Mint Oil Distillate Adjuvant for Oral Bioavailability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bioactive substances such as Coenzyme Q10, carotenoids, curcuminoids, and resveratrol have limited bioavailability due to poor solubility and absorption in the gut, limiting their effectiveness in treating chronic diseases like heart disease and cancer.
Innovation Solution
A volatile distillate by-product of mint oil (VDMO) is used as an adjuvant to enhance the bioavailability of these substances by solubilizing them and facilitating their transport across intestinal epithelial cells, utilizing a mixture of nonpolar and polar compounds similar to bile salts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If bioactive substances are administered orally, then they can reach target tissues, but their poor solubility limits absorption and bioavailability
Solution Approach 1:
The patent uses volatile distillate by-product of mint oil (VDMO) as an intermediary substance to enhance the solubility and absorption of poorly bioavailable compounds. VDMO acts as a mediator between the hydrophobic bioactive substances and the aqueous environment of the gut, forming mixed micelles that facilitate transport across intestinal epithelial cells. This resolves the contradiction by introducing a third substance that bridges the solubility gap without requiring modification of the original bioactive compounds.
Solution Approach 2:
The patent changes the physical-chemical parameters of the delivery system by using VDMO to form mixed micelles with bile salts, creating a colloidal structure with specific surface properties that enhance solubility. The micellar structure provides a hydrophobic core for incorporating lipophilic bioactives while maintaining overall water solubility, thus transforming the solubility parameter from poor to adequate for oral absorption.
2Quantity of substance
If low-boiling fractions of mint oil are used as solvents, then solubility of bioactive substances improves, but toxicity concerns arise
Solution Approach 1:
The patent extracts and removes the toxic low-boiling fractions (primarily limonene and other monoterpenes) from the mint oil during the distillation process. The VDMO used as the adjuvant is specifically the higher-boiling fraction that remains after removing these volatile, potentially toxic components. This extraction principle resolves the contradiction by separating the beneficial solubility-enhancing properties from the harmful toxic components.
Solution Approach 2:
The patent converts the previously discarded by-product fraction of mint oil distillation into a beneficial adjuvant. The VDMO, which was originally considered waste or low-value material, is now utilized for its solubility-enhancing properties. This transforms a potentially harmful waste product into a useful therapeutic component, resolving the toxicity concern while maintaining solubility benefits.
3Reliability
If VDMO is used to enhance bioavailability, then absorption of bioactive substances increases, but the complexity of the formulation increases
Solution Approach 1:
The patent employs VDMO which naturally forms mixed micelles with bile salts already present in the intestinal environment. This self-assembling property eliminates the need for complex external formulation systems like liposomes or polymer-based delivery systems. The VDMO-bile salt micelles automatically form in the gut and perform the solubility-enhancing function, reducing formulation complexity while maintaining high absorption efficacy.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
VDMO significantly increases the absorption and serum concentration of CoQ10 and other bioactive compounds, improving their delivery to mitochondria and tissues, thereby enhancing their health benefits.
Implementation Method 1
The VDMO is believed to function in a manner more similar to bile salts than do solutions of pure solvents, and it is believed that the VDMO forms mixed micelles with the bile salts in the gut.
Implementation Method 2
The VDMO possesses beneficial solubility characteristics for poorly bioavailable compositions and acts as an adjuvant to enhance the bioavailability of these substances by solubilizing them.
Implementation Method 3
facilitating their transport across intestinal epithelial cells

AI summary
Disclosed is an adjuvant for improving the bioavailability of bioactive compositions. The adjuvant is prepared from a byproduct of mint flavor production. In vitro and in vivo testing confirms effectiveness. The adjuvant contains a mixture of compounds which is effective to improve the oral bioavailability of a bioactive composition normally having limited absorptivity, and it comprises a mixture of nonpolar compounds and compounds with some polar characteristics. In preferred form the nonpolar compounds comprise compounds selected from a group that includes terpene hydrocarbons and terpene derivatives and the compounds with some polar characteristics comprise compounds selected from a group that includes aldehydes, alcohols and ketones. The preferred compositions will have a ratio of nonpolar compounds and compounds with some polar characteristics is within the range of from 5:1 to 20:1. The adjuvants can enhance delivery of CoQ10 and other bioactive compositions, such as carotenoids (e.g., β-carotene), curcuminoids, lycopene, resveratrol, flavonoids and other phenolic compounds, organosulfur compounds, saponins, sterols, stanols, and mixtures of at least two of these, to the interior cellular environment, including organelles, such as the mitochondria.
