RESUMEN
OBJECTIVE: To provide reference for identification and development of Basella rubra. METHODS: Microscopic identification and UV spectrometry methods were used. RESULTS: Obvious characteristics were found in the tissue structures of the roots, stems and leaves . And Basella rubra showed some UV spectrometry characteristics. CONCLUSION: The results can be used as the reference for analyzing the quality of the crude drug.

OBJECTIVE: To study the microscopic and UV-Vis spectrum characteristic of Sapium sebiferum. METHODS: The microscopic identification and UV-Vis spectrum identification were adopted. RESULTS: There were cluster crystals in cortical cells of roots and stems and parenchyma cells of the leaves. A few stone cells were found in cortex of the stem. The vascular bundles arranged in the form of a circle in the main vein of the leaves. It could be observed that many crystals and crystal fibers in the powder. Six kinds of solvent of crude drug had absorption peaks between 200 - 800 nm. CONCLUSION: These results can provide the scientific evidence for the establishment of standard for quality control and further study.

OBJECTIVE: To Analyze the chemical composition and their relative contents of essential oil from the leaves and fruits of Eucalyptus tereticornis in Guangxi province. METHODS: The column temperature was controlled by a program with a capillary column HP-5 MS, and the MS analysis was performed with EI and quadrupole mass analyzer. The chemical compositions were identified by NIST98 searching and mass spectra comparing, and their relative contents were determined by using normalization method of chromatographic peak areas. RESULTS: 39 compounds constituting 96.69% of the oil of leaves were identified. The major components were eucalyptol (27.93%), 1R-alpha-pinene (22.60%), isopinocarveol (8.71%); 36 compounds constituting 93.50% of the oil of fruits were identified. The major components are 1R-alpha-pinene (32.88%), eucalyptol (13.64%), D-limonene (8.31%). CONCLUSION: The GC-MS is a simple, rapid and sensitive method.
