“…Recent articles have demonstrated that various plant byproducts, such as fruit or vegetable pomace, bran/husk/seed coat, seeds, peel, and leaves, are important source of phytochemicals and can be utilised as innovative ingredient in foods [6][7][8][9][10][11][12][13][14][15][16][17]. Extracts obtained from various sections of the Annona squamosa plant, such as its bark, roots, leaf, stem, fruit, peel, and seeds, have been utilised in traditional pharmacological applications in different countries to cure a variety of diseases, such as dysentery, epilepsy, haemorrhage, fever, and tumours [2].…”

Annona squamosa L. (custard apple) belongs to the family Annonaceae and is an important tropical fruit cultivated in the West Indies, South and Central America, Ecuador, Peru, Brazil, India, Mexico, the Bahamas, Bermuda, and Egypt. Leaves of custard apple plants have been studied for their health benefits, which are attributed to a considerable diversity of phytochemicals. These compounds include phenol-based compounds, e.g., proanthocyanidins, comprising 18 different phenolic compounds, mainly alkaloids and flavonoids. Extracts from Annona squamosa leaves (ASLs) have been studied for their biological activities, including anticancer, antidiabetic, antioxidant, antimicrobial, antiobesity, lipid-lowering, and hepatoprotective functions. In the current article, we discussed the nutritional and phytochemical diversity of ASLs. Additionally, ASL extracts were discussed with respect to their biological activities, which were established by in vivo and in vitro experiments. A survey of the literature based on the phytochemical profile and health-promoting effects of ASLs showed that they can be used as potential ingredients for the development of pharmaceutical drugs and functional foods. Although there are sufficient findings available from in vitro and in vivo investigations, clinical trials are still needed to determine the exact effects of ASL extracts on human health.

“…The interaction effect of extraction time and microwave power shows a negative influence on the extraction yield of phenolic groups (TPC, TFC, Pro.A) and antioxidant properties (measured by FRAP, CUPRAC, ABTS, and DPPH) ( Table 2 ). The long exposure under high microwave power results in the eventual degradation of phenolics [ 33 ]. Liazid et al [ 34 ] also reported significant degradation of various phenolic groups after a certain temperature level rise during MAE.…”

The lemon-scented tea tree (LSTT) is an Australian native herb and is a rich source of essential oil and phenolics. The ETHOS X extraction system is known as a commercial microwave-assisted extraction (MAE) system for extracting bioactive compounds from plant materials. This study investigated the influence of soaking time, radiation time, microwave power, and sample to solvent ratio on the extraction efficiency of polyphenols and antioxidant properties from lemon-scented tea tree leaves and optimized the extraction conditions using response surface methodology (RSM). The effectiveness of ETHOS X was further compared with ultrasound-assisted extraction (UAE) and shaking water bath (SWB) techniques. The results revealed that soaking time did not significantly affect the recovery of phenolics from the leaves (p > 0.05). Thus, soaking is not required for the ETHOS X extraction of polyphenols from LSTT leaves. RSM was successfully applied to explore the impact of ETHOS X extraction conditions and optimize the extraction conditions. Radiation time significantly affects the recovery yield of phenolics (p < 0.05) positively, whereas irradiation power and sample to solvent ratio adversely influenced the extraction yields of phenolics. The optimal ETHOS X extraction conditions were: radiation time of 60 min, irradiation power of 600 W, and sample to solvent ratio of 2 g/100 mL. Under these conditions, 119.21 ± 7.09 mg of phenolic, 85.31 ± 4.55 mg of flavonoids, and 137.51 ± 12.52 mg of proanthocyanidins can be extracted from a gram of dried LSTT leaves. In comparison with UAE and SWB, ETHOS X is not more effective for the extraction of phenolics than UAE and SWB. However, this technique can save half of the solvent volume compared to UAE and SWB techniques.

“…Преимущества заключаются в том, что большой объем препарата может быть извлечен малым количеством растворителя, применим к термостойким растительным материалам, не требуется фильтрация. В числе недостатков невозможность регулярного встряхивания; не совместимость с термолабильными материалами [3][4][5].…”

The development of extraction techniques of medical plants aims to maximize the bioactive compounds production. Тechnologies in this area of industry have not high enough еfficiency factor. In some cases, it reaches only 40-50 %. Therefore, development of new methods to effectively extract different compounds from plant material and their input into large-scale industry is of great importance. The goal is to determine an effective and suitable technology for extracting bioactive compounds from medical plant. This is a narrative review paper which focuses on different extraction methods of medical plant. To find relevant articles for this narrative review, 73 articles were reviewed. Of these, 14 irrelevant documents were discarded. This review analyses various extraction processes to guide the selection of suitable methods for various types of medical plants and applications. This is done by outlining traditional and modern methods of extraction techniques, exploring the importance of solvents for extraction, and comparing novel and alternative methods of extraction. In conclusion, based on the current knowledge, solvent extraction is the most common method for medical plants extraction. Enzymatic hydrolysis and supercritical extraction are advanced techniques with high yield of compounds. However, more research is needed for some modern extraction methods
