[Correlation between chemical composition,ecological factors and soil factors of Chinese herbal medicine Daphnes Cortex].

In this paper, the correlation between the chemical constituents of Chinese herbal medicines Daphnes Cortex and the ecological factors and soil factors was studied, which provided a reference for the selection of suitable areas for artificial cultivation of Daphne giraldii and wild tending. The geographic information system(GIS) was applied to obtain the ecological factor information of 23 collection sites of Daphnes Cortex, and the soil factor information was determined by the standard procedure in the soil test standard manual. Combining the information of 93 chemical constituents of Daphnes Cortex in 23 collection sites the correlation between components and ecological factors and soil factors was analyzed by statistical methods.

[Investigation of ethnic medicinal plants Orobanche, Cistanche and Boschniakia].

In this paper the species of ethnic medicinal plants Orobanche, Cistanche and Boschniakia, and their ethnopharmaceutical uses were comprehensively summarized by field investigation, systematical data analysis and comparison of relevant specimen and references. The results showed that six plants belonging to Orobanche were used as seven kinds of ethnic medicinal plants, two plants attributing Boschniakia were used as ten kinds of ethnic medicinal plants, two plants of Cistanche were used as three ethnic medicinal plants. The same plant was often used as different ethnic medicine in varied ethnic minorities.

[Phenylethanoid glycosides distribution in medicinal plants of Gesneriaceae].

To investigate the role of distribution and phylogeny of phenylethanoid glycoside in medicinal plants of Gesneriaceae, five phenylpropanoid glycosides, acteoside, paraboside B, isonuomioside A, paraboside II, and paraboside III were quantitatively determined in 12 species of Gesneriaceae by HPLC. The existence and content of these compounds were analyzed. The results showed that phenylethanoid glycosides were found in the most of those plants, but the kind of phenylethanoid glycosides varied in different species.

[DNA identification of Zijingpi's adulterant species Schisandra sphenanthera based on NCBI nucleotide database analysis].

Objective: To provide basis for quality control of Zijingpi, DNA identification was used based on NCBI nucleotide database analysis.

Method: Firstly, total DNA of Zijingpi was extracted. Secondly, the ITS sequence was amplified by PCR with universal primer of ITS and PCR products was directly sequenced after purification.

[Investigation of Gesneriaceae ethnic medicinal plants in Guangxi Zhuang Autonomous Region].

Objective: To offer a scientific evidence for the study and exploration of Gesneriaceae ethnic medicinal plants in Guangxi Zhuang Autonomous Region by summinging up the species, distribution and traditional effect etc..

Methods: Made investigation in the local place and analyzed data, consulted relevant specimen and references.

Five new phenylpropanoid glycosides from Paraboea glutinosa (Gesneriaceae).

Five new phenylpropanoid glycosides, paraboside A, paraboside B, paraboside I, paraboside II and paraboside III along with the three known phenylethanoids, nuomioside A, caleolarioside B, isonuomioside A have been isolated from the whole plants of Paraboea glutinosa. The structures of the new compounds have been elucidated on the basis of spectroscopic data.

[Pharmacognostical and chemical studies of Lysinotus wilsonii].

Objective: To provide evidences for the pharmacognostical and chemical identification and the further development of Lysinotus wilsonii.

Method: The paraffin section method was used for the microscopic identifications of stems and leaves. The slide with chloral hydrate was applied for the microscopic identifications of the powder of stems and leaves.
