“…Serbuk magnesium (Mg) mereduksi inti benzopiron pada flavonoid dan membentuk garam flavilium. Sementara itu, penambahan asam klorida (HCl) menyebabkan terhidrolisisnya senyawa flavonoid menjadi aglikon O-glikosil, dan suasana asam yang terbentuk setelahnya dapat memicu tereduksinya garam flavinium sehingga menyebabkan perubahan warna larutan menjadi merah (Marwati et al, 2020;Parbuntari et al, 2018;Ramayani et al, 2020;Supriadin et al, 2021).…”

Pityriasis versicolor is a disease caused by Malassezia furfur. One of the plants that can potentially act as antifungal is cacao leaves (Theobroma cacao L.), which contain several secondary metabolite compounds, including alkaloids, flavonoids, tannins, quinones, terpenoids, and saponins. This study aims to determine the phytochemical analysis and the Minimum Inhibitory Concentration (MIC) and Minimum Fungicidal Concentration (MFC) of cacao leaves ethanolic extract against M. furfur. Extracts were obtained by maceration using 70% ethanol and phytochemicals analysis using Herborne’s method. Furthermore, the extracts were made into concentrations’ variations of 3.125%; 6.25%; 12.5%; 25%; 50%; and 100% for testing antifungal activity, with 10% DMSO as negative control and 2% Ketoconazole and Itraconazole as positive controls. MIC was performed with liquid macrodilution method, and MFC was performed with spread method. The results of phytochemical analysis showed that the extract contained alkaloids, flavonoids, phenols, tannins, quinones, terpenoids and saponins. MIC value was obtained at concentration of 50% and MFC value was obtained at 100%. Cacao leaves ethanolic extract with concentration of 50% can inhibit M. furfur’s growth and with 100% can eliminate M. furfur.

Wuluh starfruit leaves have a very high antioxidant content. Antioxidants are substances that can reduce speed, postpone, or stop lipids from oxidizing or other easily oxidized components from oxidizing. The precise extraction time can have an impact on antioxidant activity. The purpose of this study was to investigate the effect of extraction time in the Microwave Assisted Extraction (MAE) technique on the antioxidant activity of wuluh starfruit leaf extract, as well as the precise extraction time in the MAE technique for producing the highest antioxidant activity starfruit leaf extract. The study employed a fully randomized design (CRD) with extraction time treatment levels of 3,5,7,9,11, and 13 minutes. There were 18 experimental units with three repetitions of each treatment. The Duncan Multiple Range Test (DMRT) was used to determine if the therapy had any impact on the parameters after the data were subjected to analysis of variance. The findings demonstrated that the yield, total phenol contents, total flavonoids contents, total tannin contents, total vitamin C contents, and IC50 were significantly influenced by the extraction duration. The best extraction time for wuluh starfruit leaves extract used the MAE method was 5 minutes with a yield of 26.75%, total phenol 621.60 mg GAE/g, total flavonoids 321.52 mg QE/g, total tannins 298.83 mg TAE/g, total vitamin C 595.44 mg AAE/g and IC50 28.35 ppm.

“…Analisis data pada penelitian ini menggunakan uji analisis parametik yakni dengan metode analisis uji ANOVA satu arah (One Way Anova). Berdasarkan hasil yang didapatkan menunjukkan bahwa perbedaan penggunaan jenis pelarut pada saat ekstraksi memberikan pengaruh secara signifikan terhadap kadar flavonoid total yang dihasilkan daun sirsak dan hasil persen randeman ekstrak tertinggi didapatkan oleh pelarut metanol, dimana semakin tinggi randeman ekstrak yang diperoleh maka semakin tinggi kadar senyawa yang terkandung dalam ekstrak (Ramayani et al, 2021). Pelarut metanol secara signifikan dapat menghasilkan kadar flavonoid total lebih tinggi dibandingkan dengan pelarut etanol 70%.…”

Latar Belakang: Daun Sirsak (Annona muricata Linn) secara empiris digunakan untuk mengobati berbagai macam penyakit. Salah satu potensi daun ini sebagai antioksidan karna mengandung senyawa flavonoid. Penelitian menggunakan pelarut yang bersifat polar yakni etanol 70% dan metanol untuk mengekstraksi senyawa flavonoid pada daun sirsak, penggunaan jenis pelarut berbeda akan mempengaruhi kadar flavonoid total yang dihasilkan. Tujuan: Mengetahui pengaruh perbedaan jenis pelarut etanol 70% dan metanol terhadap kadar flavonoid total daun sirsak serta deteksi kualitatif senyawa flavonoid. Metode: Penelitian menggunakan metode pre eksperimental, pembuatan ekstrak daun sirsak menggunakan metode maserasi dengan membandingkan pelarut etanol 70% dan metanol selanjutnya senyawa flavonoid dideteksi secara kualitatif menggunakan pereaksi warna dan kromotografi lapis tipis, kemudian penentuan kadar flavonoid dengan Spektrofotometri UV-Vis dan data dianalisa dengan uji One Way Anova. Hasil: Hasil uji deteksi kualitatif senyawa flavonoid daun sirsak menunjukkan hasil positif dan kadar flavonoid total yang dihasilkan oleh ekstrak etanol 70% dan metanol daun sirsak adalah 6,79 mg QE/g dan 9,25 mg QE/g. Hasil analisa uji One Way Anova menunjukkan perbedaan jenis pelarut berpengaruh signifikan terhadap kadar flavonoid total ekstrak daun sirsak. Kesimpulan: Perbedaan jenis pelarut berpengaruh signifikan terhadap kadar flavonoid total ekstrak daun sirsak dengan kadar tertinggi dihasilkan pelarut metanol sebesar 9,25 mg QE/g.
