Advanced extraction techniques for Berberis species phytochemicals: A review

Abstract

Summary Berberis species are known for their functional and nutraceutical properties. For example, different Berberis species have shown a wide range of pharmacological activities and they have been used in food industries as additives, preservatives and antioxidants. The functional property of any herb is influenced by many factors including the extraction process of its active components. Consequently, new extraction methodologies have been investigated to increase the efficiency of extracting bioactive compounds. In this review, we examine all the recent extraction techniques and advanced technologies that have been applied for the extraction of phytochemicals from different Berberis species. The five following techniques have been included for this purpose: ultrasound‐, microwave‐, pulsed electric field‐assisted, supercritical carbon dioxide and subcritical water extraction. These techniques have been used to extract phenolics, flavonoids, anthocyanins and berberine from different parts of various Berberis species which include B. vulgaris, B. jaeschkeana, B. aristata, B. integerrima, B. dasystachya and B. koreana. Microwave‐assisted extraction (MAE) has been well studied, optimised and evaluated. Yet, the present research considering other techniques are limited, and require further investigation and optimisation. In addition, the application of green solvents such as natural deep eutectic solvents could be considered in further developing MAE.

Phytochemical Characterization, Antioxidant Activity, and Cytotoxicity of Methanolic Leaf Extract of Chlorophytum Comosum (Green Type) (Thunb.) Jacq

“…Of the powdered lyophilized leaves, 42.0 g was extracted with 420.0 mL of methanol for 14 days at room temperature (23 ± 0.5 °C). The extract was filtered through cheesecloth and paper filters and then dried using a rotary evaporator RV 10 Basic V (IKA, Germany) at a temperature of 45–50 °C until complete solvent removal [ 128 , 129 ]. The yield of dry matter was 7.0 ± 0.1 g.…”

Photochemical defense as trait of fungi from Cortinarius subgenus Dermocybe

“…All species produced singlet oxygen, as depicted in Supplementary Figure S11 and Table S3, with a relative photoactivity of at least 33 ± 15% (for C. ominosus) compared to the natural photosensitizer berberine. Extracts of the root of Berberis ilicifolia containing berberine [31] yielded a relative photoactivity value of 29% [6]. Evaluating just the complete basidiocarps, extracts from fungi of the Malicoria pigmentation type (C. malicorius and C. rubrophyllus) were the most active, followed by those from the Sanguinea type and the Cinnamomea type.…”

Physiochemical, antioxidant, and food simulant release properties of collagen‐carboxymethyl cellulose films enriched with Berberis lyceum root extract for biodegradable active food packaging

“…from different Berberis species were studied. Berberis species are known for their nutraceutical and functional properties, and they have been used in food industries as additives, and preservatives (Ali Redha et al 2021).…”
