“…Well linear correlation was detected in DPPH assay with the R 2 of 0.8953. The results were in line with a previous study that reported that DPPH • was a stable free radical, which could be scavenged by a free radical species or an antioxidant, especially purified phenolic compounds [48,55]. However, no correlation was detected in FRAP, ABTS, and FTC assay with the R 2 less than 0.3.…”

“…Therefore, the antioxidant of CE and CA were more pronounced. Additionally, the results were in a good agreement with the previous study of Ling and Palanisamy (2012), who reported that ethanolic extract of Arumanis Mangoe possessed higher ABTS •+ scavenging ability than the water extract, and the study of Shalaby and Shanab (2013), who reported that Spirulina platensis showed higher antiradical and antioxidant activity (99.55%) with ABTS and absolute methanol extract, while the water extract presented slightly lower activities (95.3%) when tested with DPPH hydrogen reacting radicals [47,48]. However, cordycepin possessed no ABTS •+ scavenging ability with the TEAC value about zero (0.0 ± 0.5).…”

This study aimed to develop nanoemulsions for enhancing chemical stability and dermal delivery of Cordyceps militaris extracts. C. militaris was extracted by maceration and infusion. The extracts were investigated for cordycepin, phenolic, and flavonoid content. The antioxidant activity was investigated by in vitro spectrophotometric methods. The irritation profile was investigated by hen’s egg-chorioallantoic membrane test. Nanoemulsions were developed using high-pressure homogenizer. C. militaris extract was incorporated into the nanoemulsion and investigated for safety, release profile, permeation, and skin retention. The results demonstrated that water extract (CW) contained the significantly highest content of cordycepin, phenolics, and flavonoids, which were responsible for antioxidant activity. CW was the most potent antioxidant. CW possessed comparable 2,2′-diphenyl-1-picrylhydrazyl radical scavenging activity and lipid peroxidation inhibition to l-ascorbic acid (96.9 ± 3.1%) and alpha-tocopherol (87.2 ± 1.0%). Consequently, ten mg/mL of CW was incorporated into nanoemulsions composing of sugar squalene, Tween® 85, and deionized water. Nanoemulsion, which had the smallest internal droplet size (157.1 ± 2.6 nm), enhanced the stability of CW, had no cytotoxicity effect and no skin irritation, released the most CW (0.9 ± 0.0% w/w after 24 h), and delivered the highest CW into the skin layer (33.5 ± 0.7% w/w). Therefore, nanoemulsion was suggested for enhancing the stability and dermal delivery of CW.

Malaysian is among the most diverse plant resource country in the world especially with its richesnest flora and fauna. It has about 12,000 species of flowering plants of which about 1,300 species were said to be medicinal plant and have been investigated for their therapeutic potential. Spies have been known to be a valuable source of bioactive compound which are being used to treat various diseases and improved health for a thousand years ago. The beneficial health effects of medicinal plants come from polyphenols group which is often attributed to their potent antioxidant activities. This paper reviews the antioxidant potential of selected plants from Malaysia as Persicaria hydropiper, Cosmos caudatus and Melicopeptelefolia based on reported from several researchers.
