Coumarin itself was first isolated from the tonka bean Coumarouna odorata. Coumarin and its derivatives are alpha-benzopyrones. Coumarin is metabolized in humans to 7-hydroxycoumarin. Coumarin is a secondary phytochemical with hepatotoxic and carcinogenic properties. For the carcinogenic effect, a genotoxic mechanism was considered possible. Coumarins have a significant effect on physiological, bacteriostatic and anti-tumor activity. Coumarins have potent edema protective function and thus involved in the treatment of lymphedema, elephantiasis and other high protein edema conditions. Coumarin has appetite-suppressing properties.

Hesperidin is a flavanone glycoside found in citrus fruits. Its aglycone form is called hesperetin. Its name is derived from the word "hesperidium", for fruit produced by citrus trees. Hesperidin was first isolated in 1828 by French chemist Lebreton from the white inner layer of citrus peels (mesocarp, albedo). As a flavanone found in citrus fruits (such as oranges, lemons or pummelo fruits), hesperidin is under laboratory research for possible biological properties. One area of research is focused on the possible chemopreventive effects of hesperidin, but there is no current proof that hesperidin has this role in human cancer mechanisms. Hesperidin was effective in an animal model of Alzheimer's, alleviating pathological changes induced by aluminum. Early research suggests that taking one tablet of a specific product (Daflon 500, Les Laboratoires Servier) containing hesperidin and diosmin by mouth for 45 days decreases blood sugar levels and improves blood sugarcontrol in women with type 2 diabetes. For Rheumatoid arthritis (RA): early research suggests that drinking a beverage containing alpha-glucosyl hesperidin for 12 weeks improves symptoms of RA. Orally, hesperidin can cause gastrointestinal side effects, including abdominal pain, diarrhea, and gastritis. Headache can also occur in some patients. The possible anti-inflammatory action of hesperidin is probably due to the possible anti-inflammatory action of its aglycone hesperetin. Hesperetin appears to interfere with the metabolism of arachidonic acid as well as with histamine release. Hesperetin appears to inhibit phospholipase A2, lipoxygenase and cyclo-oxygenase. There is evidence that hesperetin inhibits histamine release from mast cells, which would account for the possible anti-allergic activity of hesperidin. The possible hypolipidemic effect of hesperidin is probably due to hesperetin's possible action in lipid lowering. Hesperetin may reduce plasma cholesterol levels by inhibition of 3-hydroxy-3-methylglutaryl coenzyme A (HMG CoA) reductase, as well as acyl coenzyme A: cholesterol acytransferase (ACAT). Inhibition of these enzymes by hesperetin has been demonstrated in rats fed a high cholesterol diet. The mechanism of hesperidin's possible vasoprotective action is unclear. Animal studies have shown that hesperidin decreases microvascular permeability. Hesperidin, itself or via hesperetin, may protect endothelial cells from hypoxia by stimulating certain mitochondrial enzymes, such as succinate dehydrogenase. The mechanism of hesperidin's possible anticarcinogenic action is also unclear. One explanation may be the inhibition of polyamine synthesis. Inhibition of lipoxygenase and cyclo-oxygenase is another possibility.

Cinchonine is cinchona bark alkaloid, which was used to treat malaria. Cinchonine is more efficient than quinine in increasing the intracellular accumulation and restoring the cytotoxicity of doxorubicin, mitoxantrone and vincristine on well-characterized multidrug resistance (MDR) cell lines. In the phase I of clinical trial was investigated the properties of cinchonine combined with the CHVP (cyclophosphamide, doxorubicin, vinblastine, methylprednisolone) regimen in relapsed and refractory lymphoproliferative syndromes.

Gentian violet ((GV) hexamethyl pararosaniline, also known as crystal violet, methyl violet) is a triphenylmethane dye with anti-bacterial, anti-fungal, anti-helminithic, anti-trypanosomal, anti-angiogenic and anti-tumor properties. GV has a lengthy history and has been used successfully as monotherapy and an adjunct to treatment in a variety of diseases. Gentian violet interacts with negatively charged components of bacterial cells including the lipopolysaccharide (on the cell wall), the peptidoglycan and DNA. A similar cell penetration and DNA binding process is thought to take place for fungal cells as well. Because Gentian violet is a mutagen and mitotic poison, cell growth is consequently inhibited. A photodynamic action of gentian violet, apparently mediated by a free-radical mechanism, has recently been described in bacteria and in the protozoan T. cruzi. Evidence also suggests that gentian violet dissipates the bacterial (and mitochondrial) membrane potential by inducing permeability. This is followed by respiratory inhibition. This anti-mitochondrial activity might explain gentian violet's efficacy towards both bacteria and yeast with relatively mild effects on mammalian cells.

Stearic Acid is a typical example of a fatty acid, which are essentially long hydrocarbon chains containing a carboxyl group at one end and a methyl group at the other. The chain lengths can vary from 3 (propionic acid) to 24 (lignoceric acid) but the majority of fatty acids found in hydrogenated vegetable or animal oils are around C16-C20 in length. Stearic acid is a saturated acid, since there are no double bonds between neighbouring carbon atoms. Stearic acid is found in various animal and plant fats, and is a major component of cocoa butter and shea butter. Stearic acid is a very common amino acid is used in the manufacturing of more than 3,200 skin and hair care products sold in the United States. On product labels, it is sometimes listed under other names, including Century 1240, cetylacetic acid, Emersol 120, Emersol 132, Emersol 150, Formula 300 and Glycon DP. Stearic Acid is mainly used in the production of detergents, soaps, and cosmetics such as shampoos and shaving cream products. Stearic acid is used along with castor oil for preparing softeners in textile sizing. Being inexpensively available and chemically benign, stearic acid finds many niche applications It is used in the manufacture of candles, and as a hardener in candies when mixed with simple sugar and corn syrup. It is also used to produce dietary supplements. In fireworks, stearic acid is often used to coat metal powders such as aluminum and iron. This prevents oxidation, allowing compositions to be stored for a longer period of time. Stearic acid is a common lubricant during injection molding and pressing of ceramic powders. It is also used as a mold release for foam latex that is baked in stone molds. Stearic acid is known antidiabetic and antioxidant agent.
Benzyl benzoate is an organic compound with the formula C6H5CH2O2CC6H5. It is the ester of benzyl alcohol and benzoic acid. It forms either a viscous liquid or solid flakes and has a weak, sweet-balsamic odor. It occurs in a number of blossoms (e. g. tuberose, hyacinth) and is a component of Balsam of Peru and Tolu balsam. It is on the World Health Organization's List of Essential Medicines, a list of the most important medication needed in a basic health system. Benzyl benzoate is one of the older preparations used to treat scabies. Scabies is a skin infection caused by the mite sarcoptes scabiei. It is characterised by severe itching (particularly at night), red spots, and may lead to a secondary infection. Benzyl benzoate is lethal to this mite and so is useful in the treatment of scabies. It is also used to treat lice infestation of the head and body. Benzyl benzoate is not the treatment of choice for scabies due to its irritant properties. Benzyl benzoate exerts toxic effects on the nervous system of the parasite, resulting in its death. It is also toxic to mite ova, though its exact mechanism of action is unknown. In vitro, benzyl benzoate has been found to kill the Sarcoptes mite within 5 minutes.
