Abstract

Daun Piladang (Solenostemon scutellarioides) merupakan obat tradisional Sumatera Barat yang memiliki banyak kandungan metabolit sekunder berpotensi sebagai antioksidan. Metabolit sekunder seperti golongan fenolat yang terdapat pada fraksi polar umumnya terdapat dalam bentuk glikosida. Proses hidrolisis dapat memutuskan ikatan gula sehingga dapat melepaskan aglikon yang memiliki aktivitas antioksidan lebih tinggi daripada bentuk glikosidanya. Pada penelitian ini dilakukan hidrolisis asam terhadap fraksi air (polar) daun piladang, menggunakan asam asetat, asam fosfat dan asam klorida. Profil kimia fraksi hasil hidrolisis ditentukan secara kualitatif dengan KLT dan secara kuantitatif dengan metode Folin Ciocalteu untuk memperoleh kadar fenolat total.  Aktivitas antioksidan fraksi hasil hidrolisa diperiksa dengan metode perangkapan radikal DPPH. Hasil penelitian menunjukkan adanya perbedaan profil KLT dari masing-masing fraksi hasil hidrolisis. Kadar fenolat tertinggi diperoleh pada hidrolisis dengan asam fosfat yaitu 7,736 % diikuti asam klorida 4,218% dan asam asetat 2,024%. Aktivitas antioksidan tertinggi ditunjukkan pula oleh hasil hidrolisis dengan asam fosfat yaitu dengan IC50 413,92 ppm yang termasuk ke dalam kategori lemah.Piladang leaves (Solenostemon scutellarioides) is a traditional West Sumatra medicine which has a lot of secondary metabolite content which has the potential as an antioxidant. Secondary metabolites such as the phenolic group found in the polar fraction are generally in the form of glycosides. The hydrolysis process can break the bond of sugar so that it can release aglycone which has higher antioxidant activity than the form of glycosides. In this study,  the acid hydrolysis of the water fraction (polar) of piladang leaves was carried out using acetic acid, phosphoric acid and hydrochloric acid. The chemical profile of the hydrolysis fraction was determined qualitatively by TLC and quantitatively by the Folin Ciocalteu method to obtain total phenolic levels. The antioxidant activity of the hydrolysis fraction was examined by the DPPH radical scavenging method. The results showed a difference in the TLC profile of each hydrolysis fraction. The highest phenolic content was obtained by hydrolysis with phosphoric acid which was 7,736% followed by hydrochloric acid 4,218% and acetic acid 2,024%. The highest antioxidant activity was also shown by the results of hydrolysis with phosphoric acid, with IC50 413.92 ppm which was included in the weak category.

Abstract

Elephantopus mollis is a common weed found in West Sumatra, known for its diverse traditional uses and rich phytochemical content. This study aimed to isolate phenolic compounds and evaluate the antioxidant activity of the polar extract of E. mollis herb. The polar extract was obtained through successive extraction using solvents of increasing polarity. Separation of the polar extract was carried out using Amberlite XAD-4 resin chromatography with methanol and water eluents, followed by isolation through silica gel column chromatography using a step-gradient polarity elution system. The separation and isolation processes were monitored by thin-layer chromatography (TLC). Total phenolic content was determined by the Folin–Ciocalteu method, while antioxidant activity was assessed using the DPPH radical scavenging assay. Structural identification of the isolated compound was performed using UV-Vis, IR, NMR, and LC-MS spectroscopic techniques. Subfraction D of the polar extract exhibited a high phenolic content of 618.06 ± 3.38 mg GAE /g. From subfraction D, a phenolic compound designated D3a was isolated as a yellowish-white powder (95.30 mg) with an Rf value of 0.64, producing a dark blue color upon reaction with 10% FeCl₃. The antioxidant activity of compound D3a was classified as very strong, with an IC₅₀ value of 12.42 ppm. Based on physicochemical characterization, compound D3a was identified as caffeic acid with a molecular formula of C₉H₈O₄ and a molecular weight of 180.049.
