[Pharmacognostic identification of Ferula syreitschikowii].

OBJECTIVE: To identify Ferula syreitschikowii by identification of pharmacognosy and provide the scientific evidence for its identification and application. METHODS: The crude drug identification, morphological, UV spectrum identifications, microscopic identification and thin layer chromatography (TLC) were adopted. RESULTS: There were specialization in morphology, microscopic characteristic, UV spectrum identifications and thin layer chromatography (TLC). CONCLUSION: These characteristics can be used for scientific basis for gruffs identification of crude drug and providing reference information for further development.

[Microscopic and TLC identification on the fruits of ten species plants for Umbelliferae].

The fruits of ten species plants of Umbelliferae, including the fruits of Peucedanum decursiyum, Saposhnikovia divaricata, Peucedanum terebinthaceun, Anethum graveolens, Cnidium monnieri, Angelica sinensis, Foeniculum vulgate, Angelica polymorpha, Ferula tunnshanica and Cicuta virosa were identified on histology and TLC.

The application of 3D chemical shift microscopy to noninvasive histochemistry.

Three-dimensional chemical shift imaging methods offer significant advantages over two-dimensional (chemical shift selective) techniques for the study of biological samples which exhibit complex spectra. We have applied 3D-CSI methods to the study of a plant system, (dried fennel mericarps) previously studied by 2D-CSI techniques, obtaining images with in-plane resolution down to 30 microns and special resolution of 0.4 ppm. A modification of the 3D-CSI technique which incorporates water suppression by a combination of pre-saturation and selective excitation is also described and its performance evaluated on both a phantom and a fresh fennel sample.
