4.3 PLANT RESOURCES
HA has been obtained from H. serrata,
1
Phlegmariurus fordii (Baker) Ching,
2
L. selago,
27
L. serratum (Thunb.) var. Longipetiolatum Spring,
28
and Lycopodium
varium.

These clubmoss plants belong to the family of Huperziaceae or Lyco-
podiaceae of Lycopodiales order from the viewpoint of plant taxonomy. We
conducted a large-scale plant investigation for the HA source in China.
31
A total
of 67 species, 11 varieties, and 2 forma were collected from 19 provinces in
China, and the sources of the Huperzia, Phlegmariurus, and Lycopodium species
were also investigated in those provinces. The examination of the chemical consti-
tuent demonstrated that HA was mainly present in the Huperziaceae family (con-
sisting of genus Huperzia and genus Phlegmariurus) (Table 4-1).
32
This result was
in agreement with Chu's investigation.
33
In general, H. serrata is the most impor-
tant source of HA from the term of plant quantities, distribution, and HA content.
