凤仙花不同提取物中山奈酚的测定

为寻求有效的山奈酚分离、纯化条件,并从凤仙花中提取山奈酚;分别采用不同溶剂和不同方法对凤仙花红色花瓣进行了提取,并利用高效液相色谱法对其主成分进行了测定;实验结果表明: 9种提取物中均含有山奈酚,乙酸乙酯提取物中山奈酚的含量最高: 1 g凤仙花红色花瓣的乙酸乙酯提取液中含有8.1 mg的山奈酚.     

邻二氮菲苯妥英合锰(Ⅱ)三元配合物的合成、结构与抗微生物活性研究

The title complex [Mn(pht)₂(phen)] (Hpht=5，5-diphenylimidazoline-2，4-dione， phen=1，10-phenanthroline) was synthesized and characterized by elemental analysis， IR and X-ray diffraction single-crystal structure analysis. The compound crystallizes in the monoclinic system， space group C2/c with a=2.631 5(16) nm， b=0.924 5(6) nm， c=1.550 8(10) nm， β=116.231(7)°; V=3.384(4) nm³，M_r=737.66， Z=4， F(000)=1 524， D_c=1.448 g·cm^-3， μ=0.446 mm^-1， the final R=0.069 9 and wR=0.195 3. The complex was valued for its antimicrobial activity against some bacteria in vitro. It was found to be active against the four test bacterial organisms. CCDC: 616309.
