Sea buckthorn (Hippophaë rhamnoides ssp. rhamnoides) of varieties 'Terhi' and 'Tytti' and one of wild origin were cultivated in southern and northern Finland, harvested during 2007-2013. Proanthocyanidins (PAs) were analyzed with HILIC UPLC-ESI-MS. The southern and northern samples were separated in the partial least squares discriminant analysis model (four factors, R(2) 0.75, Q(2) 0.70). The total PAs were more abundant in berries from the north (610-970mg/100gDW) than in those from the south (340-450mg/100gDW) (p<0.05). In northern Finland, the length of the growth season as well as the temperature sum and radiation sum of the growth season until harvest were negatively correlated with the total PAs in all the samples but positively with PA oligomers in 'Tytti' and 'Terhi'. In southern Finland no respective correlations were seen. 'Terhi' and 'Tytti' had different trends in the content of total PA and oligomers in overripe stages.
对品种为“泰瑞”和“蒂蒂”以及一种野生沙棘（沙棘鼠李亚种）在芬兰南部和北部进行种植，并于2007 - 2013年期间收获。采用亲水相互作用超高效液相色谱 - 电喷雾电离质谱法（HILIC UPLC - ESI - MS）分析原花青素（PAs）。在偏最小二乘判别分析模型中（四个因子，R(2) 0.75，Q(2) 0.70），南部和北部的样本得以区分。北部浆果中的总原花青素含量（610 - 970mg/100g干重）高于南部（340 - 450mg/100g干重）（p<0.05）。在芬兰北部，生长季长度以及收获前生长季的积温和辐射量与所有样本中的总原花青素呈负相关，但与“蒂蒂”和“泰瑞”中的原花青素低聚物呈正相关。在芬兰南部未观察到相应的相关性。“泰瑞”和“蒂蒂”在过熟阶段总原花青素和低聚物含量呈现不同趋势。
