Abstract
Antioksidan yaitu senyawa yang menghambat oksidasi senyawa
lain. Biji buah alpukat mentega kaya akan senyawa fenolik, flavonoid
dan tanin. Senyawa tersebut diketahui sebagai antioksidan. Tujuan
penelitian ini untuk mengetahui potensi fraksi n-heksan, etil asetat, nbutanol
dan air dari ekstrak etanol 96% biji buah alpukat mentega. Serta
mengetahui golongan senyawa metabolit sekunder yang terkandung
dalam fraksi teraktif.
Serbuk biji alpukat mentega dimaserasi dengan pelarut etanol
96%. Ekstrak difraksinasi dengan pelarut n-heksan, etil asetat dan nbutanol.
Aktivitas antioksidan ekstrak dan fraksi diuji dengan metode
DPPH, intensitas warna larutan diukur menggunakan Spektrofotometer
UV-VIS. Identifikasi senyawa kimia fraksi teraktif dilakukan secara
KLT.
Hasil penelitian ini menunjukkan adanya potensi antioksidan
fraksi n-heksan, etil asetat, n-butanol, air dan ekstrak etanol 96% biji
alpukat mentega. Aktivitas antioksidan ekstrak, fraksi n-heksan, etil
asetat, n-butanol dan air berturut-turut yaitu 47.811 μg/mL, 66,91 μg/mL,
23.19 μg/mL, 39.86 μg/mL, 59.47 μg/mL. Golongan senyawa yang
terkandung dalam fraksi etil asetat antara lain adalah alkaloid,
triterpenoid, saponin dan flavonoid.
Antioxidants are compounds that inhibit the oxidation of other
compounds. Avocado seeds are rich in phenolic compounds, flavonoids
and tannins. This compound is known as an antioxidant. The aim of this
research was to determine the potential of n-hexane, ethyl acetate, nbutanol
and water fractions from 96% ethanol extract of butter avocado
seeds. As well as knowing the groups of secondary metabolite compounds
contained in the most active fraction.
Avocado seed powder is macerated with 96% ethanol solvent.
The extract was fractionated using n-hexane, ethyl acetate and n-butanol
as solvents. The antioxidant activity of extracts and fractions was tested
using the DPPH method, the color intensity of the solution was measured
using a UV-VIS spectrophotometer. Identification of the most active
fraction chemical compounds was carried out by TLC.
The results of this study indicate the antioxidant potential of nhexane,
ethyl acetate, n-butanol, water and 96% ethanol extract of
avocado seed butter. The antioxidant activity of the extract, n-hexane,
ethyl acetate, n-butanol and water fractions were 47,811 μg/mL, 66.91
μg/mL, 23.19 μg/mL, 39.86 μg/mL, 59.47 μg/mL, respectively. The
classes of compounds contained in the ethyl acetate fraction include
alkaloids, triterpenoids, saponins and flavonoids.
