Rubralactone (1), rubralides A, B and C (2-4), rubramin (5), and 2-formyl-3,5-dihydroxy-4-methylbenzoic acid (6), were isolated from Penicillium rubrum, and their structures established by spectroscopic methods including 2D NMR. The effects on plant growth of 1-6 were examined using the lettuce seedling bioassay. Compound 1 promoted root growth. Compounds 2, 3 and 5 inhibited the growth of lettuce seedlings, but 4 and 6 did not have any inhibitory effect on their growth.
从红青霉中分离得到了红曲内酯(1)、红曲内酯A、B和C(2 - 4)、红曲胺(5)以及2 - 甲酰基 - 3,5 - 二羟基 - 4 - 甲基苯甲酸(6),并通过包括二维核磁共振在内的光谱方法确定了它们的结构。使用生菜幼苗生物测定法研究了1 - 6对植物生长的影响。化合物1促进根系生长。化合物2、3和5抑制生菜幼苗的生长,但4和6对其生长没有任何抑制作用。
