Freshly-used crude drugs have unique functions and advantages in TCM practice of treating diseases. Jinlong Capsule is a patent traditional Chinese medicine product effective for treatment of hepatocarcinoma, and fresh Jinqian Baihua She (JBS, the body of juvenile Bungarus multicinctus) is one of its important ingredients. The emergence of counterfeit fresh JBS, often identified as dried JBS with almost identical appearance, poses a difficult problem in the quality control of the product.

Introduction: Paclitaxel (Tax) is a diterpene alkaloid isolated from Taxus species and has proved clinically effective in treating a number of malignancies. Current quantitative analytical methods for Tax such as high-performance liquid chromatography (HPLC) often involve complicated sample preparation procedures with low recovery rates.

Objective: To establish a rapid and sensitive time-resolved fluoroimmunoassay (TRFIA) for measuring Tax in Taxus materials with convenient sample preparation and a high recovery rate.

Article Synopsis
  • Ophiocordyceps sinensis, known as DongChongXiaCao (DCXC), is a highly valued traditional Chinese medicine that has been used since the 15th century and is difficult to harvest due to its rare growth at high altitudes on the Qinghai-Tibetan Plateau.
  • The rising prices of DCXC have led to increased harvesting activities by migrants, posing risks to the fragile grassland ecosystems.
  • The article discusses the need for artificial cultivation of DCXC, detailing methods for breeding moth larvae (genus Hepialus) and isolating the fungi, while also exploring potential biotechnological advancements to support sustainable practices and environmental conservation.

This article documents the addition of 83 microsatellite marker loci and 96 pairs of single-nucleotide polymorphism (SNP) sequencing primers to the Molecular Ecology Resources Database. Loci were developed for the following species: Bembidion lampros, Inimicus japonicus, Lymnaea stagnalis, Panopea abbreviata, Pentadesma butyracea, Sycoscapter hirticola and Thanatephorus cucumeris (anamorph: Rhizoctonia solani). These loci were cross-tested on the following species: Pentadesma grandifolia and Pentadesma reyndersii.

Premise Of The Study: To investigate genetic structure of the pollinator and, indirectly, gene flow in its plant host, Blastophaga javana microsatellite primers were developed.

Methods And Results: Ten polymorphic microsatellite loci were developed using the Fast Isolation by AFLP of Sequences Containing (FIASCO) repeats protocol. Numbers of alleles per locus ranged from 2 to 19, with observed and expected heterozygosities ranging from 0.
