Abstract
Conventional extraction methods have many limitations and drawbacks, including prolonged extraction time, present safety concerns, and environmental risks with low-quality extracts. We report the use of ultrasonic (UAE) and microwave (MAE) assisted technologies as techniques for improving the extraction of pharmaceutically active materials from Opuntia ficus-indica (OFI), a species of prickly pear. The pulp and peel of the plant fruit were used, and the total phenolic and flavonoid contents were evaluated. Antioxidant assay (DPPH) was employed to prescreen different extracts. The Hepa1c1c7 model was used for testing the induction of chemopreventive marker protein NAD (P) H-quinone oxidoreductase 1 (NQO1). The in vitro anti-inflammatory activity was performed on RAW 264.7 macrophage model induced for nitric oxide (NO) release in the presence of lipopolysaccharide. In vivo study included testing the therapeutic potential of some extracts on carrageenan-induced paw edema in adult rats. Our data showed that fruit peels had the highest contents of phenolic and flavonoid compounds of OFI extracted using microwave-assisted extraction (MAE) at 800 W power for 5 min extraction time (EXM1) with a percentage increase of 74.1% and 115.3%, respectively when compared to conventional maceration. DPPH prescreen revealed the potency of the EXM1 among other tested extracts, recording EC50 148 µg/mL. Although in vitro chemopreventive as an anti-inflammatory model revealed no activity on (NQO1) induction of EXM1, the in vivo model gave positive results. The edema size reduction percentage of EXM1 was 104% after 4 hours. Anti-inflammatory markers indicated that EXM1 inhibited COX-2, IL-6, TNF-α, and TGF-β1 more significantly than indomethacin and conventional extraction methods. The data obtained confirmed the beneficial value of MAE and UAE technologies for the extraction of the active material of (OFI).
