- 摘要:
- 以红花龙胆为试材，采用徒手切片及石蜡组织切片法制作红花龙胆显微装片，采用氢化物原子荧光光谱法测定了其中的硒含量。结果表明：红花龙胆根皮层较宽，薄壁细胞内含贮藏物；茎皮层也较宽，管状中柱，髓部较大；叶上下表皮细胞椭圆形，栅栏组织细胞1～2列，维管束外韧型，叶表面观上表皮细胞不规则形，下表皮细胞多角枝状。该植物富含硒，叶中硒含量较高，平均为771. 246 μg/kg，其次是花与茎，根中硒含量较低，平均为195. 383 μg/kg，根达到粮食富硒食品标准，其余部位达粮食高硒食品标准。表明红花龙胆可作为富硒中草药使用。
- Abstract:
- Taking Gentiana rhodantha as material，the morphological characteristics and microstructure were described by using freehand section method and paraffin slice method；selenium content was determined by hydride generation atomic fluorescence spectrometry.The results showed that the root had a wider cortex，suborbicular xylem and unpith stele；the stem had a thicker cortex，siphonostele，continuous ring phloem and cambium，larger pith；the leaf epidermis cells were oval，palisade tissue cells were 1~2 lines，collateral bundle，upper epidermis cells of leaf were irregular and lower epidermis were angle branch.Meanwhile，the results also revealed that the average selenium content of leaf was 771. 246 μg/kg，and the flowers and stems took second place，and the average selenium content of root was 195. 383 μg/kg.Therefore，the selenium content of root reached selenium-enriched food standards，and the rest parts reached high selenium-enriched food standards.Gentiana rhodantha could be used as selenium-enriched in Chinese herbal medicine.
