“…Importantly, scCO 2 is regarded as a green technology [ 174 , 176 ]. While the equipment necessary for scCO 2 processing is not cheap, it is a process in which the oxidation of the target molecules is minimal [ 177 ]. Due to the fact that scCO 2 is a non-polar solvent, it is optimal for the extraction of non-polar and weakly polar compounds [ 178 , 179 ].…”

Plants produce a variety of high-value chemicals (e.g., secondary metabolites) which have a plethora of biological activities, which may be utilised in many facets of industry (e.g., agrisciences, cosmetics, drugs, neutraceuticals, household products, etc.). Exposure to various different environments, as well as their treatment (e.g., exposure to chemicals), can influence the chemical makeup of these plants and, in turn, which chemicals will be prevalent within them. Essential oils (EOs) usually have complex compositions (>300 organic compounds, e.g., alkaloids, flavonoids, phenolic acids, saponins and terpenes) and are obtained from botanically defined plant raw materials by dry/steam distillation or a suitable mechanical process (without heating). In certain cases, an antioxidant may be added to the EO (EOs are produced by more than 17,500 species of plants, but only ca. 250 EOs are commercially available). The interesting bioactivity of the chemicals produced by plants renders them high in value, motivating investment in their production, extraction and analysis. Traditional methods for effectively extracting plant-derived biomolecules include cold pressing and hydro/steam distillation; newer methods include solvent/Soxhlet extractions and sustainable processes that reduce waste, decrease processing times and deliver competitive yields, examples of which include microwave-assisted extraction (MAE), ultrasound-assisted extraction (UAE), subcritical water extraction (SWE) and supercritical CO2 extraction (scCO2). Once extracted, analytical techniques such as chromatography and mass spectrometry may be used to analyse the contents of the high-value extracts within a given feedstock. The bioactive components, which can be used in a variety of formulations and products (e.g., displaying anti-aging, antibacterial, anticancer, anti-depressive, antifungal, anti-inflammatory, antioxidant, antiparasitic, antiviral and anti-stress properties), are biorenewable high-value chemicals.

“…Temperatur ekstraksi yang lebih tinggi juga dapat berpotensi menyebabkan senyawa-senyawa yang termolabil dapat terdekomposisi (Pieczykolan et al, 2019). CO2 memiliki temperatur kritik yang rendah (31,1 o C mendekati temperatur ruang), sehingga kondisi operasi untuk ekstraksi zat termolabil tidak memerlukan nilai yang tinggi.…”

Plumeria obtusa frangipani flowers grow across Indonesia abundantly and are frequently used in Hindu religious ceremonies. However, fallen and used frangipani flowers could potentially cause an immense amount of flower waste on the ground and water. A preliminary study on the processing of the fresh flowers into essential oils by supercritical CO2 extraction had been done, however an evaluation of the extraction conditions (temperature and pressure) of P. obtusa has not yet performed. This work investigated the effect of extraction's pressure (100 and 300 bar) and temperature (40 and 60 o C) to the essential oil's yield and composition. The result showed that the high pressure of 300 bar and low temperature of 40 o C gives the highest yield (0,736%) with 36 compounds identified. Among them, 81% of their biological and pharmacological activities and benefits had been reported (antibacterial, antifungal, aromatic compound, antioxidant, antimicrobial, anti-inflammatory). The identification of composition of the flower essential oils showed that olean-12-ene, 3-methoxy-, (3β) (35,12%) was found only at 300 bar and 40 o C. This result confirmed that supercritical CO2 extraction was more specific in extracting volatile compounds from essential oils.

“…In fact, the absence of light and oxygen avoids oxidation and loss of biochemical activity of the extracts. Yet, it might not be a preferred industrial technique due to the high costs of equipment and analysis process (Pieczykolan et al ., 2019). In addition, SCE requires a co‐solvent or polar modifier to extract polar compounds (such as phenolic compounds) that have a low solubility in supercritical carbon dioxide.…”

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.
