Abstract:
Tea is the most widely consumed beverage in the world. It has potential in
pharmaceutical industry applications because it contains many nutrients and phytochemical
beneficial for human health. Thus, this research was aimed to investigate the chemical
constituents by GC-MS and HPLC and evaluate antioxidant activity of Camellia sinensis var.
assamica. The main chemical constituents identified by HPLC demonstrated the presence of
caffeine, gallocatechin (GC), catechin (C), epicatechin (EC), epigallocatechin gallate (EGCG),
gallocatechingallate (GCG), epigallocatechin (EGC), epicatechingallate (ECG) and gallic acid
(GA). GC-MS analysis showed the presence of phytol, phenylethyl alcohol and linalool in the
volatile oil. Furthermore, total phenolic content was measured by Folin-Ciocalteu method while
antioxidant activity was evaluated by using DPPH radical scavenging assay and FRAP assay.
It was found that tea leaves extracted with 80% acetone showed the antioxidant activities with
IC50 value of 24.22 μg/mL and 211.12 mg GAE/g of FRAP assay and also contained the total
phenolic content of 231.64 mg GAE/g.
