Objective: To establish a method to identify the different origins of herba Evodia rutaecarpa by IR and provide a new technique for their identification and quality evaluation.
Methods: The herba materials were extracted by chloroform and absolute alcohol, the powder and the extracts of Evodia rutaecarpa were mixed and pelleted with KBr. The slides were detected within 4000 - 400 cm(-1) by FIR spectrophotometry. The Difference of samples was studied.
Results: The infrared spectrums of Evodia rutaecarpa extracted by chloroform were obviously different.
Conclusion: The method can be used to identify and appraise the different origins of herba Evodia rutaecarpa.

Thyroid cancer (TC) is one of the most prevalent endocrine malignancy with a steadily increasing incidence globally. Although standard treatments like thyroidectomy and radioiodine therapy effectively manage most cases of differentiated thyroid cancers (DTC), certain recurrent cases or those involving poorly differentiated thyroid cancers (PDTC) demand more specialized interventions. Follicular thyroid cancer (FTC) is the second most common type of DTC, and frequently metastasizes through the bloodstream to distant sites such as bones and lungs which is a leading cause of metastatic and recurrent DTC and significantly affects survival.

Article Synopsis
- Researchers screened and prepared acetylcholinesterase (AChE) inhibitors from the plant Evodia rutaecarpa, focusing on three key alkaloids: dehydroevodiamine, evodiamine, and rutecarpine.
- They improved extraction methods by combining traditional response surface methodology with a genetic algorithm, and utilized high-speed countercurrent chromatography to isolate these active compounds.
- The study confirmed the structures of these compounds through nuclear magnetic resonance spectroscopy and validated their neuroprotective properties against cell damage, setting the stage for future development of AChE inhibitors.

Chronic inflammation significantly contributes to the progression of osteoarthritis (OA), and an anti-inflammatory small molecule derived from medicinal herbs could be a potential drug candidate for OA. Herein, we investigated the function and mechanism of Evodiamine (EAE), the active ingredient from Evodia rutaecarpa, in chondrocytes and macrophages in vitro and in vivo. The cytotoxicity of EAE was determined using an MTT assay.
