Which of the phenolic classes are volatile?
Eugenol
What is a glycoside?
•Phenolic compound with a sugar group
What is a glycone?
The sugar moiety of a glycoside is known as the glycone
What is an aglycone?
•phenolic portion of a glycoside is the aglycone
How are Anthraquinones used medicinally?
•many are pigments, most well known class of plant-based laxatives and purgatives. Many occur as glycosides.
What is the difference among anthocyanins, anthocyanidins, and proanthocyanidins
All are pigments
anthocyanins are glycocides– anthocynadins with a sugar moiety
Anthocyanidins are structurally related to flavones, but carry a charge
Proanthocyanidins are related to flavonoid pigments, but have no sugar moiety. Oligomers and polymers of flavan-3-ol moieties
Which classes of phenolic compounds act as phytoestrogens?
Lignans
Explain why, from a chemical standpoint, phenolic compounds have antioxidant properties.
lots of double bonds allow them to have resonance stabilization
How many carbon are in a monoterpene?
•10-carbon molecules
How many carbons are in a sesquiterpene?
15 carbons
How many carbon are in a diterpene?
20
How many carbons in a triterpene?
30
Which classes of terpenes are volatile?
sesquiterpenes
What is a resin?
- A mixture of terpenoid molecules and other aromatic compounds that combine to form a solid or semi-solid substance that is excreted by plants for protection or in response to injury.
- The solid/semi-sold portion of resins are often di- and triterpenes, and the aromatic portion is commonly made up of mono- and sesquiterpenes.
- The aromatic components can be distilled from the heavier resinous components.
Define amphipathic
both hydrophilic and hydrophobic
What are saponins?
glycosides with a distinctive foaming characteristic
What are the basic properties of an alkaloid?
•Nitrogenous molecules – the nitrogen is often contained in a heterocyclic ring.
How are alkaloids classified?
by their amino acids
Define mucilage
•Form gels or slime with water.
What are the effects of bitters on the function of the GI tract?
production of saliva
vagal efferents
Bitter stimulates Ghrelin, which inc hunger and the cycle of satiety
inc CCK, which stimulates the secretion of bile and pancreatic juice
Stimulates motility
Anti-inflammatory to GI mucosa
Stimulates proliferation of mucosal cells
What type of compound are the bitter principles in Gentiana lutea?
Secoiridoid glycosides
What type of compound is, in large part, responsible for the antispasmodic action of carminative herbs
Volatile oils - monoterpenes
