Peroxidation assay because it has been reported that lipid peroxides on hair follicles led to the early onset on the catagen which would lead to the hair loss [10]. Among five E. debile extracts, EA possessed the highest lipid peroxidation inhibition (57.2 0.four ). EA also showed favorable antioxidant results in other assay using the EC1 of 115.7 39.9 mM FeSO4 /g and TEAC of 7.two three.three mM Trolox/g. EA contained high amount of total phenolic content material (30.6 1.two mg GA/g) which was more abundant than CE (26.6 1.7 mg GA/g). The explanation might be from the removal of non-polar compounds by the fractionated extraction approach considering that HE which was the nonpolar extract contained very little quantity of the phenolic content (5.six 1.1 mg GA/g). The results had been within a excellent agreement with the previous study which reported that a higher and important antioxidant Noggin Protein web activity was detected inside the ethyl Animal-Free BDNF Protein Biological Activity acetate fraction when comparing to an aqueous extract (infusion) plus the important phenolic compounds accountable for the antioxidant activity had been flavan-3-ol, kaempferol, and many phenolic acid derivatives [44]. Moreover, yet another study reported that quercetin, a flavonoid antioxidant, was isolated from ethyl acetate extract in the aerial stems of E. debile [32]. Thus, quercetin will be among the compounds that was accountable for the high antioxidant activity of E. debile extracts given that it really is able to scavenge highlyNutrients 2017, 9,15 ofreactive species for instance peroxynitrite along with the hydroxyl radical [45]. In conclusion, EA was the most desirable extract applied for anti-hair loss since it showed the highest inhibitory activity against 5-reductase, IL-6 secretion, and lipid peroxidation. Besides, the earlier research happen to be reported that fraction ethyl acetate extract of E. debile contained numerous phytosterols, flavonoids, and phenolic compounds which will be helpful for well being [32,46]. Additionally, EA was not toxic towards the human dermal papilla cells and triggered no irritation on HET-CAM. For that reason, EA may possibly be used as functional meals and nutraceuticals components for anti-hair loss. five. Conclusions The present study demonstrated the inhibitory activity against 5-reductase, IL-6 secretion, and oxidation process of E. debile extract. EA exerted the highest inhibition on 5-reductase (26.6 3.three ) and lipid peroxidation (57.2 0.4 ), whereas ET possessed the highest antioxidant activity (EC1 = 289.1 26.4 mM FeSO4 /g, TEAC = 156.6 34.six mM Trolox/g, and DPPH inhibition = 20.0 six.0 ), which was associated to its highest amount of phenolic content (68.eight six.7 mg GA/g). The results noted that EA was extremely protected because it showed no cytotoxicity on dermal papilla cell line and no irritation on chorioallantoic membrane of hen’s eggs. As a result, EA may possibly be an appealing ingredient for functional meals and nutraceuticals for anti-hair loss because of the highest inhibitory activity against 5-reductase, IL-6 secretion, and lipid peroxidation inhibition. However, the pharmacokinetic study of E. debile extract would be suggested for the additional study.Acknowledgments: The authors are grateful for economic help received from Highland Analysis and Improvement Institute (Public Organization) (grant quantity 4/2560); Chiang Mai University (grant for new researchers 2016); and ASEAN-European Academic University Network (ASEA-UNINET) (grant number ICM-2015-01430).
