Article Synopsis
- The study analyzed the absorption spectrum of a red compound formed from Fe2+ and 1,10-phenanthroline, as well as the antioxidant potential of TBHQ and bamboo leaf extract in scavenging hydroxyl free radicals.
- The key findings revealed that the optimal wavelength for measuring bamboo leaf extract’s scavenging ability is 509.1 nm, with IC50 values indicating the concentration required to scavenge half of the hydroxyl free radicals.
- The IC50 values for the antioxidants tested were TBHQ at 0.040 and varying concentrations of bamboo leaf extract (M20, M40, M60) ranging from 0.323 to 0.378, supporting

A new flavonoid, 5,7,3'-trihydroxy-6-C-beta-D-digitoxopyranosyl-4'-O-beta-D-glucopyranosyl flavonoside (1), along with four known flavonoids 5,7,4'-trihydroxy-3',5'-dimethoxy flavone (2), 5,3',4'-trihydroxy-7-O-beta-D-glucopyranosyl flavonoside (3), 5,4'-dihydroxy-3',5'-dimethoxy-7-O-beta-D-glucopyranosyl flavonoside (4), 5,3',4'-trihydroxy-6-C-[beta-D-glucopyranosyl-(1 --> 6)]-beta-D-glucopyranosyl flavonoside (5) were isolated from 95% EtOH extract of the leaves of Pleioblastus argenteastriatus. Their structures were determined on the basis of spectroscopic techniques and chemical methods.

By studying absorption spectrum, oxidation velocity of pyrogallic acid reaction system, the effect of pyrogallic acid concentration and buffer pH value on the scavenging rate for superoxide anion free radical coming from reaction system was investigated, and some results were obtained as follows, the wavelength used for the pyrogallic acid reaction system was determined by spectrophotometric method: 319.5 nm. Some parameters of the reaction system were determined as follows: reaction volume: 10 mL, reaction time: 9 min, volume of pyrogallic acid (3 mmol x L(-1)): 0.
