“…In the extract from A. muricata , all tested phytochemicals were present, except for reducing sugar, phlobatannins, and glycosides ( Table 1 ). This finding contrasts with the results reported by Naik and Sellappan ( 2019 ), who observed the absence of phenolics and flavonoids in the root, leaf, bark, and rind of A. muricata extracted with ether by maceration. Algandaby ( 2015 ) and Azwinda ( 2015 ) highlighted that the presence or absence of phytochemicals depends on various factors, including the test method, solvent, particle size, moisture content, solvent-to-sample ratio, pH, temperature, length of extraction, extraction method, plant part, and origin/environment.…”

With the advent of modern technology, advancements in processing and storage techniques, and increasing medical knowledge, people are becoming aware of deterioration in the quality of medicinal products due to storage methods and time. In most cases, herbal products are not consumed immediately after production; as such, improper storage can result in physical, chemical, and microbiological changes. The study evaluated the effect of storage methods and time on the quality of oil extracted from Phyllanthus amarus Schumach and Annona muricata Linn and assessed their antidiabetic and antioxidative effects. Plants were air-dried, pulverized, and then subjected to Soxhlet extraction in petroleum ether. The oil was evaluated for phytochemical constituents and the effects of time and storage methods on its physicochemical properties. Characterization of the oil was done by spectroscopic techniques. Oils from both plants contained tannins, flavonoids, alkaloids, steroids, glycosides, terpenoids, phlobotannins, resins, reducing sugar, phenols, and saponins in different proportions. The oil from A. muricata had higher phenolic (3.11 ± 0.31 mg GAE/g), flavonoid (11.82 ± 0.08 mg QUE/g), alkaloid (16.37 ± 0.56 mg APE/g), and tannin (7.13 ± 0.47 mg CE/g) contents than the oil from P. amarus , which had 0.54 ± 0.08 mg GAE/g, 7.83 ± 0.13 mg QUE/g, 9.87 ± 0.15 mg APE, and 3.16 ± 0.12 mg CE/g for total phenolic, flavonoids, alkaloids, and tannins, respectively. Initial acid, iodine, peroxide, and saponification values recorded for P. amarus were 5.63 ± 0.82 mg KOH/g, 97.17 ±0.53 Wijis, 9.31 ± 0.15 mEq/kg, and 116.11 ± 0.74 mg KOH/g, respectively, significantly different from those of A. muricata , which had values of 1.17 ± 0.08 mg KOH, 76.23 ± 0.03 Wijis, 6.75 ± 0.47 mEq/kg, and 193.31 ± 0.52 mg KOH/g, respectively. FT-IR characterization of the oils revealed the presence of carboxylic acid, alkyl, alkene, alkane, haloalkane, aldehyde, aromatic amine, α-unsaturated and β-unsaturated esters, and phenol functional groups. P. amarus oil inhibited α-amylase (IC 50 0.17 ± 0.03 mg/ml), α-glucosidase (IC 50 0.64 ± 0.03 mg/ml), and xanthine oxidase (0.70 ± 0.01 mg/ml) to a greater extent than A. muricata oil, with IC 50 values of 0.43 ± 0.05 mg/ml (α-amylase), 2.25 ± 0.31 mg/ml (α-glucosidase), and 0.78 ± 0.07 mg/ml (xanthine oxidase). This study showed that oils from the tested plants have low rancidity with a moderate shelf life. The extracts contained essential phytoconstituents that significantly inhibited α-glucosidase and xanthine oxidase. These effects of the oil indicate their potential to prevent diabetes, gout, and oxidative stress. Consequently, the supply of P. amarus and A. muricata in homemade diets is strongly encouraged fo...

“…The results of the screening carried out showed the presence of several classes of compounds that are natural bioactive substances such as essential oils, coumarins, sterols, saponins, sugars, terpenes and flavonoids. Several of these compounds have also been obtained by Omolara et al [48]; Naik and Sellappan [49] with Annona muricata.…”

Background: Cercospora leaf spot disease of okra whose pathogen is Cercospora malayensis causes yield losses of up to 60% in plantations. To limit productivity losses, fungicides are commonly used, but are expensive and degrade the environment. Aims: This study aims to test in vitro efficacy of Annona muricata seed extracts against Cercospora malayensis. Study Design: Four extracts were used in this study (the ethyl acetate, acetone, methanol and aqueous extract of A. muricata seeds at the concentrations C1 = 7.5 μl/ml, C2 = 15 μl/ml, C3 = 30 μl/ml and C4 = 60 μl/ml as well as the synthetic fungicide at the concentration of 3.33 g/l) in triplicate. The phytochemical screening of the extracts was performed, the radial growth of pure explants (7 mm diameter) of C. malayensis deposited in sterile Petri dishes containing the PDA medium supplemented with the different concentrations of extracts and incubated at 23 ± 1°C for 6 days were evaluated. Minimum inhibitory concentrations (MIC50, MIC90) were calculated. Results: The extracts of A. muricata seeds are rich in tannins, flavonoids, terpenoids and phenols. The ethyl acetate extract at the concentration C3 resulted in 100% total inhibition of growth of C. malayensis in the Petri dishes. The other extracts resulted in total inhibition of the growth of C. malayensis at C4. The low MIC50 values (12.9 and 21 μl/ml) were obtained with the ethyl acetate and acetone extract, respectively. The ethyl acetate and aqueous extract at the C4 concentration were found to be fungicidal. Conclusion: The extracts were found to be potential fungicide against the C. malayensis strain and might be an alternative in the fight against fungal diseases of okra as their activity was comparable to that of the synthetic fungicide Monchamp 72 WP.

“…Some chemical constituents have the ability to recognize sites of action in the pathogen, others do not. They would thus act through a concentration effect and once fixed on their receptors, would elicit responses such as inhibition of general metabolism (fungistatic effect) or alteration of the plasma membrane of the fungus and inhibition of respiration (fungicidal effect) [49,50,51]. Callomil Plus 72 WP was very effective against P. colocassiae at all doses with inhibition percentages of around 100% on strain growth.…”

Aims: This study was aimed to evaluate the antifungal activities of acetone and ethyl acetate extracts of Thevetia peruviana seeds on the in vitro growth of the fungus. Study Design: A randomized sample block design containing four treatments (T- = Negative control; T2= Ethyl acetate extract; T3= Acetone extract; T+=Callomil Plus) with three repetitions was used. Plant extracts were used at three concentrations: C1: 12.5 µl/ml; C2: 25 µl/ml and C3: 50 µl/ml; the chemical fungicide at the dose of 12.5 μL/ml. Place and Duration of Study: The study was conducted in the University of Yaoundé 1, Faculty of Sciences, Department of Plant Biology, Laboratory of Phytopathology and Crop Protection, and in the Institute of Agricultural Research for Development (IARD) of Yaoundé, Laboratory of Phytopathology, during the year 2019-2020. Methodology: acetone and ethyl acetate extracts of T. peruviana were prepared and used at concentrations of 12.5, 25 and 50 µl/ml. P. colocasiae was isolated from infected taro leaf cultivars "Macumba or Ibo coco" located in three different regions: west, Littoral and Centre. The various explants were were put in V8 agar medium and maintained in pure culture. Mycelial fragments of P. colocasiae of about 0.8 cm in diameter were cut and placed in sterile Petri dishes containing Potato Dextrose Agar (PDA) medium supplemented with different concentrations of plant extracts and incubated at 23±1°C for seven days for the evaluation of the radial growth. Results: The results obtained showed that the acetone and ethyl acetate extracts have completely inhibited the growth of the strain of West at 25 μ/ml while total inhibition of the pathogen was not obtained with strain of Centre region. The lowest inhibition was obtained with the strain of Littoral region: 93.88 % for acetone extract and 90.78 % for ethyl acetate extract compare to 100 % for west and Centre region at highest concentration. Conclusion: The acetone and ethyl acetate extracts at the concentration of 25 μ/ml totally inhibited the in vitro radial growth of some strains of P. colocasiae. These extracts, which are effective against P. colocasiae, may substitute fungicides in the fight against taro leaf blight.
