Objective: To establish quality standard of Zhuang medicine Lonicera dasystyla, and provide scientific basis for the quality control of L. dasystyla.
Method: Characteristics of materia medica, microscopic features, TLC indentification, inspection, extractum and determination of chlorogenic acid, macranthoidin B, dipsacoside B were carried out through the experience, microscopic, physical and chemical methods, respectively.
Objective: To study the identification characters of Houttuynia cordata and its confused herb Gymnotheca chinensis and establish an identification method.
Methods: LMVP (leaf morphological-venation pattern for identification Chinese herbs), and QAERM (quantitatively analyze and evaluate reliability for the method of identification Chinese herbs) were applied for the study.
Results: Both venations were brochidodromous-acrodromous and arising from the mid-petiole or the upper section of petiole.
Objective: To study the identification characters of Abutilon indicum and its confused herb A. theophrasti and establish an identification method.
Method: LMVP (leaf morphological-venation pattern for identification Chinese herbs), and QAERM (quantitatively analyze and evaluate reliability for the method of identification Chinese herbs) were applied for the study.
Objective: To study the identification characters of Baphicacanthus cusia and its confused herb Clerodendrum cyrtophyllum and establish an identification method.
Methods: LMVP (leaf morphological-venation pattern for identification Chinese herbs) and QAERM (quantitatively analyze and evaluate reliability for the method of identification Chinese herbs) were applied for the study.
Results: The main differences of the leaf were as follows: Baphicacanthus cusia: leaf base attenuate, dry leaves deep dull blue green, spindle spots, no or small glandular scales somewhere, the limit between midrib and petiole was not clear, below undermost secondary vein some tertiary veins issue from midrib; Clerodendrum cyrtophyllum: leaf base not attenuate; dry leaves yellow green, green, green yellow, yellow brown, no spindle spots, densely covered by glandular scales,the limit between midrib and petiole was clear, below undermost secondary vein none tertiary veins issue from midrib.
Objective: To provide the scientific basis for the reasonable development and use of the leaves of Rhizoma Curcumae.
Methods: To extract the volatile oil from roots and leaves of three species Rhizoma Curcumae by steam distillation and isolate these products with the method of gas chromatography-mass spectrum. Taking Nist98 standard mass spectrometer database and contrast as control, the structure of the mass spectrogram was identified, and the relative contents of the components were determined with area normalization method.

Objective: To identify medical plant Murraya kwangsiensis by its tissue characters.
Method: Morphological characters and microstructure of this plant were described and illustrated.
Result: Oil cell, fiber cell and calcium oxalate prism were found in its tissue.
Objective: To study the characteristic features of Desmodium gyrans in order to provide a basis for rational exploitation and utilization of the herb.
Method: Samples of the title plant were collected, the microscopic features of cross sections and powders were studied. TLC profiles and UV absorption of the plant extract were examined.
Objective: To supply basis for the establishment of quality standard of Cryptolepis buchanaii.
Method: Characters of crude drugs, microscopic characteristic as well as UV spectrum of the herb were studied.
Result: Laticifers were found in the cortex and pith of the stem; much papillary non-glandular hair was found covering the stomata in the sub-cuticle of the leaf.
