vitex rotundifolia L. is an important plant species used in traditional Chinese medicine. For its efficient use and conservation, genetic diversity and clonal variation of V. rotundifolia populations in China were investigated using inter-simple sequence repeat markers. Fourteen natural populations were included to estimate genetic diversity, and a large population with 135 individuals was used to analyze clonal variation and fine-scale spatial genetic structure. The overall genetic diversity （GD） of V. rotundifolia populations in China was moderate （GD=0.190）, with about 40% within-population variation. Across all populations surveyed, the average within-population diversity was moderate （P = 22.6%; GD = 0.086）. A relatively high genetic differentiation （Gst = 0.587） among populations was detected based on the analysis of molecular variance data. Such characteristics of V. rotundifofia are likely attributed to its sexual/asexual reproduction and limited gene flow. The genotypic diversity （D = 0.992） was greater than the average values of a clonal plant, indicating its significant reproduction through seedlings. Spatial autocorrelation analysis showed a clear within-population structure with gene clusters of approximately 20 m. Genetic diversity patterns of V. rotundifolia in China provide a useful guide for its efficient use and conservation by selecting particular populations displaying greater variation that may contain required medicinal compounds, and by sampling individuals in a population at 〉20 m spatial intervals to avoid collecting individuals with identical or similar genotypes.

Study on Extraction Technology of Total Flavonoids from vitex rotundifolia

引用

Agricultural Biotechnology 2015年第1期4卷 31-32,35页

作者： Xianping DAI School of Pharmacy Binzhou Medical University

[ Objective ] This study aimed to establish the optimal extraction technology of total flavonoids from vitex rotundifolia and provide a theoretical basis for the utilization and development of V. rotundifolia. [ Method ] With the extraction temperature, extraction time, solid-liquid ratio and ethanol concentration as various factors, the content of total flavonoids as an indicator, the extraction technology of total flavonoids from V. rotundifolia was optimized by orthogonal experiment. [ Result] The optimal combination of extraction conditions was extraction temperature 70℃, extraction time 1 h, solid-liquid ratio 1： 12, ethanol concentration 70%. [Condusion] The optimized extraction technology was simple and efficient for extracting total flavonoids from V. rotundifolia.
