Besides the action on bacteria, bamboo vinegar had antioxidant
ability due to more than 200 organic compounds present,
such as phenolic compounds, alkone compounds, alcohol
compounds, aldehyde compounds, and others (Ikimoto and
Ikeshima, 2000; Nomura, 2004; Uchimura et al., 2000). Main
kinds of phenolic compounds were also found in bamboo vinegar
extracted with ethyl acetate by GC–MS analysis in this
study.
