Abstract:

From pollen grains of Typha davidiana, T. latifolia, T. angustata the same eight

flavonoids have been isolated. They are identified as naringenin I, isorhamnetin II, quercetin

III, isorhamnetin-3-O-(2^G-α-L-rhamnopyranosyl)-rutioside IV, quercetin-3-O-(2^G-α-L-rhamnopy-

ranosyl)-rutinosida, V, isorhamnetio-3-O-rutinoside VI, isorhamnetino-3-O-neohesperidoside VII,

kampferol-3-O-neohesperidoside VIII. Flavonoids of pollen grains of five species of Typha, in-

cluding the above three species, were analysed by TLC with the result showing that the consti-

tuents in the pollen grains of the five species are very similar.

The chemical comparison among Typha and Sparganium and 16 possibly related families

shows that Typha is different from Pandanaceae or Pandanales and is similar to Restionaceae,

Flagellariaceae, Juncaceae and Cyperaceae in some respects. Typha and Sparganium are very

similar in many respects, and they could be treated in the same family, Typhaceae, which merit

the rank of order, Typhales.

Key words: Typha L, Flavonoids, Flavonol glycosides, Chemosystematics
