• Seven new phenylhexanoids, ( )-(+)-3,4-dihydroxy-11-methoxyphenylhex-9-one ( ), ( ) 3,4-dihydroxy-phenylhex-10-en-9-one ( ), ( )-4-hydroxyphenylhex-10-en-9-one ( ), ( )-(-)-3,4,11-trihydroxyphenylhex-9-one 11- - -d-glucopyranoside ( ), ( )-(-)-4,11-dihydroxyphenylhex-9-one 11- - -d-glucopyranoside ( ), phenylhex-4,9,11-triol 11- - -d-glucopyranoside ( ), and 9- -acetyl-phenylhex-4,9,11-triol 11- - -d-glucopyranoside ( ), were isolated and identified from Tibetan medicine var. . The antioxidant activities of these compounds were evaluated using the DPPH and ABTS radical scavenging experiments. In the ABTS experiment, compounds (IC 13.99 ± 2.53 μM) and (IC 13.11 ± 0.94 μM) exhibited significantly better antioxidant activity than L-ascorbic acid (IC 23.51 ± 0.44 μM).
