## Abstract A modified acetyl bromide procedure is proposed for the spectrophotometric determination of lignin in herbaceous plants. The digestion with 25 % acetyl bromide (AcBr) in acetic acid at 70ยฐC is improved by including 4 % perchloric acid in the digesting solutions. This allows for more rap
