The new flavone di-C-glycoside, tricetin 6,8-di-C-alpha-L-arabinopyran
oside and the known tricetin 6,8-di-C-beta-D-glucopyranoside and trice
tin eta-D-glucopyranosyl-8-C-alpha-L-arabinopyranoside were identified
from Plagiochila jamesonii. From Plagiochasma rupestre the new luteol
in 6,8-di-C-alpha-L-arabinopyranoside was isolated together with five
partly characterized luteolin di-C-pentosides.
