(+)-Fenchone, a bicyclic monoterpene, is widely distributed in plants and found in essential oils from Foeniculum vulgare. This component has camphoraceous fragrance. (+)-Fenchone is used as a food flavour and in perfumes. Although, there are report that (+)-fenchone has toxic. P450 enzymes are shown to detoxify and/or toxify these compounds to metabolites more polar and sometimes more reactive metabolites. (+)-fenchone are oxidized to 6-endo-hydroxyfenchone, 6-exo-hydroxyfenchone and 10-hydroxyfenchone derivatives in human liver microsomes. CYP2A6 is suggested to be a principal enzyme in catalyzing (+)-fenchone 6-exo and 6-endo hydroxylation by human liver microsomes. 10-Hydroxylation of (+)-fenchone is also metabolized by CYP2B6.

Calcium lactobionate is calcium salt of a lactobionic acid. Lactobionic acid is a disaccharide formed from gluconic acid and galactose. Calcium lactobionate is a food additive used as a stabilizer due to high water binding capacity. It is also marketed worldwide as a supplement of calcium for the treatment of calcium deficiency, rickets, osteomalacia, heavy metal poisoning.

Calcium Fumarate is a calcium salt of fumaric acid, it can be used as a food supplement. Calcium Fumarate may be used to treat conditions caused by low Calcium levels such as bone loss (osteoporosis), weak bones (osteomalacia/rickets), decreased activity of the parathyroid gland (hypoparathyroidism), and a certain muscle disease (latent tetany). It may also be used in certain patients to make sure they are getting enough Calcium (e.g., women who are pregnant, nursing, or postmenopausal, people taking certain medications such as phenytoin, phenobarbital, or prednisone). Calcium Fumarate is classified by the FDA as a dietary and nutritional additive (21CFR§172.350) and has been used for many years.

Indoles and their derivatives are well-known as an important class of heterocyclic compounds, their core being a near-ubiquitous component of biologically active natural products, widespread in different species of plants, animals, and marine organisms. The indole is also well-known as one of the most important scaffolds for drug discovery, capable of serving as ligand for a diverse array of receptors. Indoles is used in textile dyes, perfumes, in agriculture and veterinary medicine. Relatively new areas are dietary supplements and nutraceuticals.
