Pyrogallol

Faʻamatalaga puʻupuʻu:

Folasaga: Pyrogallol

o se vailaʻau vailaʻau ma vailaʻau mata mea ma tele faʻaoga. Na gaosia i le faiga na muamua saunia e Scheele (1786): faʻavevela gallic acid. Taimi nei gallic acid e maua mai le tannin. O le faʻamafanafana e faʻaosofia ai le decarboxylation 。E tele na te faʻaaogaina i vailaʻau o vailaʻau, vali, meaʻai, vailaʻau ma vailaʻau eletise.
