about Naringin

Naringin is a flavanone-7-O-glycoside between the flavanone Naringenin and the disaccharide neohesperidose. The flavonoids naringenin and hesperetin, which form the aglycones of naringin and hesperidin, occur naturally in citrus fruits, especially in grapefruit, where naringin is responsible for the fruit's bitter taste. In commercial grapefruit juice production, the enzyme naringinase can be used to remove the bitterness created by naringin. In humans the naringin is metabolized to the flavanone naringenin.
The chemical formula of the compound is C27H32O14. It has a molecular weight of 580.53 and in its purest form, the compound appears as a yellow powder. Chemically, it is a conjugate of a sugar molecule and naringenin, which is another flavonoid present in grapefruit.
Generally, flavonoids protect cells from molecules that contain reactive oxygen atoms, commonly called free radicals. Usually, flavonoids reduce the damaging effects of free radicals by stimulating the production of glutathione, which is a strong anti-oxidant. Flavonoids can also increase the effectiveness of vitamin C as an anti-oxidant. In addition, flavonoids play a role in inflammation control by moderating certain cells of the immune system. They can also inhibit the activity of certain types of viruses, including the herpes simplex virus.

Introduction of Geniposide

Geniposide is an iridoid glycoside with a variety of biological activities including neuroprotective, anti-diabetic, antiproliferative, and antioxidative activity. Geniposide has been shown to regulate Nrf2 translocation and upregulate downstream antioxidant protein HO-1 expression through the PI3K/Akt signaling pathway, which may account for its neuroprotective and antioxidative activity. Glucagon-like peptide 1 (GLP-1) receptor may also play a critical role in geniposide induced HO-1 expression.

Cyclovirobuxine D is an anti-atrial fibrillating agent

C26H46N2O, or also known as cyclovirobuxine D, has for the first time been isolated from Buxus papilosa. It has a steroid nucleus in trans/cis/trans configuration. Two of the three cyclohexane rings adopt half-chair conformations and the third ring, with an equatorially attached methylamino substituent, is in a chair conformation. The cyclopentane ring has a half-chair conformation and the N-methylaminoethane group is equatorially attached to it. N-HO and C-HN interactions are observed in the molecular structure and the crystal structure is stabilized by van der Waals interactions
Cyclovirobuxine D is an active compound extracted from Buxus microphylla, which has been used for treating acute myocardial ischemia in China.It significantly reduced the infarct size induced by ligating the coronary artery in rats, and the effect was almost abolished by glibenclamide, a blocker of ATP sensitive potassium channel, but it was not influenced by cyclooxygenase-2 inhibitor celecoxib or estrogen receptor antagonist tamoxifen.
