Manuscripts in most areas of science are welcomed except in areas such as agriculture, engineering and medical science which are outside the scope of the Journal. Currently, we focus on manuscripts in biology, chemistry, physics, materials science and environmental science. Papers in mathematics statistics and computer science are also included but should be of an applied nature rather than purely theoretical. Manuscripts describing experiments on humans or animals are required to provide proof that all experiments have been carried out according to the ethical regulations of the respective institutional and/or governmental authorities and this should be clearly stated in the manuscript itself. The Editor reserves the right to reject manuscripts that fail to do so. Hoya kerrii Craib (HK) has long been used as folk medicines for curing inflammatory-related diseases. This study aimed to investigate the phytochemical constituents, antioxidant and anti-inflammatory effects of 95% ethanol extract of HK (HKE). The high-performance liquid chromatography diode array detection mass spectrometry (HPLC-DAD-MS) analyzes of polyphenolic composition indicated the presence of gallic acid, catechin, tannic acid, isoquercetin, kaempferol, quercetin, rutin, genistein, daidzein, genistin and daidzin in HKE as bioactive compounds. The extract exhibited antioxidant properties based on 2,2-diphenyl-1-picryl-hydrazyl (DPPH) radical scavenging activity and ferric reducing antioxidant power (FRAP) assays. HKE also alleviated the tert-butyl hydroperoxide (tBuOOH)-induced reactive oxygen species (ROS) generation in RAW264.7 cells as measured by using 2’,7’-dichlorofluorescin-diacetate (DCFH-DA) assay. HKE suppressed LPS plus IFN-γ-induced nitric oxide (NO) production in RAW264.7 cells as determined by using Griess reagent. HKE exhibited the immunomodulatory effects by suppressing the secretion of pro-inflammatory cytokines TNF-α and IL-6 from RAW264.7 cells activated by LPS plus IFN-γ which was performed by enzyme-linked immunosorbent assay (ELISA). Collectively, these results suggest that HK may be applied as a promising antioxidant and anti-inflammatory natural agent through modulation of inflammatory mediators NO and cytokines such as IL-6 and TNF-α. 2020-10-08T08:36:16Z 2020-10-08T08:36:16Z 2020 Chiang Mai Journal of Science 47,5 (Sep 2020), p.912-925 2465-3845 https://epg.science.cmu.ac.th/ejournal/dl.php?journal_id=11191 http://cmuir.cmu.ac.th/jspui/handle/6653943832/69899 Eng Faculty of Science, Chiang Mai University |
