Phytoconstituents assessment and development of standardization protocol for 'Nayopayam Kwatha', a polyherbal Ayurvedic formulation.

ABSTRACT:

Background

Nayopayam kwatha (NK) is a well-known polyherbal formulation widely used to cure respiratory ailments, heart problems, and postnatal difficulties. Literature suggests that so far no standardization protocol was developed for NK to validate its quality and purity.

Objective(s)

To develop a standardization protocol for NK based on the marker phytoconstituents present in the individual herbs of the formulation.

Materials and methods

The roots of bala [Sida cordifolia (B1) and Sida retusa (B2)], seeds of jeeraka (Cuminum cyminum), and rhizomes of nagara (Zingiber officinale) were the ingredients of NK. Since there were two source plants for bala, two sets of NK (NKB1 and NKB2) were prepared in the ratio 3:2:1 as per Vaidya Manorama and 10:1:1 as per Arogyaraksha Kalpadruma along with 1:1:1 as per the general way of Ayurvedic polyherbal decoctions. Both the individual herbs and the kwatha (decoction) prepared were analyzed in terms of pharmacognostical, organoleptic, and physcicochemical parameters as per the standard methods. Phytochemical analysis of the individual herbs resulted in the isolation of major phytoconstituents and the kwatha was quantified in terms of marker compounds with the aid of HPLC.

Results

HPLC quantification suggests that appreciable amount of marker phytoconstituents of individual herbs are present in the kwatha. Thus, the isolated compounds luteolin (C. cyminum), 6-gingerol (Z. officinale), β-sitosterol (S. retusa), and ecdysterone (S.cordifolia) can be used as markers to standardize NK.

Conclusion

Characteristics of NK, as well as its individual drugs, were well-established. The present study of NK with respect to its phytochemistry revealed that the classical drug ratios of the polyherbal formulation are of utmost importance rather than the ingredients in equal proportion. The characterization parameters of individual herbs and kwatha described in this study may serve as a standard reference for quality control analysis of NK and the method developed in this study can be used as a reliable technique for standardization of NK to ensure the purity and quality of raw drugs used.

Project description:BackgroundGuggulutiktaka ghritam is an ayurvedic medicine which has been traditionally used to treat various chronic inflammatory conditions. However, the mechanism of action of the Ayurvedic medication in control of inflammatory conditions has not been clearly evaluated.ObjectiveIn the current study, the effect of the Guggulutiktaka ghritam extract (GTG) on the lipoxygenase pathway and in the production of proinflammatory cytokines involved in the pathogenesis of chronic inflammation was studied.Materials and methodsThe effect of GTG in the production of leukotriene was determined by enzyme inhibition studies on 12- lipoxygenase. The assay was carried out by ferrous oxidation of xylenol orange (FOX assay) and was compared to a positive control nordihydroguaiaretic acid. The effect of GTG on the production of proinflammatory cytokines TNF-α and IL-1β in monocytes were studied. For this, the monocytes were pretreated with various concentrations of GTG and subsequently stimulated with lipopolysaccharide. The cytokines TNF-α and IL-1β produced were quantified by ELISA and the results were compared to positive controls Rolipram and Dexamethasone respectively. The gene expression studies were carried out using qRT-PCR. The IC50 values were calculated and evaluated statistically.ResultsThe result indicates that GTG in comparison to the positive control Nordihydroguaiaretic acid significantly reduced the activity of 12- lipoxygenase. Also, there was significant inhibition in the production of proinflammatory cytokines in LPS stimulated monocytes pretreated with GTG as compared to positive control Rolipram and Dexamethasone. There was significant downregulation of IL-1β gene in LPS stimulated monocytes pretreated with GTG as compared to control. These changes are further supported by Raman spectra obtained for GTG treated and untreated cells.ConclusionThe study revealed that GTG is a leukotriene and cytokine inhibitor. The inhibition in the production of cytokines may be due to the down-regulation of genes for TNF-α and IL-1β. The study provides a scientific validation on the possible anti-inflammatory mechanism of action of this traditionally used medicine. Identification of bioactive molecules would aid in developing newer therapeutics for control of chronic inflammation.
