Conditions
Polyalthia evecta exhibits potent anticancer activity against the malignant human hepatoma (HepG2) cell line. The 50% ethanolic extract of this plant demonstrated an $\text{IC}_{50}$ value of $70 \pm 3$ $\mu\text{g/ml}$ during cytotoxic activity screening. Furthermore, the species showed significant selectivity toward the HepG2 cells compared to the normal Vero cell line. This high selectivity index of greater than 14.3 highlights its ability to target cancer cells while sparing normal cells. Such findings suggest that Polyalthia evecta holds significant potential for future biopharmaceutical use in treating hepatoma.
Preparations
Polyalthia evecta is prepared as 50% ethanolic extracts to screen for cytotoxic activity against malignant human hepatoma cell lines. The plant is also prepared as general extracts to evaluate its potential for inhibiting intestinal disaccharidase activities. Furthermore, Polyalthia evecta is prepared as roots to facilitate the isolation of specific chemical compounds like 2-substituted furans. These various preparation methods allow researchers to investigate the plant's diverse anticancer, enzymatic, and antiviral properties. Through these different forms, the medicinal potential of the species is thoroughly explored.
Parts used
Polyalthia evecta contains specialized chemical constituents that can be found within its root system. Researchers have successfully isolated four new 2-substituted furans specifically from these roots. Through the use of various spectroscopic techniques, the unique structures of these compounds were clearly established. Scientific analysis revealed that certain isolated acids exhibit significant antiviral activity against Herpes simplex type 1. Furthermore, some of these root-derived compounds demonstrate promising antiplasmodial and cytotoxic properties.
