Abstract
Avocado seeds contain bioactive compounds such as
procyanidins, phenolic compounds, triterpenoids, acetogenins, amino
fatty acids, and weak acids that can be used as antioxidants.
Antioxidants are compounds that can inhibit oxidation and block
damaging production, as well as block ageing, inflammation, and
cancer. This study aims to determine the effect of solvent ratios, the
optimal solvent formula composition, and the total phenol content, total
flavonoids, and antioxidant activity of the optimal solvent in the
avocado seed extraction process.
The research method used the SLD (Simplex Lattice Design)
Design Expert method. The extract formula was prepared using
sonication, with the results showing 17 formulas for three solvents:
acetone, distilled water, and 70% ethanol. Test parameters included
phytochemical screening tests, specific and non-specific parameter
tests, total phenol tests, total flavonoid tests, and antioxidant activity
tests using the DPPH method. Statistical data analysis was performed
using Design Expert with ANOVA (Analysis of Variance) output
according to the designed experimental design.
The results obtained based on the research are the 12th run
formula with a solvent ratio of acetone, distilled water, and 70%
ethanol (100:0:0) has an extract yield of 3.25%, total flavonoids of
17.302 mgQE/g extract, total phenols of 46.274 mgGAE/g extract, and
antioxidant activity of 81.68 ppm, the optimisation results show that the
optimum solvent composition is 100% Acetone, without a mixture of
70% Ethanol or Distilled Water.
Biji alpukat mengandung senyawa bioaktif seperti procyanidin,
senyawa fenolik, triterpenoid, asetogenin, asam lemak amina, dan asam
lemah yang dapat digunakan sebagai antioksidan. Antioksidan adalah
senyawa yang dapat menghambat oksidasi serta memblokir produksi
yang merusak dan, memblokir penuaan, peradangan, dan kanker.
Penelitian ini bertujuan untuk mengetahui pengaruh dari perbandingan
pelarut, komposisi formula pelarut yang optimal, dan
kadar fenol total, flavonoid total, dan aktivitas antioksidan dari pelarut
yang optimal dalam proses ekstraksi biji alpukat.
Metode penelitian ini menggunakan desain metode SLD
(Simplex Lattice Design) Design Expert. Formula ekstrak dibuat
dengan metode sonikasi, hasil running menunjukkan 17 formula
terhadap tiga pelarut yaitu aseton, akuades, dan etanol 70%. Parameter
pengujian antara lain uji skrining fitokimia, uji parameter spesifik dan
non-spesifik, uji total fenol, uji total flavonoid, dan uji aktivitas
antioksidan dengan metode DPPH. Analisis data statistik dilakukan
menggunakan Design Expert dengan keluaran ANOVA (Analysis of
Variance) sesuai dengan desain eksperimen yang dirancang.
Hasil yang diperoleh berdasarkan penelitian adalah formula run
ke-12 dengan perbandingan pelarut aseton, akuades, dan etanol 70%
(100:0:0) memiliki rendemen ekstrak 3,25%, total flavonoid sebesar
17,302 mgQE/g ekstrak, total fenol sebesar 46,274 mgGAE/g ekstrak,
dan aktivitas antioksidan sebesar 81,68 ppm, hasil optimasi
menunjukkan bahwa komposisi pelarut optimum adalah 100% Aseton,
tanpa campuran Etanol 70% atau Akuades.
