This study is the first report on antioxidant activities and chemical composition of S. cambodianum Baill. ethanolic leaf extract. The results showed that ethanolic extract had potent in vitro antioxidant activities in DPPH, ABTS•+ assays (the low concentrations of IC50 were 19.51 ± 0.78 μg/mL and 4.89 ± 0.07 μg/mL, respectively), and in RP, TAC methods (the Abs0.5 were 20.80 ± 0.26 μg/mL and 36.15 ± 1.03 μg/mL).

In recent studies, Azadirachta indica, Andrographis paniculate, Ocimum canum and Pongamia pinnata, which are inhibitors derived from plants have been used to provide corrosion inhibition effect. The inhibitive ability of C. albidum in several corrosive media reported by researchers has prompted its examination in 1 M H2SO4 solution using polarization techniques, gravimetric and gasometric in this present work.

Zoanthid is a potential natural resource with many biological activities, such as antioxidant, antiviral, antiinflammatory, and cytotoxic activity. Therefore, this study aimed to evaluate the antioxidant activity of 70% ethanol crude extract and dichloromethane fraction from Zoanthus vietnamensis. The total polyphenol content of ethanol and dichloromethane extracts were 19.36 ± 1.37 and 24.95 ± 0.63 mg GAE/g extract, respectively.

This study aimed to extract and evaluate some properties and the capability of phenolic components from shallot (Allium ascalonicum L.) peels for usage as fish preservative. It was found that shallot peels extracted twice with 70 % ethanol solvent, within 60 minutes, at 60 oC and the ratio of solid/liquid 1/20 (g/mL) gave highest polyphenol and flavonoid yields. Total polyphenol content and total flavonoid content of the extract were 224.34±5.66 mg GAE/g DW and 255.11±4.35 mg QE/g DW, respectively.

The flowers of Hylocereus undatus (Haw.) Britton & Rose have been reported in vitro antioxidant and tyrosinase inhibitory activities. This study screened preliminarily the triterpenoid constituents and evaluated in vitro tyrosinase inhibitory activity of H. undatus flowers. H. undatus flowers were harvested from Binh Thuan Province, Vietnam at four different flowering stages, and their five separated parts (stamen, pistil, petals, ovary, and sepals) were extracted with ethanol.
