Neochlorogenic acid is a natural polyphenolic compound which can be found in a variety of plant sources and especially some types of dried fruit. It is an epimer of chlorogenic acid. Neochlorogenic has been investigated as a chemopreventative dietary compound for breast cancer and collorectal cancer. It has in-vitro anti-inflammatory properties, and may be responsible for the laxative effect fo prunes. Research surrounding neochlorgenic acid has often involved various plant extracts, rather than pure preparations of the compound.

Cryptochlorogenic acid is a structural isomer of chlorogenic acid; it is a cinnamate ester formed by the condensation of the carboxy group of trans-caffeic acid with the 4-hydroxy group of quinic acid. It can be isolated from several plant sources including apples, coffee, sunflowers, potatoes, and Hibiscus sabdariffa. Cryptochlorogenic acid mixed with related compounds has demonstrated potential anti-oxidant and anti-inflammatory properties and shown inhibitory activity against HBV DNA replication.
