化学的特性

Garlic oil is obtained by steam distillation of crushed bulbs of the common garlic, Allium sativum L.; it is produced mainly in China, Mexico, India, Egypt, and, on a smaller scale, also in Europe (France,Hungary) and is a clear, reddish-orange liquid, with a strong, pungent, characteristic garlic odor.

天然物の起源

Garlic is a perennial bulb found throughout the world

使用

garlic oil is considered a healing oil with bacteriostatic and bactericidal action. It is incorporated into skin care formulations for skin healing and to aid in clearing problems such as eczema and acne.

精油の成分

Although found in only small quantities, fresh garlic is a known source of several vitamins, minerals and trace elements Garlic is known to contain the highest sulfur content of any member of the allium genus The bulbs contain a colorless and odorless sulfur-containing amino acid called alliin (S-allyl-L-cysteine sulfoxide) Major chemical constituents of whole garlic include alliin (allylsulfnyl alanine), which is rapidly converted enzymatically when garlic is crushed to allicin (responsible for the characteristic odor of the essential oil and for the odor liberated from the crushed garlic clove), volatile and fatty acids, mucilage and albumin.

一般的な説明

Garlic (Allium sativum) is an herbal drug with references to medicinal properties that date back thousands of years. Of all the herbal remedies available to consumers, garlic is probably the most extensively researched.
Garlic contains a key component, alliin or S-methyl-lcysteine sulfoxide. Additionally, methiin (methylcysteine sulfoxide), cycloalliin, several γ-L-glutamyl-S-alkyl-Lcysteines, and alkyl alkanethiosulfinates are present. The tissues also contain enzymes (alliinase, peroxidase, myrosinase), as well as additional sulfur-containing compounds, ajoene, and other minor components.
Garlic itself has the highest sulfur content of all of the Allium species. When the garlic clove is crushed, the enzyme alliinase is released, and alliin is converted to allicin. Allicin gives garlic its characteristic odor and is believed to be the pharmacologically active ingredient from the herb. Alliinase will not survive the acidic environment of the stomach, so enteric-coated tablets are used. Garlic is most often studied for its lipid-lowering and antithrombotic effects. A cholesterol-lowering effect is well documented in both animals and humans. Garlic lowers serum cholesterol, triglycerides, and low-density lipoprotein (LDL) while increasing high-density lipoprotein (HDL).

抗がん研究

For many centuries, garlic has been used to treat a range of illnesses (Gupta et al.2004). Garlic oil contains a sulphur-holding substance known as ajoene oil or allicin.This oil has been found to control cancer cell production. The anticancer activityof garlic is thus due to its high levels of organic sulphides and polysulphides. Themechanism behind the antitumour activity triggered by stimulating the lymphocytesand macrophages is that they kill cancerous cells and interfere with tumour cells’metabolism. The administration method involves taking 5–6 cloves of crushed garlic,around 5 g/day (Kapoor 2000). The crushed cloves should sit for at least 15 minto release the allinase enzyme before consumption (Shareef et al. 2016).
