GC-MS profiling and in vitro antioxidant, cytotoxic and antimicrobial activities of Trianthema triquetra Rottl. ex Willed..
Pak J Pharm Sci Jan ;34(3):1127-34.

Trianthema triquetra Rottl. ex Willed is being used as a herbal remedy for various diseases in India and Pakistan. Still, no scientific data is available about therapeutic potential and phytochemistry of the plant. The aim of the current investigation is to perform GC-MS analysis, antioxidant (total phenolic and flavonoid content, DPPH assay), antimicrobial (disc diffusion assay) and cytotoxic (XTT and RBC's cellular membrane protection assay) studies. Methanolic extract and its fractions (n-hexane, ethyl-acetate, chloroform, n-butanol and water) were investigated for in vitro studies. Results showed that n-butanol fraction exhibited a significant (p<0.05) antioxidant potential (IC50=63.35±0.13 μg/mL) and also possess highest phenolic content (177±4.36 mg/g GAE). Whereas, n-hexane fraction showed highest flavonoid content (14.67±1.53 mg/g QE). 2, 4-Ditert-butyl-6-nitrophenol (26.79%) and Squalene (25.64%) were detected as major components through GC-MS analysis of chloroform fraction, eluted from column chromatography. Moreover, chloroform fraction also exhibited antimicrobial potential. Significant (p<0.05) dose dependent inhibition response on cell growth against CCRF-CEM cell lines was exhibited by methanolic extract. Furthermore, hemolytic potential of methanolic extract was found to be in safe range (2.23%-6.37%). So, it can be inferred that Trianthema triquetra can be exploited as an alternative remedy for cancer, oxidative stress related disorders and various skin diseases.
