The present study aims to investigate the correlation between irritant toxicity variation and lectin content variation during the processing of Pinelliae Rhizoma products and to explore the feasibility of Western blot as a method for the detection of lectin. We processed Pinelliae Rhizoma Praeparatum Cum Alumine, Pinelliae Rhizoma Praeparatum, and Pinelliae Rhizoma Praeparatumcum Zingibere et Alumine to different degrees and then analyzed their irritant toxicity via Draize rabbit eye test. Western blot was employed to determine the lectin content in Pinelliae Rhizoma products processed with different methods. The correlation between toxicity variation and lectin content variation was then analyzed. Different decoction pieces of Pinelliae Rhizoma were collected for the determination of lectin content. The three processed products of Pinelliae Rhizoma showed gradually decreased toxicity and lectin content as the processing continued. The decreasing trend of lectin content was consistent with that of irritant toxicity during processing, which indicated that the change in lectin content could reflect the trend of irritant toxicity. No band of lectin appeared in the Western blot of processed products of Pinelliae Rhizoma, which suggested that western blotting can be used for the detection of toxic lectin in the processed products of Pinelliae Rhizoma. Lectin should not be detected in the Pinelliae Rhizoma products processed according to the methods in the Chinese Pharmacopoeia.

Based on the latent structure model and association rule analysis, the regularity of prescription for hyperlipidemia comorbid with hypertension was explored, and traditional Chinese medicine(TCM) pattern type was speculated to provide a reference for clinical pattern differentiation and treatment, and guideline establishment. The literature on the treatment of hyperlipidemia comorbid with hypertension by TCM was systematically searched on CNKI, Wanfang, VIP, and SinoMed academic platforms. The relevant information was extracted and a database was established using Microsoft Excel 2019.

Pinelliae Rhizoma, renowned for its medicinal benefits against cough, insomnia and inflammation, is frequently utilized in botanical dietary supplements and herbal products. However, due to high demand, there is a risk of adulteration. This study introduced Direct-Loop-Mediated Isothermal Amplification (Direct-LAMP), a rapid colorimetric technique, for distinguishing Pinelliae Rhizoma from its primary adulterant, Rhizoma Typhonii Flagelliformis.

Pinelliae Rhizoma is a key ingredient in botanical supplements and is often adulterated by Rhizoma Pinelliae Pedatisectae, which is similar in appearance but less expensive. Accurate identification of these materials is crucial for both scientific and commercial purposes. Traditional morphological identification relies heavily on expert experience and is subjective, while chemical analysis and molecular biological identification are typically time consuming and labor intensive.

Pinelliae Rhizoma (PR), a highly esteemed traditional Chinese medicinal herb, is widely applied in clinical settings due to its diverse pharmacological effects, including antitussive, expectorant, antiemetic, sedative-hypnotic, and antitumor activities. exhibits morphological variation in its leaves, with types resembling peach, bamboo, and willow leaves. However, the chemical composition differences among the corresponding rhizomes of these leaf phenotypes remain unelucidated.
