Anticancer Herbs and Phytoconstituents from Nature

Cancer represents one of the most significant global health challenges, characterized by uncontrolled cellular proliferation and high mortality rates. Conventional allopathic therapies, while effective to some degree, are often associated with severe side effects, high costs, and frequent recurrence. This has driven scientific interest toward natural alternatives—specifically herbs and phytoconstituents—that may offer preventive, prophylactic, and therapeutic benefits with better safety profiles and accessibility for broader populations.

Pharmaceutical Quality Control Hand Notes

Principle: HPLC is an analytical chemistry technique used to separate, identify, and quantify components in a mixture. It relies on pumps to pass a pressurized liquid solvent containing the sample mixture through a column filled with solid adsorbent material. Each component interacts differently with the adsorbent material, causing different flow rates and separation.
