Production of Organic Acids

Production of Organic Acids

Lactic acid, an important organic acid extensively applied in food, pharmaceutical, and biodegradable polymer industries, is primarily produced via microbial fermentation. This method is favored over chemical synthesis due to its environmental sustainability and capacity for enantiomerically pure product formation. Among various microbial processes, the fermentation of starch-based substrates stands out due to the abundance and renewability of raw materials like corn and potatoes.Hydrolysis of...

Area of Science:

Phytochemistry
Traditional Chinese Medicine
Analytical Chemistry

Context:

Atractylodes macrocephalae rhizoma is a vital herb in Traditional Chinese Medicine.
Understanding its processing effects on active compounds is crucial for quality control and therapeutic optimization.
Traditional processing methods aim to alter chemical constituents for improved efficacy or reduced toxicity.

Purpose:

To investigate the changes in main active compositions of Atractylodes macrocephalae rhizoma before and after processing.
To explore the underlying processing principle of Atractylodes macrocephalae rhizoma.

Summary:

High-Performance Liquid Chromatography (HPLC) was used to quantify atractylon, atractylenolides I, II, III, and total volatile oil in differently processed samples.
Processing significantly decreased atractylon content, with the lowest observed in samples stir-fried with dirt (reduced by 25.4%).
Conversely, atractylenolides I and III increased substantially, particularly in samples stir-fried with bran, while atractylenolide II showed a slight increase. Total volatile oil content was significantly reduced post-processing.

Impact:

Processing transforms atractylon into atractylenolides I, II, and III, potentially enhancing the overall therapeutic effectiveness of Atractylodes macrocephalae rhizoma.
The study provides valuable insights into the chemical basis of traditional processing techniques for this important medicinal herb.
Findings can inform standardized processing protocols to ensure consistent quality and maximize the medicinal benefits of Atractylodes macrocephalae rhizoma.
