RESUMO
The butanol extract part was extracted and isolated with water, alcohol and different organic solvents from Abrus mollis leaves. 6 compounds were isolated and purified using various column chromatographies and identified with the spectral techniques such as UV, MS, TLC, HPLC and NMR. The structures of 6 compounds were trigonelline (1), praline (2), alanine anhydride (3), (Z)-N-(4-hydroxycinnamoyl)tyrosine (4), (E)-N-(4-hydroxycinnamoyl)tyrosine (5), and abrusamide C (6). Compound 6 is a new compound, and compounds 1-4 were isolated from the plant for the first time.

OBJECTIVE: To analyze and compare the composition of Radix Salviae Miltiorrhizae from different habitats by HPLC and TLC. METHODS: The fingerprints of Radix Salviae Miltiorrhizae were detected by HPLC and TLC. RESULTS: Radix Salviae Miltiorrhiza collected from different habitats showed diverse fingerprints of component. The content of tanshinone II A of Radix Salviae Miltiorrhizae in Shandong was the highest, which is 3.5 times higher than Shangluo of Shanxi province. CONCLUSION: The character of two analytical mehods with fingerprint of component is significant, simplicity, and reproducibility is great. The methods can be used to select Radix Salviae Miltiorrhizae for clinical and resarch institution.
