Article Synopsis
- The study examined how different plant densities affect the root yield and biomarker content of Salvia miltiorrhiza Bunge, a medicinal herb, through a field trial with six density variations.
- Significant variations in yields and biomarker contents were found, with best root yields per plant at densities of 45×30 cm or 45×40 cm, and optimal biomarker production at 30×30 cm.
- The findings indicate that adjusting plant density can enhance the quality and quantity of both root yields and important medicinal compounds, providing insights for improved cultivation practices.
Salvia miltiorrhiza f. alba (Baihua Danshen) is a Chinese medicinal herb commonly used for treating cardiovascular disease. It has been grown in Australia, although the quality of its main medicinal part (dried root) has not been assessed.

Cryptotanshinone, tanshinone I, tanshinone IIA, and salvianolic acid B were quantitatively determined by reversed-phase (RP) HPLC. Similar accumulation patterns were observed for the three tanshinones throughout the trial period, although roots harvested in the first year was found to contain relatively higher contents of these compounds.

In the present work, we studied cultivar variations of Australian-grown Danshen in order to select optimal cultivars for local herbal production. Root yields of seven cultivars, V1-V7, were monitored in a one-year field trial, and bioactive markers, including cryptotanshinone, tanshinone I, tanshinone IIA, and salvianolic acid B, were quantitatively determined using a validated RP-HPLC method.
