Identification of Daemonorops draco Bl. by near-infrared diffuse reflectance spectrometry combined with visualization of convolution transform 近红外漫反射光谱的可视化褶合变换技术用于血竭的鉴别
Daemonorops draco was studied by alcohol extraction, dissolution with acid water, alkalization and separation procedure with using chloroform ∶ methanol ( 19 ∶ 1) as developing solvent. 采用醇提、酸溶、碱化、萃取等步骤提取血竭中的血竭素,以氯仿甲醇(19∶1)为展开剂。
