| Description | Dihydropinosylvinin is an phytoalexin, it shows antifungal activity against Cladosporium cladosporioides, Botryodiplodia theobromae, Aspergillus niger and Penicillium schlerotgenum, it also exhibits strong antibacterial activity against Bacillus cereus, Staphylococcus aureus, Pseudomonas aeruginosa and Escherichia coli.Dihydropinosylvin and batatasin IV can inhibit the germination of seeds of and root elongation in young seedlings of Sorghum bicolor. |
| In vitro | 被接种了Botryodiplodia theobromae或者处理过的水芋(Dioscorea alata)中发现了Dihydropinosylvin、batatasin IV、demethylbatatasin IV和batatasin III。这些化合物的诱导后，前三者显示出瞬时增加，这一增加先于苯丙氨酸解氨酶（phenylalanine ammonia lyase）活性的瞬时增加，但不包括酪氨酸解氨酶（tyrosine ammonia lyase）活性。 结论：在处理过的水芋块茎中，还观察到多酚氧化酶（polyphenol oxidase）的增加。具有诱导休眠作用的化合物Dihydropinosylvin和batatasin IV还发现能抑制高粱(Sorghum bicolor)种子的发芽和幼苗的根延长。相比之下，demethylbatatasin IV没有抑制作用。 |
