The berries of sea buckthorn (Hippophaë rhamnoides ssp. rhamnoides) cultivars 'Terhi' and 'Tytti' were studied with respect to their growth location, 60° and 68°N latitude in Finland and 46°N in Canada, using H NMR metabolomics. The berries of 'Terhi' were characterised by stronger signals of quinic acid, while 'Tytti' had higher levels of O-ethyl β-d-glucopyranoside. The metabolic profile of the northernmost berries was distinctly different from those grown in southern Finland or Canada. Berries from northern Finland had relatively higher levels of quinic acid, glucose, l-quebrachitol and ascorbic acid. Ethyl glucoside was shown to accumulate by several fold at the late stage of maturation in the south as it correlated with degree days (r=0.63) and global radiation (r=0.59), but not in the north. The variance in the composition of the sea buckthorn berries demonstrates plasticity in the acclimatisation to growth environments.
利用核磁共振代谢组学方法，对沙棘（沙棘亚种鼠李沙棘）品种“泰瑞”和“蒂蒂”的浆果进行了研究，比较它们在芬兰北纬60°和68°以及加拿大北纬46°的生长环境下的差异。“泰瑞”浆果的奎尼酸信号更强，而“蒂蒂”的O - 乙基 - β - D - 吡喃葡萄糖苷含量更高。最北部浆果的代谢谱与芬兰南部或加拿大种植的浆果明显不同。芬兰北部的浆果中奎尼酸、葡萄糖、L - 异槲皮苷和抗坏血酸的含量相对较高。已证明，在南方，随着与度日数（r = 0.63）和全球辐射量（r = 0.59）相关，乙基葡萄糖苷在成熟后期会积累数倍，但在北方则不会。沙棘浆果成分的差异表明其在适应生长环境方面具有可塑性。
