  1. Notes: Human breast cancer cells MCF-7 (ATCC-HTB-22), colorectal cancer cells HT-29 (ATCC HTB-38), cervical cancer cells HeLa (ATCC CCL2) and liver cancer cells Hep-G2 (ATCC HB-8065) are anchorage-dependent cells while leukemia cells HL60 (ATCC CCL-240) and K562 (ATCC CCL-243) are suspension cells. The highest concentration of PM being tested on all cells was 30% (v/v). The IC50 values were detected after 72 h of incubation. The values reported are the means of nine replicates. N.D., no IC50 values were detected up to the concentration of 30% (v/v)
