Chinese fern, Pteris cretica, contains 2)8,15a-dihydroxy-(—)-kaur-16-ene (72) and 2)5,16a-dihydroxy-(—)-kaurane. The carbon skeleton of these diterpenoids was established by reduction to ( —)-kaurene and kauranol, whilst the oxygen functions were located by changes in the n.m.r. spectra on oxidation of the hydroxy-groups. The location of the hydroxy-function at C-2 was deduced from the multiplicity of the CH-OH resonance, which showed couplings to two axial and two equatorial protons.

From various plants belonging to the Polypodiaceae family, namely Inomotosou Pteris muhifide Poiret), Oobainomotosou (Pteris cretica L.) and Hitotsuba (Pyrrosia ingua Farw.) [3075]. 

In the metallomics and metalloproteomics studies, spatial analysis of absorbing atom of interest is also fascinating for elucidating the uptake and bio-transformation of different species of elements. An example studied the transformation of arsenic (Na2HAs04 or NaAs02) by the arsenic hyperaccumulator, Cretan brake Pteris cretica L. var nervosa Thunb). It was found that As tended to be reduced to As after it was taken up into the root, and arsenic was kept as As when it was transported to the above-ground tissues like petioles and pinnas. However, this example shows the spatial analysis at bulk scale therefore, this kind of XAS techniques can be called bulk-XAS. Using a microscopic mode of XAS, it is possible to obtain the information provided by bulk XAS at a spatial resolution of only a few micrometers or even... 

Using the modified Ames mutagenic test and two-dimensional thin-layer chromatography (317), Natori s group found that many of the pterosin- and pteroside-containing pteridaceous ferns contained ptaqui-loside-like compounds as well (282). Ptaquiloside (466) itself was found also in Pteris cretica L. (282) and the mutagenic hypolosides A (416), B (417), and C (418) were isolated from Hypolepis punctata. These compounds easily produce pterosin Z (419) when treated with alkali (258). 

One of the two groups consists of 2P-hydroxy- kauranes. In these compounds, the glycosidic linkages are formed only with the 2P hydroxyl group and the C- and D-rings are oxygenated exclusively on the a-side. They have been isolated from Pteris cretica 334 335, 336, 337), P. plumbea (342), P. multifida (191), P. dactylina (191) and P. ryukyuensis (91).
