|
Abstract:
在辽宁朝阳、甘肃庆阳，对6a沙棘人工林叶片在生长季逐月取样，分析与保健品开发有关的4个药食类主要营养指标，发现5月至7月采样分析的干叶总黄酮、总多酚、生物碱含量最高，此阶段可作为关键采叶时期，及时采叶后制作保健茶叶或生产其他保健用品。与引进沙棘和杂交沙棘相比，中国沙棘不管雌株还是雄株，其干叶所含主要保健营养成分的含量普遍最高，可用于生产沙棘叶保健品的主要材料来源。
Leaves of 6 year’s artificial seabuckthorn forests are picked up monthly in the growth period in Chaoyang, Liaojing, and Qingyang, Gansu, for analyzing 4 main ingredients contents related to medicine and food, and it indicates that the contents of total flavonoids, total polyphenol, and al-kaloid are higher in the period from May to July for leaves picking to other months, and this stage can be used as the key period of leaf picking to produce health tea or other health care products. Compared with that of introduced and hybrid ones, the functional ingredients contents of native seabuckthorn, including male and female, are the highest, thus the native seabuckthorn can be used for planting to pick leaves for industrial development, such as functional tea and other health products.
