2. Rosehip contains the highest amount of vitamin C among fruits and vegetables, and also contains vitamin A, B1, B2, B6, D, E, and K [9–12]. Besides ascorbic acid, citric acid, and malicacid are the characteristic organic acids of the fruit [13,14]. Rosehip is also rich in carotenoids; lycopene, ß-cryptoxanthin, ß-carotene, rubixanthin, gazaniaxanthin, and zeaxanthin are identified as its major components [5,10,15]. Active ingredients of rosehip are furthermore pectin and sugars, mainly glucose and fructose [5,11,14]. Rosehip’s essential oil contains alcohols, aldehydes, monoterpenes, sesquiterpenes, and esters. The most abundant components are vitispiran, α-E-acaridial, hexadecanoic acid, docosane (C22), ß-ionone, 6-methyl-5-hepten-2-one, 2-heptanone, heptanal, and myristic acid [14,16]. Rosehip seeds have a high content of polyunsaturated fatty acids, the dominant compounds are linoleic acid (45–55%), followed by α-linolenic acid (18–32%) and oleic acid (13–20%) [17–19]. Rosehip contains different mineral nutrients, mainly phosphorus, potassium, calcium, magnesium, manganese, and zinc. The mineral composition of rosehips is highly dependent on species and environmental conditions [12].
2.玫瑰果含有維生素C的水果和蔬菜中的最高量,並且還含有維生素A,B1,B2,B6,d,E,和K [9-12]。此外抗壞血酸,檸檬酸,和malicacid是水果[13,14]的特性有機酸。玫瑰果還含有豐富的類胡蘿蔔素; 番茄紅素,β-內隱黃質,β-胡蘿蔔素,rubixanthin,gazaniaxanthin,和玉米黃質被識別作為其主要組件[5,10,15]。玫瑰果的活性成分是果膠此外和糖,主要是葡萄糖和果糖[5,11,14]。玫瑰的精油含有醇類,醛類,單萜,倍半萜和酯。最豐富的組分是vitispiran,α-E-acaridial,十六烷酸,二十二烷(C22),SS-紫羅蘭酮,6-甲基-5-庚烯-2-酮,2-庚酮,庚醛,和肉荳蔻酸[14,16 ]。玫瑰果種子具有多不飽和脂肪酸含量高,佔主導地位的化合物是亞油酸(45-55%),其次是α亞麻酸(18-32%)和油酸(13-20%)[17-19] 。玫瑰果包含不同的礦質營養素,主要是磷,鉀,鈣,鎂,錳和鋅。玫瑰果的礦物組合物高度依賴於物種和環境條件[12]。
