GC-MS and ICP-OES Analysis of Secondary Metabolites From Traditional Rice Varieties of Andhra Pradesh, India

The popular varieties such as Navara, Parimala Sanna, Bahurupi, Sugandhi, and Indrani are commonly cultivated in Andhra Pradesh. Traditionally germinated red, black and brownrice has been used in Asian traditional medicine for centuries. Hence the present study is aimed to find out the metabolites from selected varieties by using standard methods. Qualitative analysis revealed the presence of a greater number of metabolites from aqueous extracts. The quantitative analysis highlighted the significant levels of flavonoids, proteins, carbohydrates, ascorbic acidand fatty acids from Parimala Sanna and Navara varieties. The GCMS analysis of Parimala Sanna aqueous extract revealed that the presence of 1,2,2-trichloroethane, 1,1-difluoro ethane, 1,2,5-oxadiazole, 4 methyl 4-pentane 2-one, formic acid, ethyl ester, 3-hydroxy-2 butanone with higher percentage. ICP OES analysis showed that the Sugandhi variety isricher in Iron, Sodium, Potassium, Sulphur and Copper than that of other varieties. This study will be helpful for isolation and identification of active principles from these rice varieties.
