Alternative Methods of Bioactive Compounds and Oils Extraction

Berry fruit by-products are a source of polyphenol compounds and highly nutritious oils and can be reused to fulfill the requirements of the circular economy model. One of the methods of obtaining polyphenol-rich extracts or oils is extraction. Applying conventional solvent extraction techniques may be insufficient to reach high polyphenol There are two types of MAE methods: solvent-free extraction (usually for volatile compounds) and solvent extraction (usually for non-volatile compounds) [36, 37]. Chen optimized the conditions for MAE to extract resveratrol ( 60,Fig. 9 ) from the TCM Polygoni Cuspidati Rhizoma et Radix (the rhizome and radix of Polygonum cuspidatum ) Techniques for extraction and isolation of natural products: a

The Application of Supercritical Fluid Extraction in Phenolic Compounds

The separation of phenolic compounds by supercritical fluid extraction has been widely studied throughout the last two decades. This is evidenced by a number of publications and articles. Supercritical fluid extraction (SFE) has become thus the effective method of separating the mentioned group of compounds. On the other hand, SFE is a Clitoria ternatea plant is commonly grown as an ornamental plant and possesses great medicinal value. Its flower is edible and also known as blue pea or butterfly pea flower. The unique feature of anthocyanins present in blue pea flowers is the high abundance of polyacylated anthocyanins known as ternatins.
