“…The existing available methods for assaying TCP are high-performance liquid chromatography (HPLC), microbiological assay and liquid chromatography-mass spectrometry. [6][7][8] Among them, HPLC is the main measurement method for TCP because of its high separation e±ciency and good selectivity. However, these methods involve a tedious variety of reagents or lengthy run times, which are unsuitable for rapid measurement of TCP in the production process or in blood.…”

Teicoplanin (TCP) is an important lipoglycopeptide antibiotic produced by fermenting Actinoplanes teichomyceticus. The change in TCP concentration is important to measure in the fermentation process. In this study, a reagent-free and rapid quanti¯cation method for TCP in the TCP-Tris-HCl mixture samples was developed using near-infrared (NIR) spectroscopy by focusing our attention on the fermentation process for TCP. The absorbance optimization (AO) partial least squares (PLS) was proposed and integrated with the moving window (MW) PLS, which is called AO-MW-PLS method, to select appropriate wavebands. A model set that includes various wavebands that were equivalent to the optimal AO-MW-PLS waveband was proposed based on statistical considerations. The public region of all equivalent wavebands was just one of the equivalent wavebands. The obtained public regions were 1540-1868 nm for TCP and 1114-1310 nm for Tris. The root-mean-square error and correlation coe±cient for leave-oneout cross validation were 0.046 mg mL À1 and 0.9998 mg mL À1 for TCP, and 0.235 mg mL À1 and 0.9986 mg mL À1 for Tris, respectively. All the models achieved highly accurate prediction e®ects, and the selected wavebands provided valuable references for designing specialized spectrometers. This study provided a valuable reference for further application of the proposed methods to TCP fermentation broth and to other spectroscopic analysis¯elds.

“…The use of different UV wavelengths, from 220 nm to 254 nm 4,5,12-14 , does not transcend on the comparative results. Some authors 13,14,28 have assumed uniform recoveries and response factors for all the analytes. Nevertheless, others 12 have corrected the differences in molecular weights between A3 and A2, being followed by the pharmacopoeias 4,5 .…”

“…[7][8][9][10][11][12][13][14][15][16] However, microbiological assays and immunoassays are labour intensive and time consuming, and chromatographic methods for this drug showed a high retention time. Although teicoplanin has been studied in terms of therapeutic activity and commercialized, there is a nonofficial pharmacopoeial monograph for its quantification using HPLC and there are no studies describing HPLC quantitation methods of this drug in injectable forms.…”

A sensitive, precise and specific high performance liquid chromatographic method was developed for the assay of teicoplanin in injectable pharmaceutical form. Analytical parameters were studied according to the International Conference on Harmonization (ICH). The method validation parameters yielded good results and included the range, linearity, precision, accuracy, specificity and recovery. The HPLC separation was carried out by reversed phase chromatography on a Waters symmetry C 18 column (250 Â 4.6 mm id, 5 mm particle size) with a phase composed of acetonitrile : methanol (50 : 50, v/v), pumped isocratically at a flow rate of 1.0 mL min À1. The effluent was monitored at 279 nm. The developed HPLC method to determine lyophilized teicoplanin can be used to evaluate the quality of regular production samples.
