| dc.description.abstract | Bunga jengger ayam (Celosia cristata L.) merupakan tanaman tropis Asia
yang kaya akan senyawa fenolik dan flavonoid dengan potensi antioksidan tinggi.
Penelitian ini bertujuan menyeleksi genotipe terbaik berdasarkan kadar total
fenolik, flavonoid, dan aktivitas antioksidan dari ekstrak etanol bunga jengger
ayam. Pemilihan genotipe unggul mengoptimalkan potensi antioksidan dan obat.
Empat belas genotipe bunga jengger ayam diekstraksi dengan etanol 96%
menggunakan metode Microwave Assisted Extraction (MAE), lalu diuji TPC
menggunakan Folin-Ciocalteu dan TFC menggunakan aluminium klorida. Hasil
penelitian menunjukkan bahwa kadar fenolik total, kadar flavonoid total, dan
kapasitas antioksidan FRAP diperoleh pada genotipe yang sama yaitu 3-4m-1m,
sedangkan kapasitas antioksidan tertinggi pada pengujian DPPH ditunjukkan pada
genotipe 3-4m-4m. Uji statistik mengonfirmasi perbedaan signifikan antar sampel,
dengan korelasi kuat antara TPC, TFC dan FRAP, serta korelasi lemah antara TPC,
TFC dan DPPH. Genotipe terbaik berdasarkan keempat uji yang dilakukan yaitu 3
4m-1m. Heatmap mempermudah identifikasi pola korelasi antar variabel. | |
| dc.description.abstract | Cockscomb flower (Celosia cristata L.) is a tropical Asian plant rich in
phenolic and flavonoid compounds with high antioxidant potential. This study
aimed to select the best genotype based on total phenolic content (TPC), total
flavonoid content (TFC), and antioxidant activity from ethanol extracts. Superior
genotype selection enhances antioxidant and medicinal potential. Fourteen
genotypes of cockscomb flower were extracted using 96% ethanol with the
Microwave Assisted Extraction (MAE) method, followed by TPC analysis with
Folin-Ciocalteu and TFC with aluminum chloride. Results showed that the highest
TPC, TFC, and FRAP values were found in the same genotype, 3-4m-1m, while the
highest DPPH antioxidant activity was observed in genotype 3-4m-4m. Statistical
tests confirmed significant differences among samples, with strong correlations
among TPC, TFC, and FRAP, and weak correlations with DPPH. Genotype 3-4m
1m was identified as the best across all tests. The heatmap facilitated identification
of correlation patterns among variables. | |
