A method for simultaneous separation and determination of two coumarins,dicumarol and cyclocoumarol,in cosmetics by HPLC-diode-array detector(DAD) was developed.
The primary synthetic methods of 4-hydroxycoumarin was reviewed starting from phenol, 2-acetylsalicylic acid, methyl salicylate, and o-hydroxyacetophenone respectively.
A proof that most of the steps for the reaction of Dihydrocoumarin are consecutive has been given from kinetic experiments and analytical results of the products.
(Sweet legumin of 2) heparin and benzyl acetone: Can improve Gao Ning position of blood, and prevent kidney spherule sclerosis and new moon bodily form to become.
In the group of dicoumarol plus doxorubicin, serum ALT, LDH, CK activities were significantly increased as compared with that of doxorubicin group alone, and liver MDA content was also increased.
This bad skin reaction is caused by certain furanocoumarins, a group of compounds that some plants use to defend themselves and deter hungry herbivores.
Not to mention that cinnamon contains a chemical compound called Coumarin, and when ingested in large quantities, can actually cause liver damage in susceptible individuals.
There are also acquired forms of protein C or S deficiency, like impaired production as seen in patients with liver disease or in patients taking warfarin, also called coumadin.
As humans, our opposable thumbs and culinary arts have helped us get around a lot of plant defense systems, but furanocoumarins can still affect us if we're not careful.

With the energy from the UV radiation in sunlight, furanocoumarins can undergo a chemical reaction and bind to certain bits of DNA inside another creature's cells, messing with the DNA's structure.

利用阳光中紫外线辐射的能量,呋喃香可以发生化学反应, 并与另一生物细胞内的 DNA 位点结合, 从而扰乱 DNA 的结构。
Limes, for instance, have a cocktail of three furanocoumarins that are concentrated in the juice and peel, ready to be released and activated whenever the fruit is bitten—or squeezed into your favorite drink on a beach day.
