Vibrational Spectroscopy-Based Chemometrics Analysis of Clinacanthus nutans Extracts after Postharvest Processing and Extract Effects on Cardiac C-Kit Cells

Figure 1

(a–d) Comparison of cell viability of CSCs after 96 hr treatment with C. nutans extracts against control (DMEM/F12) at different extraction parameters 1–4 (solvent polarity, solid-liquid ratio, extraction duration, and the cycle of extraction). Statistical analysis was conducted using Dunnett’s test. indicates that samples were significantly different from control (). Results were expressed in mean ± standard error of the mean (SEM), where n = 3.
