Profile and Antioxidant Capacity of Phenolic Compounds from Rice Straw

ABSTRACTA study was conducted with the purpose of comparing antioxidant properties aquadest extracts three varieties red rice straw: Memberamo, Ciherang, and Barak Cenana. The extraction done using ultrasound-assisted (UAE) technique. compound profiling phenolic compounds in were by thin-layer chromatography (TLC) gas (GC). activity measurements DPPH FRAP assays, garlic acid as standard. total content assay showed no significant difference among straw varieties. TLC results two presumable flavonoids Memberamo Ciherang extracts, Cenana extract. GC analysis detected components extract, five six that extract indicated highest varieties, while Keywords: Antioxidant, compounds, straw, ABSTRAKPenelitian dilakukan untuk membandingkan sifat antioksidan dari ekstrak akuades jerami tiga varietas padi, yaitu padi dan Ekstraksi dengan metode (UAE). Penelitian profil senyawa fenolik dalam kromatografi lapis tipis (KLT) Pengukuran aktivitas uji menggunakan asam galat sebagai standar. kadar menunjukkan bahwa tidak ada perbedaan signifikan antara ketiga padi. Hasil KLT dua yang diduga golongan flavonoid pada serta Analisis mendeteksi komponen lima enam Uji tertinggi dimiliki oleh Cenana, sedangkan siginifikan Antioksidan, fenolik,
