Embodiment 1

[0357] Example of Step 1A: Single-step SFE maximum extraction and purification of elderberry

[0358] All SFE extractions were performed on SFT 250 (Supercritical Fluid Technologies, Inc., Newark, Delaware, USA) with a design pressure and temperature of up to 690 bar and 200°C, respectively. The device allows simple and effective extraction in dynamic or static mode operation flexibly under supercritical conditions. The device is mainly composed of three modules; oven, pump and controller, and collection module. The oven has a preheating column and a 100ml extraction vessel. The pump module has a compressed air driven pump with a constant flow rate of 300ml / min. The collection module is a 40ml glass bottle sealed with a cap and a septum for the recovery of the extracted product. The equipment is equipped with micro metering valves and flow meters. The pressure and temperature of the extraction vessel are monitored and controlled within ±3 bar and ±1°C.

[0361] Example of Step 2: Water Alcohol Extraction

Embodiment 3

[0364] Example of Step 3: Affinity adsorbent extraction of phenolic acid fraction (F1-F4 and F1-F6 fraction preparation)

[0365] In a typical experiment, the working solution is a transparent hydroalcoholic solution of the extract from the elderberry species in ethanol solution in step 2. The affinity adsorbent polymer resin is XAD7HP or ADS5. Before and after filling the column with ID 25mm and length 500mm, pre-wash 15gm ADS5 affinity adsorbent or 20gm XAD7HP affinity adsorbent with 95% ethanol (4-5BV) and distilled water (4-5BV) . The loaded solution is a crude 80% ethanol leaching phenolic acid solution, in which the chemical components are concentrated by rotary vacuum distillation and ethanol recovery. For XAD7HP loading, the final loading solution concentration was 29.03mg / ml, and for ADS5 loading, its concentration was 34.90mg / ml. At a flow rate of 0.3 BV / hr, 50 ml of the loading solution was loaded on the XAD7HP column, and 60 ml of the loading solution was loaded on t...
