“…Further, initial soaking for a fixed time followed by extraction or homogenization prior to extraction did not enhance extraction efficiency significantly. Better extraction of phenolic components from Tagetes erecta was reported by Kazibwe, Kim, Chun, & Gopal (2017 ), where hot water extraction, waterbath sonication and ultrafast ultrasonication were compared. Ultrasonic cleaning bath and probe system can be efficient source of extraction for better yield.…”

“…For instance, to inhibit Staphylococcus aureus , a US treatment of 187 min and 150 W, 20 kHz is required [ 111 ]. Also, Kazibwe, Kim, Chun and Gopal [ 112 ] studied the US (20, 60 kHz; 200, 300 W; 2 min) assisted extraction effects of Tagetes erecta herb on their antimicrobial activity. They subjected two different bacterial strains to these extracts (Streptococcus mutans and Pseudomonas aeruginosa).…”

“…This study suggested that in terms of yield, the efficacy of the US will depend on the plant/ material used, and thus optimization reported in the literature cannot be extrapolated to other materials. In the study of Carbone and colleagues [ 112 ], it is important to highlight that US treatment did not use high power like MW (2.45 GHz, 210 °C, 2.4 × 10 6 Pa), which could have a negative effect on the phytochemicals structure and function. In terms of selectivity, treating rosemary leaves with US (19.5 kHz,140 W) showed remarkably high ( p < 0.05) recovery of carnosic acid and rosmarinic acid contents (13%, 6.8% of the dried extract) compared to MW (100 °C, 20 bar) [ 32 ].…”

Highlights
Ultrasound enhances the phenolic compounds in extracted herbal oils by 44%.
US (25–50 kHz) increases the yields of polyphenols, carotenoids, and flavonoids.
Radicals generated by US have positive and negative effects on enzymes.
US improves the efficiency of herbal extracts in Nanotechnology applications.
Acoustic-based biosensors could be used for chemical imaging of herbal tissues.
“…The benefit of antimicrobial activity is one of the most proven targets by several authors through studies on the antifungal capacity of plants from this genus [ 202 ].…”
Section: Antifungal Activity Of Plants From the
Tagetesmentioning
Tagetes (marigold) is native to America, and its cultivation currently extends to other countries in Africa, Asia, and Europe. Many species of this genus, such as T. minuta, T. erecta, T. patula, and T. tenuifolia, are cultivated as ornamental plants and studied for their medicinal properties on the basis of their use in folk medicine. Different parts of the Tagetes species are used as remedies to treat various health problems, including dental, stomach, intestinal, emotional, and nervous disorders, as well as muscular pain, across the world. Furthermore, these plants are studied in the field of agriculture for their fungicidal, bactericidal, and insecticidal activities. The phytochemical composition of the extracts of different Tagetes species parts are reported in this work. These compounds exhibit antioxidant, antiinflammatory, and enzyme inhibitory properties. Cultivation and the factors affecting the chemical composition of Tagetes species are also covered. In the current work, available literature on Tagetes species in traditional medicine, their application as a food preservative, and their antimicrobial activities are reviewed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
