Abstract

Metode Microwave-Assisted Extraction (MAE) digunakan untuk mengekstraksi senyawa flavonoid dari simplisia alga coklat Padina australis . Sampel diperoleh dari Pantai Bayah, Banten Indonesia. Kondisi optimal ekstraksi ditentukan dengan Response Surface Methodology (RSM). Desain Box-Behnken (BBD) digunakan untuk mengevaluasi pengaruh 3 faktor dengan 3 level yaitu daya microwave (300, 450, 600 watt), konsentrasi etanol  (30, 50, 70%), dan waktu ekstraksi (7, 8 dan 9 menit) dengan 15 perlakuan yang berbeda. Hasil disain eksperimen dengan BBD menunjukkan kondisi ekstraksi optimum yaitu pada daya microwave 414 watt, konsentrasi etanol 50,33% dan waktu ekstraksi 7,89 menit menghasilkan kadar prediksi flavonoid sebesar nilai 0,2963%. Nilai ini mendekati nilai kadar flavonoid yang diperoleh secara eksperimental sebesar 0,2961%, pada kondisi menggunakan daya microwave sebesar 450 watt, konsentrasi etanol 50% dengan lama ekstraksi 8 menit. Berdasarkan hasil penelitian, kadar flavonoid total dapat meningkat secara signifikan dengan melakukan optimasi proses MAE menggunakan RSM. Optimization of Microwave-Assisted Extraction for Total Flavonoid Content of Padina australis Brown Algae. Microwave-Assisted Extraction (MAE) was done to extraction flavonoid from Padina australis brown algae simplicial. The sample collected from Bayah coastal waters, Banten Indonesia. Optimum extraction condition was determined by the response surface methodology (RSM). The Box-Behnken design (BBD) was used to evaluate the influence of 3 factors with 3 levels extraction that is microwave power (300, 450, 600 watts), ethanol concentration (30, 50, 70%), and extraction time (7, 8 and 9 minutes) with 15 different runs. The research showed that optimum extraction condition was at 414 watts of microwave power, 50.33% ethanol concentration, and time extraction of 7.89 minutes yielded a predicted value of total flavonoid content of 0.2963%. This value approaches to the flavonoid content obtained experimentally at 0.2961% under condition of 450 watts microwave power, 50% ethanol concentration, and time extraction of 8 minutes. Based on the result, total flavonoid content can be significantly increased by optimizing the MAE process use RSM.
采用微华辅助提取法(MAE),从澳大利亚单藻中提取类黄酮化合物。样本来自印尼班顿的Bayah海滩。最佳提取条件是由病理表面反应(RSM)决定的。boxbi - nken (BBD)设计用于评估三级微波功率(300、450、600瓦)、乙醇浓度(30、50、70%)和提取时间(7、8和9分钟)对15种不同治疗的影响。BBD的实验结果显示,在414瓦的微波中提取的最佳状态,乙醇浓度为50.33%,提取时间为7.89分钟,为0.2963%。这种值接近实验中获得的0.2961%的类黄酮水平,在使用450瓦瓦的微波条件下,它的乙醇浓度为50%,提取时间为8分钟。研究发现,使用RSM进行MAE过程优化可以大大提高类黄酮的总水平。采用微效辅助工具进行全黄质配料澳洲航空。从澳大利亚的帕德纳布朗喜剧公司进行了微华人工制品的提取。样品收集自Bayah海岸水域,班滕印度尼西亚。优胜性是由反应表面卫理公会所决定的。拳击手设计(BBD)被用来评估三层微波炉(300、450、600瓦)、乙醇集中精神(30、50、70%)和撤离时间(7、8、9分钟)和15次不同的跑步。研究表明,最优化的微波功率为414瓦,53.33%的乙醇集中,耗时7分钟,耗时总量为0.2963%。这值相当于450瓦微波动力0.2961%基于结果,总黄磷含量可能因其乐观使用RSM进程而显著增加。
