The objective of the study was to evaluate the effect of detoxification process on plumbagin (PG) from the Plumbago zeylanica L. roots in marketed samples. It involved procurement of market samples from five states of India viz. Andhra Pradesh, Gujarat, Maharashtra, Madhya Pradesh and Punjab. The roots were purified in lime water (LW) as mentioned in Ayurveda. Reverse Phase Ultra-Flow Liquid Chromatography method was validated for identification of PG in unprocessed and processed roots and in the media (LW) used for purification after processing. The data was statistically analyzed by Analysis of Variance (ANOVA) and tested for significance by the Dunnett multiple comparison test. Results were expressed as mean ± SD mg/g dry weight of extract. The study indicated that the PG was reduced quantitatively after processing, while the amount of PG found in the LW was observed to be increased, indicating the leaching of PG during the purification process. In conclusion, the detoxification process eliminates PG from its roots and discloses the leaching effect in the media for the first time.","PeriodicalId":15430,"journal":{"name":"Journal of chromatographic science","volume":" ","pages":""},"PeriodicalIF":1.5,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142140263","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ethyl alcohol, isopropyl alcohol and sulfuric acids were used in the manufacturing process of ABS. Therefore, there is a possibility to form respective sulfate impurities, i.e., EtSs and IprSs. Hence, a control strategy is required for EtS and IprS contents in ABS. Chromatographic separation of EtS and IprS contents in Abacavir sulfate was achieved on Metrosep A Supp 10 (250 mm × 4.0 mm) column and particles of 4.6 μm size. The mobile phase consists of buffer (3.2 mM Sodium carbonate and 1.0 mM of sodium bicarbonate) and acetonitrile in the ratio of 90:10 (v/v) with the flow rate of 0.6 mL min-1 by applying 30°C column oven temperature. The analytes were monitored by conductometric detector. The performance of the method was assessed by evaluating the specificity, linearity, sensitivity, precision, robustness and accuracy experiments. The limit of detection and limit of quantification values for EtS were 0.3 and 0.8 μg mL-1 and for IprS were 0.3 and 0.8 μg mL-1, respectively. The correlation co-efficient value of linearity experiment was 0.9999 for EtS, 0.9998 for IprS. The average recovery for EtS was 98.7% and for IprS was 100.9%. The method is robust for EtS and IprS contents and also specific from other common anions, i.e., chloride, bromide, nitrate, sulfate, methyl sulfate and methanesulfonic acids.
