Annatto Extract Compositions, Including Geranyl Geraniols And Methods Of Use
ActiveUS20080031985A1Preventing statin toxicityIncreasing CoQBiocideSenses disorderEnergeticsSide chain
Annatto extract composition (AEC), including cis and trans geranyl geraniols (GG) and tocopherol-free C-5 unsubstituted tocotrienols (T3), increases the de novo synthesis of intermediate isoprenoid and distal protein products, including endogenous coenzyme Q10 (CoQ10), dolichols (DL) and all subsequent GG-prenylated and DL-glycosylated proteins, including GG-porphyrinated hemes. This intermediate and distal product replenishment by AEC reverses maladies of myotoxicity (of both drug and non-drug origins), including maladies that affect the muscle, kidney, eye, GI tract and skin, nerve, blood, and CoQ10-related syndromes of energetics and LDL protection. AEC anabolically increases the endogenous de novo CoQ10 synthesis via GG elongation / prenylation of side-chain and conversely CoQ10 catabolically increases the endogenous de novo GG synthesis via beta-oxidation of CoQ10. Also, such AEC decreases de novo synthesis and increases disposal of triglycerides (TG) in humans via PPAR activation and SREBP deactivation. Such drop in TG by AEC reverses maladies of insulin resistance (IR) and metabolic syndrome (MS), prediabetes, diabetes and diabetes-related cardiovascular diseases (CVD). GG activates PPAR and down regulates SREBP transcription factors. This AEC, containing GG, inhibits cancer growth whether or not GG involvement in protein prenylation is required.

Method for preparing high-purity annatto
InactiveCN101974247AEasy to separate and extractEffective extraction and separationNatural dyesCarboxylic acid esters separation/purificationHigh concentrationImpurity
The invention discloses a method for preparing high-purity annatto. The method comprises the following steps of: adding annatto seeds to an alcohol or acetone aqueous solution; stirring at 30-60 DEG C and separating solid and liquid to obtain an annatto extracting solution; enriching and desorbing the annatto extracting solution through absorption resin; and decompressing, concentrating, crystallizing and drying an obtained desorbing solution to obtain an annatto crystal. In the invention, because macroporous absorption resin is adopted to enrich the annatto, most high-polarity impurities canbe removed, therefore, the clarity and the quality of the extracting solution are improved; a discontinuous gradient desorbing method is adopted in the desorbing process, and a low-concentration alcohol sluicing resin column can be used for removing most polysaccharides and strong-polarity impurities adsorbed by the resin; and then the high-concentration alcohol is used for desorbing to ensure that the desorbing solution quality is greatly improved, which is beneficial to subsequent crystallization. An obtained product has high purity, wherein shown as detection, the content of HPLC (High Performance Liquid Chromatography) is larger than 95 percent, and the yield reaches higher than 80 percent, thus the invention provides a safer technical guarantee for producing officinal grade raw materials, has low extracting cost and is suitable for industrial production.
