Berries are known to have many kinds of biological activities. We focused on their antiviral effect, which has not yet been well evaluated.
We compared the anti-influenza viral effects of berries belonging to the genus Vaccinium - 35 species of blueberry (Vaccinium cyanococcus), the Natsuhaze (Vaccinium oldhamii), bilberry (Vaccinium myrtillus) and cranberry (Vaccinium oxycoccos)- with those belonging to the genus Ribes, i.e. blackcurrant (Ribes nigrum). Only Elliott and Legacy among Northern Highbush varieties but many Rabbiteye varieties such as Austin, Baldwin, Brightblue, Festival, T-100 and Tifblue showed anti-influenza viral activity. Natsuhaze, bilberry, cranberry and blackcurrant had high antiviral effects. A relationship was observed between the antiviral effect and total polyphenol content.
Antiviral effects were found to differ markedly between berry species. Rabbiteye varieties tended to have higher antiviral effects than Northern, Southern and Half Highbush blueberry varieties. We also found that Natsuhaze, which has recently been harvested in Japan as a potential functional food, had an antiviral effect comparable to that of bilberry, cranberry and blackcurrant. There was a positive relationship between antiviral activity and polyphenol content, indicating the possibility that polyphenol is one of the key factors in the antiviral effects of berries.
众所周知，浆果具有多种生物活性。我们专注于它们的抗病毒作用，而这尚未得到充分评估。
我们比较了属于 Vaccinium 属的浆果（35 种蓝莓[Vaccinium cyanococcus]、Natsuhaze [Vaccinium oldhamii]、越橘[Vaccinium myrtillus]和蔓越莓[Vaccinium oxycoccos]）与属于 Ribes 属的浆果（黑加仑[Ribes nigrum]）的抗流感病毒作用。只有 Northern Highbush 品种中的 Elliott 和 Legacy 以及许多 Rabbiteye 品种（如 Austin、Baldwin、Brightblue、Festival、T-100 和 Tifblue）表现出抗流感病毒活性。Natsuhaze、越橘、蔓越莓和黑加仑具有很高的抗病毒作用。抗病毒作用与总多酚含量之间存在相关性。
不同浆果品种的抗病毒作用存在明显差异。Rabbiteye 品种比 Northern、Southern 和 Half Highbush 蓝莓品种具有更高的抗病毒作用。我们还发现，Natsuhaze 作为一种有潜力的功能性食品，在日本最近已被收获，其抗病毒作用可与越橘、蔓越莓和黑加仑相媲美。抗病毒活性与多酚含量呈正相关，表明多酚可能是浆果抗病毒作用的关键因素之一。
