Introduction: Garcinia cowa (Clusiaceae) is popular among integrative medicine in several communities. This study undertook to evaluate the anti-proliferative activity on cancer cells and its cytotoxic effect on normal cells. Here we are reporting for the first time the metabolomic profiling of G. cowa leaf. Methods: Anti-proliferative potential of ethyl acetate and methanol extract of Garcinia cowa leaf assessed by MTT assay. Metabolomic profiling obtained by GC/ MS analysis. Nuclear morphology visualized by DAPI staining. Caspase activation analysed through spectrophotometric assay. Results: The study reveals, that the methanolic extract is more potential in inducing anti-proliferative activity than ethyl acetate extract. Robust antiproliferative activity of the methanolic extract evidenced in lung cancer cell line, A549 followed by MCF{\textendash}7, HepG2, MOLT {\textendash} 4, MDA-MB-468 cells. The anti-proliferative effect was negligible in normal PBMC. Further, a dose-dependent increase of nuclear fragmentation visualized in A549 cells treated with the methanolic extract. Post methanolic extract treatment upregulation of caspase-3 and caspase-9 also evidenced in A549 cells. GC/MS analysis revealed the presence of phytoconstituents of different phytochemical groups comprising of 3.45\% diterpenoid, 5.45\% triterpenoid, 11.24\% steroid, 2.03\% phytosterol, etc. in methanol extract, as well as 4.53\% diterpenoid, 2.88\% triterpenoid, 1.09\% steroid, 2.11\% phytosterol, etc. in ethyl acetate extract with considerable biological importance. Conclusion: This is the maiden report of the metabolomic profiling of leaf extracts of Garcinia cowa which possess a good repository of potentially bioactive molecules that holds a great promise as a future therapeutic agent in combating lung cancer.

Objective: To find the anti inflammatory active compounds from methanol extract of Garcinia cowa. Methods: To evaluate the inhibitory activity of isolated compounds on nitric oxide (NO) production, culture media was assayed using Griess reaction. An equal volume of Griess reagent (1\% sulphanilamide and 0.1\% N-(L-naphthyl)-ethylene diamine dihydrochloride, dissolved in 2.5\% H3PO4) was mixed with culture supernatant and color development was measured at 550 nm using a micro plate reader. The amount of nitrite in the culture supernatant was calculated from a standard curve (0\–100 \μM) of sodium nitrite freshly prepared in deionized water. Percentage of the NO inhibition was calculated by using nitrate level of IFN-\γ/LPS-induced group as the control. Results: Isolated compounds, tetraprenyltoluquinone, rubraxanthone and \α-mangostin from stem bark of Garcinia cowa Roxb were evaluated for their anti-inflammatory activity. Only \α-mangostin exhibited strong anti-inflammatory activity with 83.42 \% inhibition of NO and without inducing severe cytotoxicity at 50M. Rubraxanthone showed weak inhibition of NO with 23.86 \% inhibition of NO while maintained 77.32 \% of cell viability. TPTQ also showed the strong inhibition of NO with 80.98 \% inhibition but unfortunately this compound also induced severe cytotoxicity with 39.62\% viability. Conclusion: \α-Mangostin exhibited strong anti-inflammatory activity without inducing severe cytotoxicity at 50 M. Rubraxanthone showed weak inhibition of NO while Tetraprenyltoluquinone also showed the strong inhibition of NO however this compound also induced severe cytotoxicity.
