... Hasil analisis fitokimia disajikan pada Tabel 1. Uji fitokimia pada ekstrak terstandarisasi daun ginseng jawa menunjukkan hasil positif kandungan senyawa flavonoid, saponin, tanin, alkaloid, dan kuinon (Setyani dkk, 2016). Studi fitokimia pada ekstrak seluruh bagian tanaman Talinum fruticosum menunjukkan adanya kandungan glikosida, flavonoid dan karbohidrat (Sebastin et al., 2018). Senyawa flavonoid, fenolik dan saponin ditemukan pada hasil uji fitokimia daun kolesom (Talinum triangulare (Jacq). ...

Shigella sonnei merupakan salah satu bakteri patogen penyebab disentri basiler dengan tingkat prevalensi tinggi di negara berkembang. Bakteri ini dilaporkan resisten terhadap beberapa antibiotik yang direkomendasikan WHO, sehingga diperlukan upaya pencarian senyawa antibakteri baru. Penelitian ini bertujuan untuk mendeskripsikan kandungan fitokimia dan potensi ekstrak etanol umbi, batang dan daun ginseng jawa (Talinum paniculatum) dalam menghambat pertumbuhan S. sonnei secara in vitro. Uji fitokimia ekstrak etanol menggunakan metode Kromatografi Lapis Tipis (KLT). Potensi antibakteri dilakukan dengan menerapkan metode difusi cakram Kirby Baeur teknik swab dengan perlakuan seri konsentrasi ekstrak 50%, 75% dan 100%, kontrol positif (tetrasiklin 20%), dan kontrol negatif (DMSO 10%) dengan 5 pengulangan. Dari hasil uji fitokimia diketahui bahwa metabolit sekunder dari golongan steroid ditemukan pada umbi, batang maupun daun ginseng jawa. Flavonoid hanya ditemukan pada umbi dan daun. Ekstrak etanol batang dan daun menunjukkan hasil positif untuk tanin dan fenolik. Alkaloid, saponin dan terpenoid tidak ditemukan pada ketiga ekstrak tersebut. Ekstrak etanol daun memiliki potensi penghambatan terhadap S. sonnei lebih besar dibandingkan umbi dan batang, terutama pada konsentrasi 100%. Meskipun demikian zona hambat yang terbentuk masih belum cukup efektif jika dibandingkan dengan zona hambat yang dibentuk oleh kontrol positif yaitu tetrasiklin. Shigella sonnei a pathogenic bacterium that causes bacillary dysentery – a disease with high prevalence in developing countries. This bacterium has been reported resistant to several antibiotics. Development of new antibacterial compounds is regarded necessary. This study was conducted to describe the phytochemical content and potentials of ethanol extract from the tubers, stems and leaves of fameflowers (Talinum paniculatum) in inhibiting the growth of S. sonnei in vitro. Phytochemical test was performed to the ethanol extract using Thin Layer Chromatography (TLC). Antibacterial potential was assessed using Kirby Baeur disc diffusion swab on different treatment concentrations of 50%, 75% and 100% with positive control (20% tetracycline), and negative control (DMSO 10%) in 5 replications. The phytochemical tests showed that secondary metabolites from the steroid group were found in tubers, stems and leaves of the famefolowers. However, flavonoids were only found in tubers and leaves. The ethanol extracts of stems and leaves also contained tannins and phenolics. Furthermore, neither Alkaloids, saponins or terpenoids were found in the three extracts. In addition, ethanol extract from the leaves showed stronger inhibitory potential against S. sonnei extracts from tubers and stems, particularly at 100% concentration. However, the inhibition zone formed in the extracts was still less effective compared to the inhibition zone formed by tetracycline as positive control.
The present study focuses on a facile phytosynthesis to develop C. amada-coated ZnO nanoparticles from zinc acetate dihydrate solution by using Talinum fructicosum leaf as reducing agent. The phenolic content of C. amada along with curcuminoid compounds (such as de- and bis-methoxy curcumin), function as a surface-active source to produce high-quality ZnO nanostructures. The X-ray diffraction (XRD), BET Surface area analysis (BET), X-ray photoelectron spectroscopy (XPS), UV–Visible spectral analysis (UV), Fourier transform infrared spectroscopy (FTIR), antimicrobial, antidiabetic, bovin serum albumin denaturation assay, electrochemical analysis (ES), photocatalytic degradation and catalytic reduction potential evaluation were used to characterize the phyto-synthesised ZnO nanoparticles. The XRD pattern exhibited a good nanocrystallinity with hexagonal wurtzite structure and an efficient band gap of 3.33 eV which further proved the ZnO nanoparticles to be a good semiconductor. FTIR analysis and XPS studies mutually prove the Zn–O bond formation; BET analysis confirmed the configuration of ZnO, with the surface area of 11.488 m2/g, which is mesoporous in nature and highlighted the significance of the porous morphology in SEM findings. The study specially focuses on illustrating the symmetric supercapacitor electrode based on ZnO nanoparticles with a superior specific capacitance value of 457 F g−1 (1 A g−1). The photodegradation of methylene blue and methyl orange dyes demonstrated a maximum degradation efficiency of 97 and 91%, respectively, achieved after 90 minutes of irradiation, emphasizing the influence of an increased concentration of biomolecules. Additionally, ZnO nanoparticles exhibited effective catalytic reduction potential on highly toxicious 4-nitrophenol to get reduced into less hazardious 4-aminophenol. The broad range of functionalities enhances the utility of biogenic ZnO nanoparticles and widens its scope for energy and environmental applications.
