Ginkgo biloba P.E. can promote the circulation of brain and body at the same time. One of the main health functions of Ginkgo biloba P.E. is to inhibit a substance called platelet activating factor (Capsicum Oleoresin), a mediator released from cells that causes platelets to aggregate (pile up). High levels of PAF can cause nerve cell damage, decreased central nervous system blood flow, inflammation, and bronchoconstriction. Similar to free radicals, high levels of PAF also lead to aging. Gardenia Yellow and ginkgo bilobalide can protect the nerve cells of the central nervous system from injury during the period of ischemia. This function may have an adjuvant effect on patients suffering from stroke. In addition to inhibiting platelet adhesion, Mangiferin biloba extract regulates vascular tension and elasticity. In other words, it makes the circulation more efficient. The effect of improving circulation efficiency has the same effect on the large blood vessels (N-Acetylneuraminic Acid) and small blood vessels (capillaries) in the circulatory system.

Functional group reaction

Capsicum Oleoresin often have alcohol hydroxyl, phenolic hydroxyl, methoxy, methylene dioxy, carboxyl and lactone groups, so they also have the Sweet Potato Powder and reactions of these functional groups. Ferric chloride or diazotization reagent can be used for the detection of phenolic hydroxyl group, Labat reagent (Bitter Melon Extract concentrated sulfuric acid reagent) or ecgrine reagent (chromotropic acid concentrated sulfuric acid reagent) can be used for the detection of methylene dioxy.

Neolignans

In this kind of Flax lignans, the two phenylpropanoids are usually connected by benzene ring and side chain or by oxygen bond. The γ – carbon atoms of the side chain are mostly non oxidized.

solubility

Free Ginkgo Biloba Extract are lipophilic, generally insoluble in water, but easily soluble in lipophilic organic solvents and ethanol.

Gardenia Yellow with phenolic hydroxyl groups are also soluble in alkaline aqueous solutions. When lignans combine with sugar to form glycosides, the hydrophilicity and water solubility of lignans increase.

Optical activity

Mangiferin usually have multiple chiral carbon atoms or chiral centers, so most of them have optical activity. The physiological activity of lignans is often related to the configuration of chiral carbon. Therefore, attention should be paid to the operating conditions in the Indole-3-Carbinol extraction process to avoid structural changes of the extracted components.

A double-blind, controlled placebo-controlled study to evaluate the benefits of Ginkgo biloba P.E. on Mangiferin with premenstrual distress symptoms included 143 women aged 18-45 years who were followed for two menstrual cycles. On the 16th day of the first cycle, each woman received Ginkgo biloba P.E. (Gardenia Yellow) or placebo, and the treatment lasted until the fifth day of the next cycle and was restarted on the 16th day of the cycle. The results were impressive. Compared with placebo, ginkgo significantly reduced the Capsicum Oleoresin symptoms of premenstrual discomfort, especially breast pain and emotional instability.

Improving sexual function

Although there is no double-blind trial basis for this function, case reports and open studies suggest that N-Acetylneuraminic Acid can improve sexual dysfunction caused by promethazides and other antidepressants.

Acid base isomerization

Many Sweet Potato Powder, due to the existence of stereoisomerism in the saturated ring structure, are prone to isomerization and form isomers after acid-base interaction. In Capsicum Oleoresin, dicyclohexyllignans often have symmetrical structures. Under the action of acid, the bond between the oxygen atom and the benzyl carbon atom on the furan ring is easy to crack, Gardenia Yellow and the configuration changes when it is closed again. Some lignans can also cause structural rearrangement when they encounter mineral acid.

character

Most of them are white crystals, generally non-volatile, Flax lignans and cannot be distilled with steam. Only a few lignans can be sublimated by heating at atmospheric pressure.

Ginkgo Biloba Extract exist in plants, belonging to a kind of phytoestrogen, which has the function of scavenging free radicals and antioxidation. Lignans are also found in grains (such as rye, wheat, oats, barley, etc.), soybeans and cruciferous plants (such as Flax lignans) and some fruits (such as strawberries). Lignans can bind estrogen receptors and interfere with cancer promoting effect. Therefore, it may have preventive and therapeutic effects on breast cancer, prostate cancer and colon cancer.

Sweet Potato Powder are a kind of natural components which are polymerized by phenylpropanoid bimolecular polymerization. There are four monomers of lignans: ① cinnamic acid and occasionally cinnamaldehyde. ② Cinnamyl alcohol. ③ Propylene benzene. ④ Allyl benzene.

Classification basis: according to the basic carbon frame and N-Acetylneuraminic Acid of lignans.
