“…Recently, we demonstrated that subcritical water was very efficient to extract bioactive components, asiatic acid and asiaticoside, from Centella asiatica [17]. High yield of asiatic acid (7.8 mg/g) and asiaticoside (10 mg/g) can be extracted at 40 MPa and 523 K. Herein, we demonstrate that mangiferin from Mahkota Dewa can be extracted using subcritical water with high extraction yield.…”

Plants and algae are the main sources of natural bioactive compounds used in the food and pharmaceutical industries. It is very important to achieve an efficient and safe technique to recover bioactive compounds while maintaining their quality and properties. Subcritical water extraction is the most promising engineering approach that offers an environmentally friendly technique for extracting various compounds from plants and algae. Application of pressurized water and high temperature in subcritical phase is able to modify the dielectric constant and polarity of the solvent which then contributes to a better extraction process. The technique improves the mass transfer rate and preserves the biological potency of the extracts. This article reviews current studies on the extraction of bioactive compounds from various species of plants and algae using the subcritical water technique and discusses its effects and benefits for the food and pharmaceutical industries.

“…Indeed, there are restrictions in organic solvent use for green extraction technology as well as in organic farming. Moreover, it should be underlined that (i) aqueous extraction is efficient and less expensive in comparison to other solvents, nontoxic, and environmentalfriendly alternative to conventional extraction techniques; (ii) it is easy for both field application and market registration; (iii) organic solvents are phytotoxic for plants and, in addition, extra work is needed to remove them from the extract; (iv) other surfactant (e.g., tween, dimethyl sulfoxide) should be added to redissolve in water compounds extracted with other organic solvents, increasing the cost of the bio-effector; (v) the extraction yields of some bioactive components resulted better in water than ethanol at room temperature [35]; and (vi) the limitation of aqueous extraction can be reduced by increasing the temperature [36] which rises the water polarity [37]. Figure 2 shows the germination indexes (GI) after 48 h of incubation using different aqueous extraction ratios.…”

Background: Recently, a novel concept 'bio-effectors' rose on to describe a group of products that are able to improve plant performance rather than fertilizers. Agro-food processing residues and by-products potentially represent important sources of bio-effectors but they are currently not properly taken in consideration. To fulfill this gap, in these study, three food processing by-products: (i) brewers' spent grain, (ii) fennel processing residues, and (iii) lemon processing residues were chosen as bio-effector candidates. Raw materials were chemically characterized, and green extraction methodology was optimized by using water, ethanol, and their mixture based on the extraction yields. Aqueous extracts were used for seed germination bioassays on Lepidium sativum seeds to evaluate their potential bioactivities. Thereafter, the extracts were chemically characterized and metabolites were detected by 1D and 2D NMR spectroscopy. Results: Results are summarized as follows: (i) raw materials showed an interesting nutritional content; (ii) aqueous extraction resulted higher yield more than other used solvent; (iii) at high solvent extraction ratio, aqueous extracts were not phytotoxic but enhanced seed germination and root elongation; (iv) all aqueous extracts are differently rich in nutrients, amino-acids, sugars, and other low molecular weight molecule compounds.
