[Study on correlation between the habits of growing development and the formation of morphology of Semiaquilegia adoxoides].

OBJECTIVES: To study the characteristics and regular patterns in growing development of Semiaquilegia adoxoides, and their correlation with the characters medicine materials. METHODS: Continuous observation and study was conducted during growth periods, and observation and measuring was adopted on commercially available Semiaquilegia adoxoides samples. RESULTS: Plants germinated from seeds and those in their first or second year since germinating from main roots had only basal leaves, there were no aboveground stems or process of flowering and fruiting. After that, plants would germinate from the top of main roots, flower and bear fruit, and the number of aboveground stem and flowers, the size of roots would increase gradually. The medicinal part of Semiaquilegia adoxoides should be fleshy tap root rather than root tuber. The aboveground plants of Semiaquilegia adoxoides experienced the growing process from autumn, through winter to the next spring. They flowered and bore fruit in spring and lived through summer with fleshy tap roots. There was relatively strong correlation between Semiaquilegia adoxoides's habits of growing development and temperature. The characters of Semiaquilegia adoxoides medicinal materials with various growth years were different, and the formation of Semiaquilegia adoxoides medicinal materials took more than 3 years under the wild state. CONCLUSION: The results provide a reference for cultivation and further utilization of Semiaquilegia adoxoides, and also serve as the basis for identification of Semiaquilegia adoxoides medicinal materials.

[Study on the histological anatomy on medicinal parts of Semiaquilegia adoxoides in different developmental stages].

OBJECTIVE: To study the structural characteristics of medicinal parts at different developmental stages of Semiaquilegia adoxoides. METHODS: Observed on sections of medicinal parts of Semiaquilegia adoxoides at various developmental stages during growth periods. RESULTS: There was a great difference between the upper and bottom of the medicinal parts of Semiaquilegia adoxoides: rhizome at the top of root had the structure of rhizome with pith; The upper one third of enlarged root was root-stem transition zone, also with pith; And the other two thirds of enlarged root had the structure of root without pith. The microscopic structures of the medicinal parts of Semiaquilegia adoxoides at various developmental stages presented great disparities, the structures regularly increased as the size of plant increased. It was the first time to find that there were structure of growth rings in xylem of the root and rhizome of Semiaquilegia adoxoides. CONCLUSION: The method of identification of characteristics and histology of medicinal parts of Semiaquilegia adoxoides at different developmental stages is established, and the results provide a basis for identification of Semiaquilegia adoxoides medicinal materials.

[Medicinal plant resources of Trib. Isopyreae and prospects of exploitation].

There are 17 species of medicinal plants from Trib. Isopyreae Schröd in China. This paper reports their resources, habitats and medicinal properties. On the basis of referring to the native and abroad medical studies on the plants from same Trilbe, their prospects of exploitation were advised.
