Abstract

This study aims to analyze liquid smoke's chemical content and antioxidant activity from pyrolysis of nutmeg (Myristica fragrans) shell with rotary evaporator purification. A rotary evaporator purified liquid smoke from the pyrolysis of nutmeg shells. Identification of the chemical components of liquid smoke from the pyrolysis of nutmeg shells was carried out by Gas Chromatography-Mass Spectroscopy (GC-MS), and Antioxidants were measured using the DPPH (2,2-diphenyl-1-picrylhydrazyl) method with absorbance at a wavelength of λ 517 nm. The results of GC-MS analysis showed 14 peaks and 19 types of compounds detected with the 2-methylphenol compound component located at a retention time of 4.974 minutes, standing out with the largest contribution in terms of area, reaching 47.74%. The antioxidant test showed that the nutmeg shell has IC50 values before and after rotary evaporation of 0.40% and 0.07%, having strong antioxidant activity, and the results at a concentration of 3.2 mg/ml provided a level of free radical protection of more than 50%, namely 91.14%. The main compounds that play as antioxidants are phenol compounds and their derivatives, such as 2-methoxy-phenol and 2-methoxy-4-methyl-phenol.

Abstract

Background: Hypertension is a major challenge for Indonesia, as the disease is common in communities across the country. This is due to the many factors that cause hypertension including genetics, age, gender, ethnicity, stress, obesity, salt intake, high cholesterol intake, preserved foods, mutton, coffee and smoking. Objective: This study is to review one article with another article about the Relationship between Diet and Obesity with Hypertension. This type of research uses Literature Review research. Methods: articles were collected from search results on three databases such as Proquest, Pubmed and Google Scholar. With the criteria of articles published in 2015-2020, the author gets 20 articles and only 8 articles are used that match the research topic with a sample of 2176 respondents. Results: research from these eight articles showed an association between diet and obesity with the incidence of hypertension despite different research methods. Conclusion: based on the results of research and discussion, it can be concluded that an unhealthy diet and obesity can cause hypertension.
