., 2011; Sukirtha et al., 2012). 

Because of their high saturation magnetization, Fe3O4 MNPs are simple to magnetically separate in an external magnetic field (Mohamed et al., 2017). Several studies have been done on the synthesis of MNPs using a variety of reducing agents, including hydrazine (Hou et al., 2005). Dimethyl formamide (Jian et al., 2006). Sodium borohydride (Cain et al., 1996). Carbon monoxide (Mondal et al., 2004) and others. The biocompatibility of MNPs is hampered by these highly reactive reducing agents, which also have negative environmental impacts. As a result, there are only a few bio-medical uses for chemically reduced MNPs. MNPs must be strictly biocompatible in order to be used in biomedical applications. Several research using plant extracts to synthesize Fe3O4-NPs have been successful. For instance, Artemisia annua fruit extract (Basavegowda et al., 2014). Perilla frutescens leaf extract (Basavegowda et al., 2014). Tridax procumbens (Senthil et al., 2012). Caricaya papaya extract (Latha et al., 2014). Plantain peel extract (Venkateswarlu et al., 2013). Grape proanthocyanidin seed extract (Narayanan et al., 2012). In the leaf extract, there are a number of polyphenols and acidic compounds available. These Polyphenols from the extract form complexes with metal ions and show both reducing and capping behavior for NPs Senthil et al., 2012. Also, these polyphenolic compounds are biodegradable, nontoxic, and water-soluble at room temperature, which proves that green leaf extract as an effective reducing agent compared to others (Latha et al., 2014). According to the literature analysis, no specific studies have been conducted on the synthesis of Fe3O4-NPs using the alligator weed Alternanthera Philoxeroides, which encourages and pushes us to work on this. We have developed a modified green synthesis method to prepare Fe3O4-NPs using green Alternanthera Philoxeroides extract as a reducing agent, a novel environmentally friendly technique for producing Fe3O4-NPs is suggested in this study.
