Abstract

The sunscreen test of fraction n-hexane, chloroform, and ethyl acetate of ethanol 96% flamboyant leaf (Delonix regia. Raf) extract had been performed. This research begins the extraction of a flamboyant leaf using 96% ethanol. Extraction used the maceration method. The extract is fractionation with some solvents such as n-hexane, chloroform, and ethyl acetate. Each fraction was identified secondary metabolite and sunscreen test involving SPF, %Te, and %Tp measurement using UV-Vis Spectrophotometer. The result of phytochemical screening exhibited flavonoids, alkaloids, saponins, tannins, and phenolics in ethyl acetate fraction. n-hexane and chloroform fraction don't show saponins and flavonoid content. The sunscreen test shows that chloroform fraction has good protection power toward UV light with SPF, %Te, and %Tp value is 54.27±0.462, 7.46±0.473, and 12.83±0.047 in 250 mg/L, respectively.

Abstract

Telah dilakukan penelitian tentang skrining fitokimia pada ekstrak daun flamboyan (Delonix regia. Raf). Penelitian ini bertujuan untuk mengetahui senyawa metabolit sekunder pada ekstrak daun flamboyan meliputi flavonoid, alkaloid, saponin, tanin dan fenolik. Penelitian diawali dengan pembuatan ekstrak metanol, kloroform dan n-heksan daun flamboyan menggunakan metode maserasi. Masing-masing ekstrak selanjutnya dilakukan skrining fitokimia. Hasil skrining fitokimia menunjukkan semua ekstrak daun flamboyan mengandung flavonoid, alkaloid, tanin dan fenolik. Kandungan saponin tidak terdapat pada ekstrak kloroform dan n-heksan sedangkan hasil positif saponin terdapat pada ekstrak methanol daun flamboyan. Kata Kunci: Daun Flamboyan (delonix regia. Raf), Skrining Fitokimia, Metabolit Sekunder

Abstract

Telah dilakukan sintesis lempung terinterkalasi anilin dan pemanfaatannya sebagai adsorben fenol. Penelitian bertujuan untuk mengetahui karakteristik lempung terinterkalasi anilin dan kemampuannya dalam mengadsorpsi fenol. Penelitian meliputi preparasi lempung, pembuatan Na-Lempung dan sintesis lempung terinterkalasi anilin. Produk yang dihasilkan dikarakterisasi menggunakan spektroskopi Fourier Transform-Infrared (FTIR), difraksi sinar-X (XRD) dan luas permukaan menggunakan metode metilen biru. Selanjutnya produk tersebut digunakan untuk mengadsorpsi fenol. Hasil karakterisasi menggunakan FTIR menunjukkan serapan NH pada 3430,22 cm-1, serapan CN pada 2358,01 cm-1 dan terdapat beberapa gugus yang tetap dipertahankan pasca interkalasi. Analisa XRD menunjukkan bahwa interkalasi anilin menurunkan basal spacing 4,81 Ǻ untuk lempung alam menjadi 4,47 Ǻ untuk lempung terinterkalasi anilin diikuti penurunan luas permukaan 816,46 m2/g untuk lempung alam menjadi 789,63 m2/g pada lempung terinterkalasi anilin. Hasil penelitian mengindikasikan bahwa lempung terinterkalasi anilin dapat mengadsorpsi fenol dengan baik dibandingkan lempung alam. Hal ini sejalan dengan nilai kapasitas adsorpsi fenol oleh lempung terinterkalasi anilin yaitu 100,00 μmol/g yang lebih besar dari lempung alam (71,43 μmol/g). Kata Kunci: lempung, anilin, interkalasi, adsorpsi.

Abstract

The regulation of proliferation and apoptosis in cancer cells, particularly breast cancer, hinges on the control exerted by the epidermal growth factor receptor (EGFR). Naturally derived EGFR inhibitors from natural compounds show significant potential for future advancements. This study aims to assess the efficacy of active compounds found in Ageratum Conyzoides L as EGFR inhibitors. Evaluation involved molecular docking studies of flavonoid, chromene, terpene, sterol, and acid compounds against EGFR using PDB ID 1m17. Additionally, the ADMET properties and drug-like characteristics of the most promising compounds were characterized. Findings reveal that compound C2 (fisetin) exhibits the most favorable binding energy of -8.9 kcal/mol. Fisetin establishes crucial interactions, particularly with the catalytic site at Met765 of the hinge protein. Fisetin also engages in hydrophobic interactions in regions I and II, involving Val702, Leu694, and Leu820. ADMET profiling of fisetin demonstrates favorable attributes, suggesting its potential as a promising anticancer agent based on drug-likeness assessments.
