OBJECTIVE

To study the chemical constituents of Bletilla striata.

METHODS

The constituents were separated and purified by column chromatography with silica gel, and identified by NMR, MS and physical data.

RESULTS

Three compounds were isolated and identified as hexacosanoic alcohol 3-(4-hydroxy-3-methoxybenzol)-trans-acryliceylenate(1), physcion(2) and cyclobalanol(3).

CONCLUSIONS

Compound 1 was a new compound and compound 3 was isolated from this plant for the first time.
