Active Phytochemicals
1. Saponins (Triterpene glycosides)
They are usually bitter tasting toxic bioorganic compounds that have a foamy quality when agitated in water. They are used in medicine, soaps, also speciously used in dietary supplements for the synthesis of steroids and in carbonated beverages. Structurally they are glycosides, sugars attached to another organic molecule, usually a steroid or triterpene, a steroid building block.
Saponins are both fat and water soluble which gives them the soap properties. Saponins are used in ammonia emission in animal feeding. They have been reported in many edible legumes. They exhibit a biological role and medicinal properties such as haemolytic factor, cytotoxic ,anticancer, antimicrobial, insecticidal , anti-inflammatory and molluscicidal action.

2. Alkaloids
They are a class of naturally occurring basic organic compounds with at least one nitrogen atom. They uniformly evoke a bitter taste. They are uses in traditional and modern medicine and in starting of drug discovery. They are inducers of sexual behaviour in invertebrates and mammals.

3. Coumarins ( 2H-1-benzopyran-2-one)
It is a plant derived natural product known for its major pharmacological properties like antimicrobial, antioxidant, antihypertensive and neuroprotective properties. They consist of large class of phenolic substances found in plants and are made of fused benzene and alpha-pyrone rings.

4.Flavonoids
They area group of natural substances found with various phenolic substances found in fruits , vegetables, flowers, tea and wine. They are known for the beneficial effects on health and are considered as an indispensable component in variety of nutraceutical, medicinal, pharmaceutical and cosmetic applications. Three flavones were identified with chemical and spectroscopic techniques from Vernonia amygdalina. They were identified as luteolin, luteolin 7-O-beta-glucuronoside (most abundant), and luteolin 7-O-beta-glucoside.

5. Phenolic Acids
They are carboxylic acids derived from either benzoic or cinnamic acid skeletons. They have diverse utility including a role in nutrient uptake, structural components, enzyme activity, protein synthesis, photosynthesis, and allelopathy.

6. Lignin
7. Xanthones
8. Anthraquinone
9. Edotides
10. Sesquiterpenes (Vernolide and Vernodalol)
