gamma-Oryzanol TCI O0172

gamma-Oryzanol is a mixture of ferulic acid esters formed with various sterols and triterpene alcohols, including cycloartenol, 24-methylenecycloartanol, campesterol, and beta-sitosterol. The mixture is obtained mainly from rice bran oil. TCI lists this material under Crude Medicine Ingredients for Research and Experimental Use, a category of natural medicinal raw materials intended for research and experimental work. In the laboratory, gamma-oryzanol serves as an analytical standard, a test compound in bioactivity studies, and a research material for nutraceutical development.

Researchers choose gamma-oryzanol because the ferulic acid portion of each ester carries a phenolic group, which gives the material its antioxidant activity. The sterol portion makes the molecule lipophilic, so it dissolves well in oils and organic solvents. Together, these features make it a subject of research into cholesterol-lowering effects, anti-inflammatory activity, and protection of skin against free radicals. Because it is a natural mixture and not a single compound, gamma-oryzanol is also useful for developing chromatographic methods that separate and identify each of its ester components.

Indonesia is one of the world's largest rice producers, and rice bran is widely available as a by-product. This makes gamma-oryzanol especially relevant to Indonesian technology laboratories that study the value of local agricultural materials. University research groups, nutraceutical developers, and analytical laboratories can use it as a reference material when they characterize rice bran oil, test antioxidant activity, or build chromatographic methods to profile the ester components in natural extracts.

• Analytical reference standard: gamma-oryzanol gives a defined reference for identifying and comparing ferulic acid ester components when analyzing rice bran oil and related natural extracts.
• Chromatographic method development: because it is a natural mixture of several sterol and triterpene alcohol esters, it is a good test material for methods that separate and identify each individual ester component.
• Antioxidant activity studies: the phenolic group from its ferulic acid portion gives antioxidant activity, so it works well as a test compound in free radical and oxidation assays.
• Nutraceutical research: its connection to cholesterol-lowering and anti-inflammatory research makes it a relevant material for early-stage evaluation of functional food and supplement ingredients.
• Skin protection and formulation research: its lipophilic sterol portion and antioxidant character suit studies on protecting skin from free radicals in oil-based and organic solvent systems.

• Composition: mixture of ferulic acid esters of sterols and triterpene alcohols, obtained mainly from rice bran oil

Store gamma-oryzanol in its original, tightly closed container in a cool, dry, well-ventilated place. Keep it away from direct sunlight, heat sources, and strong oxidizing agents, since its phenolic antioxidant groups can degrade over time when exposed to air and light. Always follow the specific storage conditions on the TCI label and Safety Data Sheet. Standard laboratory precautions apply: wear gloves, safety glasses, and a lab coat, avoid creating or breathing dust, and handle open containers in a ventilated area. Reseal the container right after use to limit contact with moisture and air. This material is for research and experimental use only.
