Espada plant, local name for the snake plant (Dracaena trifasciata) in the Philippines, is characterized by its upright sword-like leaves with vibrant yellow edges under the variety of Laurentii in the Asparagaceae family. This plant has been identified as a viable candidate for cancer research.

To investigate the antiproliferative and cytotoxic capabilities of a semi-purified methanolic extract of D. trifasciata extracted as a basis for cancer research.

The plant extracts were subjected to (1) qualitative phytochemical analysis, (2) instrumentation analysis which includes Fourier Transform Infrared Spectroscopy (FTIR-ATR) and Total Flavonoid Content (TFC), to quantify bioactive ingredients, analyze structures, and evaluate biological chemicals, respectively, and tested to (3) biological assay on the HCT 116 human colorectal cancer cell line using the MTT Cytotoxic Assay.

D. trifasciata extracts revealed the presence of flavonoids, saponins, sterols, triterpenes, alkaloids, and glycosides, all of which contain an OH group and have a high solubility in polar solvents. It correlates to the results of TFC, found to be within 266.8333 mg – 622.6801 mg presented as ?g Quercetin per mL with a linear line of y=0.0005x + 0.023 with a coefficient R2 value of 0.9933. This finding corresponds to FTIR-ATR data, which shows a prominent broad appearance of -OH (primary and secondary alcohol) at peak 3327.21. In MTT Cytotoxic Assay, it has a minimal IC50 than Doxorubicin, as seen in Trial 2 with IC50 = 0.8012 ?g/mL, while antiproliferative activity revealed that D. trifasciata has minimal inhibitory activity in Trials 1 and 3 at the same concentration of 3.125 ?g/ mL as compared to the high antiproliferative property of positive control, as seen in Trial 2. Data showed that the D. trifasciata extract has minimal effectiveness even at 1.56 ?g/mL concentration, implying that other extraction techniques such as fractionation and purification may be used to satisfy its antiproliferative property.

The D. trifasciata extract contains polyalcohol, phenol, polyphenol, and polyhydroxylated metabolites, which are structures that correspond to the major groups of flavonoids (structures that have antioxidant properties), contributing to the high TFC values.
