ABSTRACT

Objective:

Nitrogen is an important element affecting the accumulation of effective components in Chinese medicinal materials. The purpose of this study was to investigate effects of different nitrogen sources on the growth and active components accumulation of hairy roots of Salvia miltiorrhiza and Salvia castanea f. tomentosa.

Methods:

The hairy roots of S. miltiorrhiza and S. castanea f. tomentosa were treated with ammonium nitrate, hydrolyzed milk protein, peptone, beef extract, casein and yeast extract, respectively. The growth of hairy roots and the accumulation of active components were analyzed.

Results:

Ammonium nitrate was the most beneficial to the growth of the two kinds of hairy roots. Hydrolyzed milk protein significantly promoted the accumulation of salvianolic acids, compared with ammonium nitrate, the contents of rosmarinic acid and salvianolic acid B in S. miltiorrhiza were respectively increased by 2.94 times and 3.27 times, and the contents of rosmarinic acid and salvianolic acid B in S. castanea f. tomentosa were respectively increased by 13.74 times and 2.01 times. Yeast extract had the most significant effect on the accumulation of dihydrotanshinone I and cryptotanshinone in two kinds of hairy roots. Hydrolyzed milk protein significantly promoted the accumulation of tanshinone IIA in the hairy roots of S. miltiorrhiza, while beef extract had the most significant effect on the accumulation of tanshinone IIA in S. castanea f. tomentosa.

Conclusion:

Ammonium nitrate was the best nitrogen source for the growth of two kinds of hairy roots, and hydrolyzed milk protein was the best nitrogen source for salvianolic acids accumulation. The effects of different nitrogen sources on four kinds of tanshinones were different, and the responses of S. miltiorrhiza and S. castanea f. tomentosa to different nitrogen sources were also different. This study not only has certain guiding significance for large-scale cultivation of hairy roots of S. miltiorrhiza and industrialized production of active components, but also provides a reference for the development and utilization of S. castanea f. tomentosa resources.
