It is well known that neonatal animal may die early or grow slowly if they don t suck colostrums enough, so it proves colostrums have enormous effect on growth and development of neonatal animal.
初乳因理化因素不同于常乳,而刚出生的动物没有吮吸到充足的初乳则成活率较低,并且影响到后期的生长发育,这些都说明初乳对新生动物的生长发育具有较大的作用,但其机理除报道的含有较多的促生长活性物质和免疫作用外,还有一个不容忽视的营养作用,只有了解了这方面的作用,才能对初乳的应用及进一步开发起到推动作用。
A new derivative of 1 named 7-hydroxy-9-methoxy-1-methyl-6-oxo-6H-benzo[c] chromen-3-yl acetate(4) was prepared through esterification.
从南海红树林麒麟菜内生真菌E33中分离到6个化合物,其中alternariol monomethyl ether(1),alterna-riol(2),dehydroaltenusin(3)为首次从海洋红树林真菌里得到,通过酯化反应制备了化合物1的新衍生物7-hy-droxy-9-methoxy-1-methyl-6-oxo-6H-benzo[c]chromen-3-ylacetate(4),这4个化合物对hepG2细胞显示了微弱的细胞毒活性。
