摘　　要：目的分析种植于潮汕沿海海蓬子的营养成分,并对其安全性进行初步评价。方法采用常规生化分析方法。结果海蓬子嫩茎的含水量较低(90.99%),灰分(3.42%)、维生素C(40.66mg/100g)和β-胡萝卜素(1.74mg/100g)含量高,含有八种必需氨基酸,谷氨酸、精氨酸含量丰富、但缺乏含硫氨基酸,其他营养成分多数高于茎菜类蔬菜。种籽中蛋白质(34.01%)、油脂(23.79%)和维生素E(23.6mg/100g)含量都很高,其蛋白质质量较好。种油主要由亚油酸(70.62%),油酸(12.19%),棕榈酸(10.37%),亚麻酸(2.93%)等组成,有较高的营养和保健价值。小鼠急性毒性试验LD50>464g/kg。结论海蓬子营养丰富,食用安全,有很好的开发利用前景。Objective To analyze the nutritional components of Salicornia bigelovii Torr.of Chaoshan coasta and briefly evaluate its safety.Method The nutritional components were analyzed with GB （national standards methods） and other related methods,and determination of median lethal dose was used by Horn methods.Results In Salicornia bigelovii Torr.tender stem,the content of water was low （90.99%）,mineral （3.42%）,vitamin C（40.66 mg/100g）and β-carotene（1.74 mg/100g）were high.Eight essential amino acids were contained,and glutamic acid and arginine were rich but sulfur amino acids were deficient.And most of other nutrients which contained were higher than other stem vegetables.In Salicornia bigelovii Torr.＇s seed,the content of protein （34.01%）,oil （23.79%）and vitamins E （23.6 mg/100g） were high,and the quality of protein was better.The oil was mainly composed of linoleic acid （70.62%）,oleic acid （12.19%）,palmitic acid （10.37%）,linolenic acid （2.93%） and so on,showing great nutritional value,and acute toxicity LD50464 g/kg.Conclusion The nutrients of Salicornia bigelovii Torr.are rich,safe to eat,and worth to develop and utilize.
