Phytosterols profile of tea seed oil

Abstract

This research work compares the phytosterol profiles of four bi-clonal tea seed stock oils i.e. TS 462, TS 464, TS 491, and TS 506. The phytosterols estimated by GC-FID exhibited that 24-methylene cycloartan-3-ol is the most abundant sterol in tea seed oil, accounting for 31% of the total phytosterols. The majority of the sterol differences were statistically significant (p< 0.05). TS 506 exhibited the highest amount of 24- methylene cycloartan-3-ol (476.03.7 mg kg-1) followed by TS 491 (475.97 mg kg-1). β-sitosterol, cycloartenol, canophyllol, lanosterol and campesterol were present with contents of 371.03 ± 0.26, 291.38 ± 0.12, 120.44 ± 0.13, 89.12 ± 0.19 and 69.05 ± 0.24 mg kg-1 respectively. Tea seed oils may also be effective n preventing cardiovascular diseases and delaying aging.
