摘要
选取东北大兴安岭地区的特色浆果花楸(Sorbus pohuashanensis H.)、蓝莓(Vaccinium uliginosum L.)、蓝靛果(Lonicera caerulea L.)、沙棘(Hippophae rhamnoides L.)、草莓(Fragariaorientalis Los.)的成熟果实,采用80%丙酮提取,分别测定多酚、黄酮、花色苷含量,并研究其抗氧化活性和抗细胞增殖活性。结果表明:花楸的多酚和黄酮含量最高;蓝靛果的花色苷含量最高,为(367.5±8.7)g/100g;5种浆果都具有较好的体外抗氧化活性,花楸显示了最高的抑制癌细胞增殖效应。
Some wild berries have been shown to have the functions of protecting against cardiovascular diseases,diabetes,and cancers due to the existence of phenolics.In the present study,the ripe fruits of five wild berries,Sorbus pohuashanensis H.（rowanberry）,Vaccinium uliginosum L.（blue honeysuckle）,Lonicera caerulea L.,Hippophae rhamnoides L.,and Fragaria orientalis Los.,selected from the Greater Higgnan Mountains area of Northeast China were extracted with 80% acetone and the extracts were measured for their contents of total phenolics,total flavonoids and anthocyanins,ABTS^＋·,DPPH and total oxyradical scavenging capacities and anti-proliferative activities against HepG2 and HT29 cell （MTS assay）.The results showed that rowanberry had the highest contents of total phenolics and total flavonoids among all the five berries,while blue honeysuckle had the highest anthocyanin content （367.5 ± 8.7） g/100 g.All the five berry extracts could exert antioxidant activities in vitro,of which rowanberry showed the highest inhibition effects on the proliferation of HepG2 and HT29 cells.As a conclusion,rowanberry has a huge potential for being developed as effective cancer drugs.
