[Pharmacognostical and chemical studies of Lysinotus wilsonii].
OBJECTIVE
To provide evidences for the pharmacognostical and chemical identification and the further development of Lysinotus wilsonii.


METHODS
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. The HPLC was used for the identification of the phenylpropanoids.


RESULTS
An obvious periderm consisted of a line of inseparable cells, lots of stone cells existed in the periderm and cortex, narrow ring of xylem and broad pith could be easily observed in the stem transaction of L. wilsonii. Epidermis was composed of one lines of parenchyma, three lines of epithelial cells in the side of above epidermis, palisade tissue was composed of 2-3 lines of square and thin cells and amphicribral vascular bundle in transaction of midrib also could be observed in the leaf transaction of L. wilsonii. Long xylem fibers, lots of pitted vessels, stone cells and anomocytic type stomas existed in the powder of L. wilsonii. Acteosidel and caleolarioside B were detected in L wilsonii.


CONCLUSIONS
The pharmacognostic and chemical characteristics of L. wilsonii can be used for authentication of the plant.
