Leaves basal, distichous; petiole well developed, base sheathing; leaf blade lanceolate or oblong, with several pairs of longitudinal veins parallel to a distinct midvein.

茎非常短。叶基生，二列；叶柄明显，基部具鞘；叶片披针形或者长圆形，有几对平行的纵裂或一个显著的中脉。

Leaves basal, tufted, usually slightly distichous equitant, sessile, base dilated.

The antifungal activities of these materials were investigated and build foundation to develop low poison plant antifungal products. In experiment, polyphenols were extracted by reflux ectraction method which applyed petroleum ether to degrease and methyl alcohol solvent. Phenolic hydroxyl were examined and inspected by colour-developing reaction and the content of total polyphenols was determined by UV-spectrophotometry. Screening test were performed to the antifungal activities of polyphenol extraction by the tube dilution method to the selected ten pathogenic fungus such as Dothiorella gregaria, Rhizoctonia solani, Phyllosticta pirina, and the minimal inhibitory concentration were measured. The column chromatography and thin layer chromatography were applyed to separate and analyse cortex extracts of Dracaena cochinchinensi Lour.

实验部分采用以石油醚脱脂，甲醇为溶剂的回流提取法来提取植物多酚，用显色反应检识酚羟基；采用紫外分光光度法对多酚粗体物进行总多酚含量的测定；选取了聚生小穴壳菌、立枯丝核菌、梨叶点霉等10株常见农林业致病真菌，采用试管液基稀释法对多酚粗提取物进行了抗真菌活性筛选试验，并测定其最低抑菌浓度；采用柱层析法和薄层层析法对其中抑菌效果较好的龙血竭进行分离分析，根据其中3种化合物的光谱数据UV、IR、~(13C-NMR、1H-NMR和MS鉴定其结构。
