Abstract

The metabolic capability of the cultured cells of peppermint was tested with whole intact cells by feeding appropriate exogenous substrates to the suspension cultures. Conversion of (-)-limonene into any other monoterpenes was not observed with the suspension cultures. (+)-Pulegone was converted into (+)-isomenthone and (-)-menthone, and (-)-menthone into (-)-menthol. The experiments confirmed that the suspension retained most of the menthol biosynthesis pathway in the cell except for a few loci. (-)-Isopiperitenone was transformed into (+)-pulegone, piperitenone, (-)-7-hydroxyisopiperitenone and two unidentified products.

박하(Mentha piperita) 세포현탁배양에(-)-menthol 생합성 중간체를 투여하여 배양된 세포의 대사경로를 연구하였다. (-)-Limonene을 투여 하였을 때 이는 다른 대사물로 변환되지 않는 것으로 관찰 되었다. (+)-Pulegone은 (+)-isomenthone 및 (-)-menthone으로 변환되었으며, (-)-menthone은 (-)-menthol로 변환되었다. 이 실험은 현탁배양세포가 대부분의 생합성 활성을 유지하고 있으며 (-)-limonene hydroxylase의 활성이 제한적임을 보여 주었다. (-)-Isopiperitenone을 투여하였을 때는 (+)-pulegone, piperitenone, (-)-7-hydroxyisopiperitenone, (R)- 및 (S)-6-hydroxyisopiperitenone이 생성되었다.
