Abstract
We investigated the physicochemical properties chemical composition stability and antioxidant activity from seed oil of Salicornia herbaciea grown in Korea The density refractive index acid value peroxide value iodine value saponification value and unsaponifiable matter of oil were 091mg/mL 148 at 20 °C 189mg KOH/g oil 1020 mEq/kg oil 108 g I/g oil 21621 mg KOH/g oil and 260 respectively The major fatty acids were linoleic acid 4373 oleic acid 1981 arachidic acid 1352 and palmitic acid 1184 respectively The oil contained high levels of αtocopherol 2492 mg/kg oil followed by δtocopherol 893 mg/kg and γtocopherol 756 mg/kg oil The oil was found to have high levels of βsitosterol 945mg/kg oil and stigmasterol 657mg/kg oil respectively The total phenol chlorophyll and βcarotene content of oil was 152 945 and 82 mg/kg oil respectively The oil had good oxidative stability during 60 days of storage in a dark area at 50 °C The maximum degradation rates of the oil were observed at 2423 °C 95/min 3826 °C 52/min and 4407 °C 13/min respectively where the rate of the weight decrease increased to a maximum up to this point The ABTS radical scavenging activity of the oil was increased from 502 to 718 when the oil concentration extracted by methanol was increased from 100 to 300 μg/mL This study suggests that S herbaciea seed oil has potential use in functional foods cosmetics or pharmaceuticals
