Comparative metabolites profiling of different solvent extracts of Asparagus species cladodes using liquid chromatography-mass spectrometry-based metabolomics and molecular networking.

Asparagus species are naturally distributed worldwide and are known for their pharmacological properties that offer cures for various ailments. However, the metabolic choreography of these Asparagus species is not well characterized, and the compounds contributing to their bioactivities remain unknown. This study aimed to profile and compare the metabolomes of three Asparagus species cladodes using different solvent extractions. An ultra-high performance liquid chromatography-quadrupole time-of-flight mass spectrometry-based metabolomics and molecular networking approach was used to study the effects of different solvents (ethyl acetate, methanol, and chloroform) with varying polarity on metabolites extraction and identification of bioactive compounds from three Asparagus species cladodes (Asparagus falcatus, Asparagus plumosus, and Asparagus densiflorus 'Meyersii'). Multivariate statistical analyses (mainly principal component analysis) revealed a significant separation between the three solvents and the three species, indicating notable metabolic differences. A total of 118 metabolites were identified in the three species extracted with the different solvents, with methanolic and chloroform extracts containing more metabolites compared with ethyl acetate extracts. These metabolites were identified as belonging to the flavonoids, cinnamic acids, organooxygen compounds, steroids, fatty acids, benzenes, and glycerophospholipids compound classes. Furthermore, these compounds classes were differentially distributed among the three species, indicating chemical/chemotaxis differences between the compared species. Chloroform and methanol are recommended as the optimal solvents to obtain a high content of phytochemical compounds from Asparagus species cladodes.

Larvicidal potential of Trachyspermum ammi essential oil and Delphinium speciosum extract against malaria, dengue, and filariasis mosquito vectors

Mosquito-borne diseases, such as malaria, dengue, and Zika, pose major public health challenges globally, affecting millions of people. The growing resistance of mosquito populations to synthetic insecticides underscores the critical need for effective and environmentally friendly larvicides. Although chemical pesticides can initially be effective, they often lead to negative environmental consequences and health hazards for non-target species, including humans. This study aimed to evaluate the larvicidal effects of Trachyspermum ammi essential oil and Delphinium speciosum extract on the larvae of three major mosquito species: Aedes aegypti, Anopheles stephensi, and Culex quinquefasciatus. Mosquito larvae of Ae. aegypti, An. stephensi, and Cx. quinquefasciatus were reared under controlled laboratory conditions. The larvicidal activity of T. ammi essential oil and D. speciosum extract was evaluated through standard bioassays, using various concentrations of essential oils (10, 20, 40, 80, and 160 ppm) and extracts (160, 320, 640, 1280, and 2560 ppm) to determine the lethal concentration (LC50) values after 24 h of exposure. Fresh plant materials were collected, with the essential oil extracted via hydro-distillation, and the extract prepared using methanol solvent extraction. The chemical composition of T. ammi essential oil was examined using gas chromatography-mass spectrometry (GC-MS). Additionally, the preliminary analysis of the chemical compounds in D. speciosum extract was carried out using thin layer chromatography (TLC) and nuclear magnetic resonance spectroscopy (NMR) techniques. The results indicated that the essential oil of T. ammi exhibited more effective larvicidal activity compared to the D. speciosum extract. Specifically, the essential oil demonstrated LC50 values of 18 ppm for Cx. quinquefasciatus and 19 ppm for Ae. aegypti. In contrast, the D. speciosum extract showed the strongest larvicidal effect against An. stephensi, with an LC50 of 517 ppm. Concentrations of 40 ppm of the essential oil and 1280 ppm of the extract resulted in 100% mortality across all three species. Both the essential oil of T. ammi and the D. speciosum extract exhibited concentration-dependent larvicidal activity, and these results were statistically significant (p < 0.001) compared to the no-treatment group. GC-MS analysis revealed thymol (88.95%), o-cymen-5-ol (4.11%), and γ-terpinene (2.10%) as the major constituents of the T. ammi essential oil. Additionally, TLC verified the presence of alkaloids in both chloroform and methanolic extracts. Proton NMR identified a diterpene structure for these alkaloids. These findings suggest that T. ammi essential oil is a promising candidate for natural mosquito control strategies. Given its efficacy, further research is warranted to explore its potential in integrated vector management programs.

Averrhoa carambola Leaf Extract Induces Apoptosis-Like Death with Increased ROS Generation in Leishmania donovani.

The parasitic disease leishmaniasis is responsible for high mortality and morbidity rates worldwide. The visceral form is the most severe form of leishmaniasis (or leishmaniosis), which is caused predominantly by Leishmania donovani. Currently, clinically recommended antileishmanial drugs are not convenient because of several medical complications and resistance issues. Phytocompounds are the best candidates in this regard. The present study aimed to evaluate the antileishmanial activity of Averrhoa carambola leaf extract. The antipromastigote activity and cytotoxicity were assessed using the MTT assay. Morphological distortions were determined using phase contrast microscopy and scanning electron microscopy (SEM). Reactive oxygen species (ROS) production, nonprotein thiol depletion and apoptotic death in promastigotes were determined via flow cytometry. UV-visible spectroscopy and energy dispersive X-ray (EDX) spectroscopy was performed for elemental analysis. Fourier-transform infrared spectroscopy (FTIR) and liquid chromatography‒mass spectrometry (LCMS) were used to characterize the phytocomponent(s) present in the extract. The chloroform extract of Averrhoa carambola leaf (ACCEX) (IC50 = 50.76 ± 1.7µg/mL) exhibited the highest activity, followed by the ethyl acetate, hexane, and methanol extracts. ACCEX has also exhibited lower toxicity towards host macrophages. ACCEX also induced morphological distortions in promastigotes, with significant generation of ROS and the concomitant apoptosis initiation followed by a decrease in the nonprotein thiol level. The major phytometabolites present in ACCEX were identified from the National Institute of Standards and Technology (NIST) database and from a literature review. This study suggested that Averrhoa carambola leaf extracts are rich in some classes of biologically active phytocompounds and exhibit good antileishmanial activity.

Experimental and computational insights of Albizia amara phytoconstituents targeting anthranilate phosphoribosyltransferase from Malassezia globosa

The fungus Malassezia globosa is often responsible for superficial mycoses posing significant treatment challenges because of the unfavourable side effects of available antifungal drugs. To reduce potential hazards to the host and overcome these hurdles, new therapeutic medicines must be developed that selectively target enzymes unique to the pathogen. This study focuses on the enzyme anthranilate phosphoribosyltransferase (AnPRT), which is vital to M. globosa's tryptophan production pathway. To learn more about the function of the AnPRT enzyme, we modeled, validated, and simulated its structure. Moreover, many bioactive components were found in different extracts from the plant Albizia amara after phytochemical screening. Interestingly, at doses ranging from 500 to 2000 µg/ml, the chloroform extract showed significant antifungal activity, with inhibition zones measured between 11.0 ± 0.0 and 25.6 ± 0.6 mm. According to molecular docking analyses, the compounds from the active extract, particularly 2-tert-Butyl-4-isopropyl-5-methylphenol, interacted with the AnPRT enzyme's critical residues, ARG 205 and PHE 214, with an effective binding energy of -4.9 kcal/mol. The extract's revealed component satisfies the requirements for drug-likeness and shows promise as a strong antifungal agent against infections caused by M. globosa. These findings imply that using plant-derived chemicals to target the AnPRT enzyme is a viable path for the creation of innovative antifungal treatments.

Effects of solvent extraction on the phytoconstituents and in vitro antioxidant activity properties of leaf extracts of the two selected medicinal plants from Malawi

This study evaluated and compared the phytochemical and antioxidant properties of the solvent extracts of Azadirachta indica A. Juss and Vernonia amygdalina Del leaves. Methanolic and aqueous extracts showed high (P ≤ 0.05) extract yields (in %), compared to chloroform and ethyl acetate extracts from both V. amygdalina and A. indica leaves. The study exhibited high phytochemical content in methanol and aqueous extracts compared to chloroform and ethyl acetate extracts, confirming the potential for medicinal use. V. amygdalina methanol and aqueous extracts had higher (P ≤ 0.05) total phenolic content (TPC), in mg GAE/gDW, (158.810±0.846 and 217.883±0.265, respectively) than chloroform (37.574±0.118) and ethyl acetate (104.758±0.236) but higher ethyl acetate content in A. indica extracts. Low polar solvents extracted high (P ≤ 0.05) total flavonoids, in mgQE/gDW, (367.051±0.858 and 149.808±0.009) compared to high polar solvents (14.863±0.071 and 54.226±0.014 ) in V. amygdalina while as in A. indica leaf extracts, low polar solvents showed high TFC ( 658.469±3.451 and 275.288±10.490) compared to high polar solvents (26.312±0.063 and 48.858±0.063) respectively. In vitro total antioxidant capacity, in mg/g, was higher in polar solvents than in low-polar solvents, ranging from 34.300±1.784 to 121.015±6.839 for A. indica ethyl acetate and methanolic extracts. A strong correlation between TPC and tannic acid content was observed, except in A. indica methanolic extracts of A. indica. Ferric reducing power was high, except for V. amygdalina chloroform and methanol leaf extracts, which were lower (P≤ 0.05) than that of the standard ascorbic acid. The study revealed that high polar solvents, such as methanol and water, are more efficient in the extraction of antioxidants from A. indica but lower in V. amygdalina extracts. High phytochemical content and antioxidative capacity could be significant in treating various diseases in humans.

In Vitro Antifungal Efficacy of Allium Cepa And Allium Sativum: A Comparative Study with Commercial Drugs

The in vitro activities of water, methanol, acetone, ethanol, and chloroform extracts of garlic (Allium sativum) and Onions (Allium cepa) were investigated. For comparison, activities of commercially sold antifungals viz Nystatin, Fulcin, and Cotrimoxazole against Aspergillus niger, Aspergillus fumigatus, Aspergillus flavus, Penicillium spp, Trichophyton schoeleinii, and Neurospora clasa were also investigated. The largest zone of inhibition was exerted by the ethanol and water extracts of garlic (Allium sativum) against Aspergillus niger, A. fumigatus, T. Schoeleilnii, and penicillium spp. The antifugal activity of onions was less marked while its water extracts showed no activity. The lack of inhibition on Neurospora clasa was conspicuous for both the garlic (Allium sativum) and Onions (Allium cepa) extracts. The commercial drugs were significantly more active against the tested fungi (MIC range 1.56-50ug/ml). Fulcin showed more activity than the rest of the commercial drugs tested. The activities of fulcrum for all the fungal species far surpassed those of nystatin and were even superior to those of Cotrimoxazole on Aspergillus niger and Aspergillus fumigatus. Nystatin showed a higher MIC range of 12.5-50 µg/ml for the tested fungal species. The MFC of the drugs was mostly 2-3 times their MIC values. These results suggest that overall, the fungal species tested showed more sensitivity to the commercially sold antifungals than that of the extracts.

Phytochemical screening was also performed. Results showed that highest (30 mm2) microbial zone of inhibition (MZI) observed in the extract of chloroform with Aeromonas sp. This followed by four strains, i.e., Bacillus cereus, B. pumilus, Proteus sp. and Salmonella typhi showed 28, 27, 25 and 24 mm2 MZI, respectively except water extract. The minimum inhibitory concentration (MIC) of all solvent extracts varied with different bacterial strains. The range of MIC was 50 mg/mL to 500 mg/mL, where highest 500 mg/mL MIC of all extracts observed against Pseudosomonas sp. followed by 100-500 mg/mL MIC against Salmonella typhi. Presence of flavonoids, alkaloids, glycosides, phytosterols, phenol, tannin, terpenoids and saponins confirmed by qualitative analysis. High solubility of tannins and terpenoids in chloroform demonstrated the effectiveness of metabolites against bacterial strains

Semen Cannabis and Oleum Hyperici: Antileishmanial activity against Leishmania tropica promastigotes and intracellular amastigotes

The exploration of alternative agents and novel drug candidates for the effective treatment of cutaneous leishmaniasis has garnered significant attention, driven by the high cost, toxic effects, and the emergence of drug resistance associated with current therapeutic options. Plant extracts derived from Semen Cannabis, the seeds of the Cannabis sativa L. (hemp) plant, and Oleum Hyperici, the oily macerate of Hypericum perforatum L. (St. John's Wort) plant, were prepared by using solvents of varying polarity (n-hexane, chloroform, ethanol, and 60% aqueous ethanol). The primary objective of this study was to research in vitro and ex vivo antileishmanial efficacy of Semen Cannabis and Oleum Hyperici plant extracts against Leishmania tropica promastigotes and intracellular amastigotes. The efficacy of plant extracts against promastigotes were assessed using the cell counting by hemocytometer and the CellTiter-Glo assay. Additionally, their impact on infected THP-1 macrophages and the quantity of intracelluler amastigotes were investigated. Cytotoxicity was evaluated in THP-1 macrophages. Among the tested plant extracts, chloroform extract of Oleum Hyperici demonstrated significant antileishmanial activity against promastigotes (SI: 12.6) and intracellular amastigotes (SI: 16.8) of L. tropica without inducing cytotoxic effects and hold promise for further investigation as potential antileishmanial agents.
