- Abstract: This paper is aimed to study plant biomass and active compounds of Scutellaria baicalensis germchit in different five stages (from germination to transplant). The length of shoot and root, the diameter and the weight of root were determined. HPLC method was used to determine the content of active compounds (baicalin, scutellarin, wogonoside, baicalein, wogonin). According to the results, various biological indicators increased with the germination of seedling. However, the drying rate of the root declined to 27.96% from 32.90%. The contents of scutellarin and baicalein increased firstly, and then decreased. The maximums of them were 3.22,3.89 mg•g⁻¹ while the data of shoot/root was 0.35. The maximums of the contents of baicalin and wogonoside were 107.39,16.11 mg•g⁻¹ while the data of shoot/root was 0.23 and 0.06. The contents of wogonin gradually increased to the maximum of 0.88 mg•g⁻¹ while the data of shoot/root was 0.50. In conclusion, the contents of baicalin, scutellarin, wogonoside, baicalein and wogonin reached or approached the maximum at germination stage while the data of shoot/root was 0.35. The rate of shoot and root can be used as a judging index of active compounds for S. baicalensis germchit.
