title: Tanshinone production in roots of micropropagated Salvia przewalskii Maxim.
abstract: Production of tanshinones (tanshinone I and IIA) was determined in roots of Salvia przewalskii micropropagated plants. It was found that the total tanshinone content (tashinone I and tashinone IIA) was dependent on the age of the analyzed plants. The roots of 2-year-old in vitro regenerated plants at flowering stage produced highest tanshinone levels (3.8 mg/g dry weight of tanshinone I and 7.6 mg/g dry weight of tanshinone IIA).
