Studies on the Constituents of Typha L.—IV. A Preliminary Study of Chemosystematics of Typha L.

香蒲属的成分研究——IV.香蒲属化学和系统学的研究


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-(2G-α-L-rhamnopyranosyl)-rutioside IV, quercetin-3-O-(2G-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.
