Application of response surface methodology to optimise extraction of malaysian propolis

Application of response surface methodology to optimise extraction of malaysian propolis / Emily Ooi Shi Yun
Kaedah permukaan tindak balas (RSM) telah digunakan secara meluas dalam pelbagai eksperimen untuk menilai kesan faktor-faktor yang pelbagai serta menentukan keadaan yang optimum untuk semua parameter bagi mendapatkan reaksi yang wajar. Dalam kajian ini, RSM telah digunakan untuk mengoptimumkan keadaan operasi bagi pengekstrakan propolis Malaysia. Eksperimen telah dijalankan untuk menganalisis kesan dari pelbagai faktor seperti suhu pengekstrakan, kepekatan pelarut dan nisbah pepejal-kepada-pelarut atas hasil pengekstrakan propolis. Dalam hal hasil pengeluaran keseluruhan, tiada satu pun daripada tiga faktor memberi kesan yang signifikan (p > 0.1). Untuk kajian daripada jumlah kandungan fenolik, nisbah pepejal-kepada-larutan adalah satu-satunya parameter yang menunjukkan kesan yang signifikan (p < 0.05). Kepekatan pelarut adalah satu-satunya pembolehubah yang menyumbang kepada kesan yang signifikan (p < 0.05) pada jumlah flavones yang dikeluarkan. Dapatan keseluruhan menunjukkan bahawa tiada kesan interaktif yang ketara dapat diperhatikan antara ketiga-tiga pembolehubah yang dikaji. Hasil uji kaji yang dijalankan ini menunjukkan bahawa kandungan antioksidan propolis Malaysia adalah setanding dengan negara-negara jiran, Thailand dan Indonesia. Di samping itu, propolis Malaysia yang berunsur tropika menunjukkan prestasi yang baik dari segi kuantiti semasa koleksi kerana ia boleh didapati sepandjang tahun. _______________________________________________________________________________________________________ Response surface methodology (RSM) had been widely employed in various experiments to evaluate the effects of factors and determine optimum condition of parameters for desirable responses. In this research, RSM was applied to optimize the operating condition for the extraction of the Malaysian propolis. Experiments were conducted to analyse the impact of various factors such as the extraction temperature, solvent concentration and solid-to-solvent ratio, on the yield of the propolis extraction. In the case of the total extraction yield, none of the three factors gave a significant (p > 0.1) effect. For the study of total phenolic contents, solid-tosolvent ratio was the only parameter to show a significant (p < 0.05) effect. Solvent concentration was the only variable which contributed to the significant (p < 0.05) impact on the total flavones extracted. The overall finding showed that no substantial interactive effect was observed between the three variables studied. The yield of the conducted experimentation showed that the antioxidant content of the Malaysian propolis was comparable to those of the neighbouring countries, Thailand and Indonesia. In addition, the tropical Malaysian propolis fared well in terms of quantity during its collection as it is available throughout the year.
