对来自拉浩地区 (半干旱地区 )与斯皮特 (干旱地区 )的 8年生沙棘种子与果肉粗提物中脂肪酸组成进行了研究。所选的中亚沙棘产自拉浩与斯皮特 ,同时研究的还有来自拉浩地区的柳叶沙棘与HI 1型沙棘 (外来品种 ) ,该外来品种种植在喜马偕尔邦农业大学高山农业研究与推广中心。该研究中心位于拉浩 斯皮特地区的拉浩谷地的库坎姆西瑞 (海拔 2 730m) ,处于印度温和干燥的喜马拉雅山地区。在所有种类的果肉油脂中 ,不饱和脂肪酸含量的比例 (5 2 8%～ 6 0 7% )高于饱和脂肪酸 (10 6 %～ 2 9 9% )。同样 ,除了柳叶沙棘以外 ,种子油脂中不饱和脂肪酸含量 (5 1 7%～ 86 5 % )要高于饱和脂肪酸含量(12 5 %～ 2 7 2 % )。在果肉油脂中 ,主要的饱和脂肪酸是棕榈油酸 (37 1%～ 4 6 4 % )、亚油酸 (6 4 %～15 0 % )、油酸 (4 0 %～ 6 9% )和软脂酸 (9 1%～ 2 8 1% )。柳叶沙棘果肉油脂中含有丰富的亚油酸(15 0 % )和α 亚麻酸 (1 3% )。棕榈油酸是最主要的不饱和脂肪酸 (37 1%～ 4 6 4 % ) ,在拉浩种群中含量最高 (4 6 4 % )。软脂酸是主要的饱和脂肪酸 ,除了斯皮特种群 (9 1% ) ,其他类型中的含量基本相同(2 6 4 %～ 2 8 1% )。在种子油脂中 ,斯皮特种群中含量最丰富的是亚油酸 (39 8% )和α 亚麻酸(2
The fatty acid composition of 8-year-old Seabuckthorn seeds and pulp crude extracts from Lahoo (semi-arid area) and Spit (arid area) was studied. The selected Central Asia seabuckthorn was produced by Lahoe and Spitt and also studied willow seabuckthorn and HI type Hippophae rhamnoides (exotic species) from Lahoo, which were planted in alpine mountains of Himachal Pradesh Agricultural University Agricultural Research and Extension Center. The research center is located in Kukumsirui (2 730m above sea level) in the Laho Valley of La Hautespeed in the mild and dry Himalayas of India. Among all kinds of flesh fats, the proportion of unsaturated fatty acids (528% ~ 607%) was higher than saturated fatty acids (106% ~ 299%). Similarly, the content of unsaturated fatty acids (51.7% -86.5%) in seed oils was higher than that of saturated fatty acids (12.5% -272%), except for seabuckthorn. Among the fats, the main saturated fatty acids are palmitoleic acid (371% -446%), linoleic acid (64% ~ 150%), oleic acid (40% ~ 69%) and soft Fatty acid (9 1% ~ 2 8 1%). Willow leaf seabuckthorn fruit flesh oil is rich in linoleic acid (150%) and α-linolenic acid (13%). Palmitoleic acid is the most important unsaturated fatty acid (371% ~ 464%), the highest content of Lahao population (464%). Palmitate is the major saturated fatty acid, with the exception of the Spit population (9 1%), which is essentially the same in other types (26.4% -281%). Among the seed oils, the most abundant species in the Spit population is linoleic acid (39.8%) and alpha linolenic acid (2
