OBJECTIVE
To investigate the chemical constituents with anti-hypoxia activity from Saussurea involucrata.
METHODS
The chemical constituents, isolated and purified by column chromatography from Saussurea involucrata, were identified by several spectroscopic methods. The anti-hypoxic activities of these compounds were examined using the normobaric hypoxic model of mice.
RESULTS
Twelve compounds were isolated from petroleum ether extract of Saussurea involucrata and identified as n-octacosane (1), 1-undecanol (2), heptadecan-l-ol(3), heptacosan-1-ol(4), myristicin (5), apiol(6), β-sitosterol(7), lupeol(8), moslosooflavone (9), mosloflavone (10), negletein(11), and 5, 6-dihydroxy-7, 8-dimethoxyflavone(12).
CONCLUSIONS
All compounds except 7 and 8 are isolated from this plant for the first time. Compound 1, 5 and 8 - 12 can significantly prolong the survival time of hypoxic mice.
