Abstract

Telah dilakukan penelitian terhadap kandungan Pb dalam gorengan beserta minyaknya yang dijual di pinggir jalan di kawasan Kota Garut, yaitu wilayah Warung Peuteuy dan Terminal Guntur dengan membandingkan gorengan beserta minyaknya yang dimasak sendiri. Tahap awal dilakukan destruksi basah terhadap sample dan dianalisis menggunakan Spektrofotometri Serapan Atom. Hasil analisis menunjukkan bahwa semua sampel mengandung Pb, namun tidak melebihi ambang batas Pb dalam makanan berdasarkan peraturan BPOM RI No. 03725/B/SK/VII/1989 yaitu 2 ppm. Sampel produk gorengan mengandung logamPb dengan kisaran konsentrasi 2,7x10-5 ppm – 2,5x10-4 ppm dan sampel minyak goreng mengandung logamPb dengan kisaran konsentrasi 6,3x10-6 – 2,4x10-4 ppm. Pengambilan sampel dilakukan dengan 1, 5, 10, 15 kali penggorengan dan diambil pada jam sibuk yaitu pukul 16.00 WIB – 18.00 WIB. Kata kunci : Pb, gorengan, minyak, Spektrofotometri Serapan Atom

Abstract

Lignans are a group of phenylpropanoid dimers in which the phenylpropane units are linked by their propyl side chains' central carbon (C8). Lignans have various biological activities, including antiviral, anticancer, cancer preventive, and cytotoxic. Zanthoxylum rhetsa (Roxb.) DC is a tree with prickly branchlets belonging to the Zanthoxylum genus, commonly known as panggal buaya in Indonesia. Asian tribes have used this plant as traditional medicine. In this study, (+)-piperitol-γ,γ-dimethylallylether, a furofuran lignan, was successfully isolated. The chemical structure of compound 1 was determined based on spectroscopic data, including 1D- and 2D-NMR, mass spectroscopy, and by comparing with previous spectral data. In addition, compound 1 was tested for its cytotoxic activity against MCF-7 breast cancer cell lines in vitro and showed weak activity with the IC50 value of 261.37 µg/mL.
