Objective:
To study the chemical constituents from the roots of Ficus hirta.
Method:
Compounds were isolated by chromatographic techniques on silica gel and HP-20 resin columns. Their structures were elucidated by chemical and spectroscopic methods.
Result:
Ten compounds were identified as beta-sitosterol (1), stigmasterol (2), psoralene (3), 3beta-hydroxy-stigmast-5-en-7-one (4), 5-hydroxy-4', 6, 7, 8-tetramethoxy flavone (5), 4', 5, 6, 7, 8-pentamethoxy flavone (6), 4', 5, 7-trihydroxy-flavone (7), 3beta-acetoxy-beta-amyrin (8), 3beta-acetoxy-alpha-amyrin (9) and hesperidin (10).
Conclusion:
The compounds 4, 5, 6 were obtained from this genus for the first time, and all the compounds were obtained from this plant for the first time.
