Chemoprofiling of Homoeopathic drug Holarrhena antidysenterica L.

Abstract

Background: Chemoprofiling of homoeopathic drug/tincture (HT) represents a comprehensive approach for evaluation of quality, purity, safety and efficacy of HT. This paper reflects the chemoprofiling of Homoeopathic drug Holarrhena antidysentrica L. Objective: The objective of this study is to standardise Holarrhena antidysenterica mother tincture by taking the samples from four different sources: Dr D. P. Rastogi, CRI (H) Noida (A) and three from market (labelled as B, C and D). Materials and Methods: The authentic sample of bark of Holarrhena antidysenterica supplied by the Centre of Medicinal Plants Research in Homoeopathy, Emerald, Tamil Nadu, India was used to prepare the mother tincture (as per the Homoeopathic Pharmacopoeia of India). The solvents used throughout the study, namely, ethanol, high‑pressure liquid chromatography water, cyclohexane, chloromethane and diethylamine, were of analytical grade purity (MERCK Ltd.). Physicochemical properties, ultraviolet (UV) spectroscopy and high‑performance thin‑layer chromatography (HPTLC) chemoprofile of raw drug and mother tinctures were standardised and compared with market samples. Results: The present study reveals the moisture content (14.40%), total ash (4.65%), alcohol (18.0%), water extractive values (16.0%), total solids (1.47%), weight/ml (0.92 g) and alcohol content (60.6%). In UV spectroscopy, λmax values were observed at 228 and 278 nm in HT. HPTLC analysis of in‑house HT (A) and three market samples (B, C, D) was performed by using cyclohexane: chloromethane: diethylamine (7:3:1, v/v/v) as mobile phase. Under UV light (254, 366 nm) and in the presence of visualising agent Dragendroff, bands of active constituent were observed in all the four samples. However, excess amount of active constituents were found in in‑house HT (a) rather than the market samples (B, C and D). Conclusion: The present physicochemical and phytochemical data may be considered as pharmacopoeia standards for the homoeopathic drug Holarrhema antidysentrica L.
