| Abstract: | Twelve species ofArachniodes from Japan were examined for phloroglucinol derivatives and glandularity of rhizome and petiole bases. For comparison 3 species ofDryopteris, 1 species ofCtenitis, 4 species ofPolystichum, and 1 species ofAcystopteris were also investigated. Phloroglucinol derivatives were detected for the first time by sensitive TLC in the followingArachniodes, Dryopteris andPolystichum species:A. amabilis, A. dimorphophylla, A. exilis, A. hasseltii, A. maximowiczii, A. miqueliana, A. mutica, A. nipponica, A. okinawensis, A. simplicior incl. var.major, D. hayatae, D. sparsa, andP. tsus-simense. On the other hand,A. pseudo-aristata, A. standishii, P. polyblepharum, P. pseudomakinoi, P. retroso-paleaceum, Ctenitis maximowicziana, andAcystopteris japonica were totally lacking phloroglucinols. The phloroglucinol containing species ofArachniodes andPolystichum contained external glands, whereas those ofDryopteris contained internal and/or external glands. External glands are common inDryopteris sect. Nephrocystis. In taxa lacking phloroglucinols no glands were present. The homologous iso-aspidins BB and AB were detected in ferns for the first time. |
