In this Paper, the authors aim at understanding either the inmportance of the origin (the original features) of the brand logo or its audience's experience acts to be more effective. The purpose of the present study is the semiotic review of the 14 best-brand logos of automobile luxury goods through analysis of data and questionnaire which the authors can reach the rules governing on the brand logo with a focus on the two terms of the origin of the luxury brand's logo and its audience experience, and based on the indicators defined for each, within the framework of Barthes's visual semiotics and Van Leeuwen's social semiotics. The findings reveal that what is important to attract the attention of the customers of luxury automobiles in Iran is the audience's experience of the logo, which has tangibly got a head of the role of the origins and the identity of the goods. Accordingly, the difference in the perceived meanings of every brand logo by the audience indicates that the meanings received from every logo are not uniform and it is based on culture, so that individuals, based on their individual experience and their socio-cultural insights, understand the different implied meanings from a similar logo; it means the meanings received from every logo are not universal and regardless of audiences culture. This affects the success of the goods and maybe leads to different results in business.

Citrus Lemon is one of the medicinal herbs that is cultivated mainly because of its alkaloids, nutritional properties and antioxidants. Lemon peel extract is rich in tocopherol, phenol, flavonoids and vitamin C, and has an antioxidant activity. The purpose of current study was to investigate the effect of solvent, microwave and ultrasound extraction on the antioxidant properties of sour lemon extract. The effects of different methods extraction such as soaking, microwave and ultrasound carried out using water: ethanol solvent (30:70) on amount extraction of tocopherol and phenolic compounds and antioxidant activity, and the study of colorless process of β-carotene-linoleic and the amount of vitamin C in extract of lemon peel to obtain the best extraction efficiency for proper use of the extract. And the antioxidant activity and the inhibitory effect of the linoleic acid oxidation of the extract were compared with synthetic antioxidant BHT. The results showed that the phenolic compounds (480 mg gallic acid/gram), tocopherol (145 mg/ml) and ascorbic acid (85 mg/100 g) in the ultrasonic extraction method had the highest content. Also, the percentage of free radical scavenging DPPH (91%) and the colorless process of β-carotene-linoleic (58%) in the extract extracted by ultrasound showed the highest percentage of inhibition, however, they had a lower percentage of inhibition compared to BHT. According to the results of this study, using an ultrasound method, an extract can be obtained that does not significantly differ with the antioxidant BHT level in terms of antioxidant activity.
