ABSTRACT
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.

OBJECTIVE: To study the chemical constituents of Ligularia macrophylla. METHODS: Isolation and purification were carried out on repeated silica gel column chromatography. The structures of the compounds were identified by physico-chemical properties and spectral analyses. RESULTS: Eight compounds were isolated and identified as kaempferol (1), 2,4'-dihydroxy-5-methoxychalcone (2), 5-hydroxy-3,4', 7-trimethoxyflavone (3), isobutyl ester terephthalic acid (4), 4-hydroxybenzaldehyde (5), mono (2-ethylhexyl) terephthalate (6), lupeol (7), beta-sitosterol (8). CONCLUSION: Compounds 1 - 7 are isolated from this plant for the first time.

OBJECTIVE: To study the pharmacognosy of Nitraria tangutorum Bobr. systematically. METHODS: Macroscopic, microscopic identifications, physicochemical identification and UV spectrometry methods were carried out. RESULTS: The macroscopical, microscopical and physicochemical characteristics of Nitraria tangutorum Bobr. were decribed in details. CONCLUSION: The results can be taken as the reference for identifying the species, analyzing the quality and laying down quality standard of the crude drug.
