“…In the samples of fresh peppermint leaves, a high content of total phenols (1 722.25 mg l -1 ) was determined, which is a slightly lower value, compared with the total phenol content of fresh lemon balm leaves. The results obtained are consistent with other literature data, which emphasize a significantly high phenol content of peppermint leaves (Lv et al, 2012;Kapp et al, 2013;Riachi and De Maria, 2015). During the 24 h of classical extraction of fresh peppermint leaves in water, the total phenol content was 1 472.49 mg l -1 , which is an about 15% lower value in comparison with the total phenol content identified in fresh leaves.…”

“…The antioxidant activity of fresh peppermint leaves was lower than the antioxidant values determined for fresh lemon balm leaves, which was expected, since fresh lemon balm leaves had higher total phenol content. Oh et al (2013) and Riachi and De Maria (2015) emphasize the very high antioxidant capacity of aqueous peppermint solutions, comparing different methods for testing the antioxidant activity (FRAP, ORAC, ABTS, DPPH).…”

A b s t r a c t. The aim of this study was to investigate the influence of conventional and ultrasound-assisted extraction (frequency, time, temperature) on the content of bioactive compounds as well as on the antioxidant activity of aqueous extracts from fresh lemon balm and peppermint leaves. Total phenols, flavonoids, non-flavonoids, total chlorophylls, total carotenoids, and radical scavenging capacity were determined. Moreover, the relationship between bioactive compounds and antioxidant capacity was studied by linear regression. A significant increase in all studied bioactive compounds during ultrasonic extraction for 5 to 20 min was found. With the classical extraction method, the highest amounts of total phenols, flavonoids, and antioxidant activity were determined, and the maximum amounts of total chlorophylls and carotenoids were determined during 20 min ultrasonic extraction. The correlation analysis revealed a strong, positive relationship between antioxidant activity and total phenolic compounds.

“…Eriocitrin, a flavanone glycoside, was a minor compound, while chlorogenic acid was found only in trace amounts. These findings agreed in part with reports described elsewhere (Fecka and Turek, 2007;Farnad et al, 2014;Riachi and De Maria, 2015). Individual phenolic composition from the CPS tisanes showed a great variation.…”

Essential oils and infusions from commercial peppermint sachets (CPS), and noncommercial genuine peppermint (NCP) and cornmint (NCC) samples were analyzed by GC/MS and LC/MS. Minimum inhibitory concentration (MIC) of mint oils against Fusarium moniliforme, Aspergillus niger and Aspergillus fumigates was determined. Antioxidant potential was monitored by total phenolic content (TPC), 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical and soybean oil oxidation tests. CPS and NCC oils had lower menthofuran content than NCP. Mint oils did not show a uniform standard of antifungal activity and they had the modest reducing ability. CPS and NCC infusions showed higher IC50 and lower TPC than NCP ones. In the soybean oxidation test, mint oils presented prooxidant behavior. CPS infusions showed antioxidant potential significantly (P<0.05, Tukey) lower than that from NCC and NCP infusions. NCP infusions were more efficient in delaying propagation reaction than NCC ones. This may be attributed to higher amount of rosmarinic acid and hesperidin in NCP.

Biopolymeric chitosan is considered a promising encapsulating agent for textile applications due to its biocompatibility, lack of toxicity, antibacterial activity, high availability, and low cost. After cellulose, it is nature's most important organic compound. Also, chitosan has unique chemical properties due to its cationic charge in solution. Microencapsulation technologies play an important role in protecting the trapped material and in the durability of the effect, controlling the release rate. The application of chitosan microcapsules in textiles follows the current interest of industries in functionalization technologies that give different properties to products, such as aroma finish, insect repellency, antimicrobial activity, and thermal comfort. In this sense, methods of coacervation, ionic gelation, and LBL are presented for the production of chitosan-based microcapsules and methods of textile finishing that incorporate them are presented, bath exhaustion, filling, dry drying cure, spraying, immersion, and grafting chemical. Finally, current trends in the textile market are identified and guidance on future developments.
