Abstract

ABSTRAK TEKNOLOGI EKSTRAKSI FLUIDA SUPERKRITIS DAN MASERASI PADA ZINGIBER OFFICINALLE ROSCOE : AKTIVITAS ANTIOKSIDAN DAN KANDUNGAN FITOKIMIA. Proses ekstraksi Zingiber officinale Roscoe dengan metode fluida superkritis dan metode maserasi sebagai pembanding telah dilakukan. Ekstraksi CO 2 superkritis dilakukan pada kondisi proses tekanan 12-16 MPa, suhu 20-40 O C, waktu ekstraksi 2-6 jam dan laju alir fluida CO 2 superkritis 5,5 mL/menit. Pengaruh proses ekstraksi terhadap rendemen, aktivitas antioksidan dan kandungan fitokimia dari Zingiber officinale Rosc telah diteliti. Hasil penelitian ekstrak kasar jahe menunjukkan bahwa rendemen tertinggi 2,99 mg/g diperoleh pada suhu 40 O C, tekanan 16 MPa dan waktu ekstraksi 6 jam, dengan kandungan fenol total 72,73 mg GEA/g ekstrak, flavonoid total 0,90 % (b/b) dan aktivitas antioksidan sebesar 63,66 µg/mL. Hasil ekstrak kasar jahe dengan metode maserasi dihasilkan rendemen 3,10 mg/g, dengan kandungan phenol total 76,68 mg GEA/g ekstrak, flavonoid total 1,18 % (b/b) dan aktivitas antioksidan sebesar 122,85 µg/mL. ABSTRACT SUPERCRITICAL FLUID EXTRACTION TECHNOLOGYAND MACERATION OF ZINGIBER OFFICINALLE ROSCOE : ANTIOXIDANT ACTIVITY AND PHYTOCHEMICAL CONTENT. The process of extracting Zingiber officinale Roscoe with supercritical fluids and maceration method as a comparison has been done. CO 2 supercritical fluid at extractions were performed operating pressure in the range of 12-16 MPa, with temperature 20-40 o C, extraction time 2-6 hours and flow rate 5.5 mL/min. Effect of extraction to the yield, antioxidant activity and phytochemical content of Zingiber officinale Rosc was observed. Results showed that the crude extract from Zingiber officinale Rosc exhibits higher extraction yield with 2.99 mg/g was obtained at 40 o C, the pressure of 16 MPa and extraction time of 6 hours, with a phenol total content of 72.73 mg GEA/g extracts, flavonoid totals 0.90% (w/w) and activity antioxidants at 63.66 µg/mL. Results showed of ginger crude extract with maceration method resulting yield of 3.10 mg/g, with a phenol total content of 76.68 mg GEA/g extracts, flavonoid totals 1.18% (w/w) and antioxidant activity of 122.85 µg/mL.
