Discrimination of Baphicacanthis Cusiae Rhizoma et radix and its adulterant species and establishment of an assay method for quality control.

Background: Baphicacanthis Cusiae Rhizoma et Radix, commonly known as Nan-Ban-Lan-Gen (NBLG), is an essential traditional Chinese medicine that possesses diverse bioactivities, particularly noteworthy for its antiviral properties. Although NBLG has been listed in the Chinese Pharmacopoeia as an independent Chinese medicine, the establishment of a comprehensive quality standard for NBLG remains elusive. The absence of assay for marker compound in its quality standards has led to the lack of corresponding quality control measures for NBLG-containing preparations, and its discrimination from adulterant species in the market which thereby can significantly impact the efficacy and safety of NBLG-containing products.

Study on triterpenoic acids distribution in Ganoderma mushrooms by automatic multiple development high performance thin layer chromatographic fingerprint analysis.

Ganoderma--"Lingzhi" in Chinese--is one of the superior Chinese tonic materia medicas in China, Japan, and Korea. Two species, Ganoderma lucidum (Red Lingzhi) and G. sinense (Purple Lingzhi), have been included in the Chinese Pharmacopoeia since its 2000 Edition.

Chemical pattern-aided classification to simplify the intricacy of morphological taxonomy of Epimedium species using chromatographic fingerprinting.

Epimedium herb (Yinyanghuo), one of the popular Chinese materia medica, is a multiple species colony of Epimedium genus belonging to Berberidaceae. There are five species of Epimedium that have been officially adopted in Chinese Pharmacopoeia under the same crude drug name 'Yinyanghuo' comprising Epimedium brevicornu, E. koreanum, E.

Study of the destructive effect to inherent quality of Angelicae dahuricae radix (Baizhi) by sulfur-fumigated process using chromatographic fingerprinting analysis.

The after-harvesting sun-dried process of Angelicae dahuricae radix (Chinese name: Baizhi) was previously the traditional treatment for commodity. Over recent decades the natural drying process for some fleshy roots or rhizomes of Chinese materia medica has been replaced by sulfur-fumigation for curtailing the drying duration and pest control. We used high performance liquid chromatography (HPLC) and high performance thin-layer chromatography (HPTLC) fingerprinting analysis to investigate the potential damaging effect of the sulfur-fumigating process.
