Abstract

Fruits of Actinidia arguta (Sieb. et Zucc.) Planch. ex Miq. are important source of bioactive substances including flavonoids. However, there were few reports on the phytochemical aspects of Actinidia arguta in different tissues. Here, we investigated the flavonoid content in different tissues of A. arguta by LC–MS/MS technology. In our study, ten flavonoids were detected, namely kaempferol-3-O-rutinoside (+), kaempferol-3-O-rutinoside (−), kaempferol-3-O-neohesperidoside (P), isorhamnetin-3-O-α-l-rhamnopyranosyl-(1→3)-α-l-rhamnopyranosyl-(1→ 6)-β-d-galactopyranoside, isorhamnetin-3-O-α-l-rhamnopyranosyl-(1→3)-α-l-rhamnopyranosyl-(1→6)-β-d-galactopyranoside, isorhamnetin-3-O-neohesperidoside (P)(+), isorhamnetin-3-O-neohesperidoside (P)(−), isorhamnetin-3-O-rutinoside, isorhamnetin-3-O-neohespeidoside, quercetin -3-O- rhamnoglycoside, which were belonged to kaempferol, isorhamnetin and quercetin, the major flavonoid compounds in Actinidia arguta, which decreased with the order of leaf > petiole > fruit. In young apical leaves, the total flavonoid content was 6.3-fold higher than that in fruit. And there was a continuous decrease as leaf development in total flavonoids content. In addition, except AaCHS-2 and AaDFR, the expression levels of nine genes-related flavonoid biosynthesis were similar to the change of total flavonoids content in different tissues. It indicated that the eleven genes played main regulation in flavonoid biosynthesis. Thus, our results revealed the regulatory information of flavonoid biosynthesis in Actinidia arguta leaves and provide technical support for the full utilization of leaves.
