In order to systematically learn the VC content of the introduced macro-fruit Hippophae rhamnoides and the newly selected Mongolian-Chinese-Hybrid H. rhamnoides clones, the two kinds of H. rhamnoides fruits in Suiling County of Heilongjiang Province were sampled in 2018,packed in liquid nitrogen tanks and quickly transported to Dalian, Liaoning, and the VC content was then analyzed by liquid chromatography. The average VC content of dried whole fruit for 18 introduced H. rhamnoides is 671.58 mg·(100 g)~(-1). In the 18 introduced H. rhamnoides clones, there are four clones with a content of more than 1 000 mg·(100 g)~(-1) H. rhamnoides ‘201319',H. rhamnoides‘201303',H. rhamnoides‘201316'& H. rhamnoides‘201313',while the content of H. rhamnoides ‘201315' with the lowest content was only 124.40 mg·(100 g)~(-1),which is only equivalent to 7.31% of H. rhamnoides ‘201319' with the highest content. The average content of the dried whole fruit of hybrid H. rhamnoides is 1 338.45 mg·(100 g)~(-1),and H. rhamnoides ‘Zaciyou 54' is the largest, up to 209 2.88 mg·(100 g)~(-1),which is 2.05 times that of H. rhamnoides ‘Zaciyou 12' with the lowest content of 654.28 m·(100 g)~(-1). Compared with the introduced H. rhamnoides,the content of VC in the dried whole fruit of hybrid H. rhamnoides is equivalent to a doubling of the constant. The difference between the two categories is very obvious.
