Abstract

Ayurveda is the intangible Cultural Heritage of India and “Sitopaladi churna”, is a renowned Ayurvedic formulation which is recommended to treat the ailment like viral infection of respiratory tract, allergic situations and used as a natural anti-oxidant. The fundamental concerns in quality control of Sitopaladi churna arise due to substitution, omission, adulteration in the ingredients of Siitopaladi churna. A novel method based on Fourier transform infrared technique with attenuated total reflectance facility with a diamond Attenuated total reflectance crystal was used to evaluate samples of Sitopaladi churna. Total 35 different samples including standardized in house samples were studied. For, Fourier transform infrared spectroscopic study transmittance mode was kept to record the spectra devoid of pellets of potassium bromide. Further treatment was given with multi component tools by considering fingerprint region of the spectra. Multivariate analysis was performed by various chemometric methods like Principal component analysis and Hierarchical cluster analysis for further analysis to evaluate the differences in market samples of Sitopaladi churna. The developed method was inexpensive, simple, rapid, precise and stable. Thus, the method can be used as an efficient and practical approach for quality assessment of Sitopaladi churna.

通过衰减全反射快速鉴定 Sitopaladi Churna 样品 – 使用多变量分析的傅里叶变换红外光谱

摘要

阿育吠陀是印度的非物质文化遗产和“Sitopaladi Churna ”,是一种著名的阿育吠陀配方,推荐用于治疗呼吸道病毒感染、过敏情况等疾病,并用作天然抗氧化剂。Sitopaladi Churna 质量控制的基本问题是由于 Sitopaladi Churna 成分中的替代、遗漏和掺假而引起的。一种基于傅里叶变换红外技术的新方法,具有衰减全反射装置和金刚石衰减全反射晶体,用于评估 Sitopaladi churna 样品。研究了总共 35 个不同的样品,包括标准化的内部样品。因为,傅里叶变换红外光谱研究透射率模式被保留以记录没有溴化钾颗粒的光谱。通过考虑光谱的指纹区域,使用多分量工具进行进一步处理。通过主成分分析和层次聚类分析等多种化学计量学方法进行多变量分析,以进行进一步分析,以评估 Sitopaladi Churna 市场样本的差异。所开发的方法价格低廉、简单、快速、精确且稳定。因此,该方法可用作 Sitopaladi Churna 质量评估的有效且实用的方法。
