Dried leaves of L. articulata were successfully extracted by using water extraction then separated with different solvent polarities; petroleum ether, ethyl acetate and butanol fractions before being analysed using GCTOF-MS, microplate reader and HPLC. The result from the GCTOF-MS analysis of fractional extracts showed that 48 compounds were found in petroleum ether, ethyl acetate and butanol extracts. From those extracts, only six phenolic compounds were identified in ethyl acetate and butanol extracts which were 2-Methoxy-4-vinylphenol, Phenol, 2,4- \u0000bis(1,1-dimethylethyl)-, 4-Hydroxybenzaldehyde, Catechol, Phenol, 2-methoxy- and Vanillin.

In this study, 12 seedlings of Ficus deltoidea Jack var. trengganuensis were sprayed with different concentrations of SA. Carotenoid content was determined using High-Performance Liquid Chromatography (HPLC) and chlorophyll content was determined using chlorophyll meter. Retinol activity equivalents were calculated using RAE formulation. From the results obtained, two types of carotenoids, lutein and β-carotene, were detected in HPLC. The highest lutein and β-carotene content present in Ficus deltoidea Jack var. trengganuensis leaves extract was found in 0.10 mM SA treatment (93.50 ± 0.71 μg/g DW) for lutein and (282.00 ± 46.67 μg/g DW) for βcarotene, while the lowest lutein compound was found in 1.00 mM SA treatment (30.25 ± 1.77 μg/g DW) while the least β-carotenoid content was found in (1.00 mM SA) treatment (63.00 ± 0.71 μg/g DW). The same goes for retinol activity equivalents, the highest retinol activity equivalents was recorded in 0.10 mM SA treatment while lowest in 1.00 mM SA treatment. For chlorophyll content, the highest reading was showed in 0.10 mM SA treatment (73.50 ± 0.71 μg/g DW) while the lowest reading was in 1.00mM SA treatment (42.10 ± 1.41 μg/g DW). From this study, it can be concluded that salicylic acid at a certain concentration could increase or improve the carotenoid or chlorophyll content.
