REZUMAT
Ctina,Hippophae rhamnoides L.,este extrem de cunoscut datorit faptului c fructele
sale sunt foarte bogate n substane chimice: lipide, acizi grai nesaturai i saturai, vitamina C,vitamina E, steroli, flavonoide. Coninutul bogat n vitaminele D, E i n carotenoide confer
fructelor de ctin calitatea de surse de antioxidani. Fructele de ctin sunt utilizate n medicin
pentru tratamentul ulcerului gastic, pentru proprietile hepato-protectoare i antitumorale, pentru
stimularea imunitii; n industia farmaceutic pentru obinerea diferitelor preparate; n industria
alimentar ca pigmeni alimentari.Culoarea galben-portocalie a fructelor de ctin se datoreaz,
n principal, carotenoidelor existente n pulpa acestora. Coninutul de carotenoide n fructele de
ctin variaz de la 0,2-17 mg/100 g n funcie de varietatea studiat, de factorii climatici i de
condiiile de cultivare. Pentru a determina i doza compuii chimici se folosesc urmtoarele
metode: cromatografia de gaze (GC), cromatografia lichid de nalt performan (HPLC), GC -
spectometria de mas (GC-MS) i HPLC-spectometria de mas (HPLC-MS). Scopul lucrrii este
de a determina coninutul n vitamina C, vitamina E icarotenoide din diferite varieti de fructe
de ctin. Metoda folosit pentru dozarea vitaminei C este o metod volumetric, carotenoidele
i vitamina E se vor identifica folosind cromatografia lichid de nal performan.
CUVINTE CHEIE

ABSTRACT
Sea Buckthorn, H ippophae rhamnoidesL.,is well-known all over the world because its
fruits are rich in chemical substances: fats, unsaturated and saturated fatty acids, vitamin C,vitamin E, sterols, flavonoids. The rich content in vitamin D and E and in carotenoids gives to
the Sea Buckthorn fruits the quality of antioxidants sources. As a result of their chemical content,
Sea Buckthorn fruits are used in medicine for the treatment of gastric ulcer, for their hepato-
protective and antitumor properties, and as stimulators of the immune system; in pharmaceutical
industry for production of certain medicines; in food industry as food pigments. The yellow-
orange color of the fruits its due to the carotenoids pigments, which are contained by the pulp of
the fruit. The carotenoids content in seabuckthorn fruits are between 0,2 and 17mg/100g
depending on the variety studied, climatic factors and growing conditions. In order to determine
the chemical composition there were used the following methods: gas chromatography (GC),
high performance liquid chromatography (HPLC), gas chromatography-mass spectrometry (GC-
MS) and HPLC-MS. The aim of this paper is the determination of the amount of vitamin C,
vitamin E and carotenoids in several varieties of Sea Buckthorn fruits. The method used for
determination of vitamin C is a volumetric method, and the carotenoids and vitamin E will be
identified using HPLC technique.
KEY WORDS
Seabuckthorn berries, carotenoids, vitamin C and vitamin E
