Abstract:

Catharanthus roseus (L.) G. Don cell suspension cultures were used to transform 3b-hydroxyandrost-5-en-17-one, the products were isolated by chromatographic methods. Their structures were established by means of NMR and MS spectral analyses. Nine metabolites were respectively elucidated as: androst-4-ene-3,17-dione (Ⅰ), 6a-hydroxyandrost-4-ene-3,17-dione (Ⅱ), 6a,17b-dihydroxyandrost-4-en-3-one (Ⅲ), 6b-hydroxyandrost-4-ene-3,17-dione (Ⅳ), 17b-hydroxyandrost-4-en-3-one (Ⅴ), 15a,17b-dihydroxyandrost-4-en-3-one (Ⅵ), 15b,17b-dihydroxyandrost-4-en-3-one (Ⅶ), 14a-hydroxyandrost-4-ene-3,17-dione (Ⅷ), 17b-hydroxyandrost-4-ene-3,16-dione (Ⅸ). It is the first time to obtain the above compounds by biotransformation with Catharanthus roseus cell cultures.

Key words: Catharanthus roseus, cell suspension cultures, biotransformation, 3b-hydroxyandrost-5-en-17-one
