Comparative anatomy study on vegetative organs of Plantago major and P.depressa

大车前与平车前营养器官的比较解剖学研究

Little work has been reported on the tissue culture of Plantago major l.

大车前的组织培养工作，目前报道很少。

Plantago that produce dense spikes of small greenish flowers, especially either of two Eurasian weeds, P. major or P. lanceolata.

车前草一种车前草属植物，其淡绿色小花排成紧密的穗状花序，尤指两种欧亚大陆的野草大车前草或矛尖状车前草之一。

The result showed that the Ursolic acid Content in Prunella asiatica is 0.812%, which is the highest in three plants, and that in Plantago major is 0.516%, the lowest in three plants. The former is 1.57 tims as much as the latter.

测定结果表明：3种植物中，以夏枯草的熊果酸含量最高，达0812%，车前草的熊果酸含量最低，为0516%，前者是后者的157倍。
