INTRODUCTION

Dashmoola Kashaya is classical ayurvedic polyherbal decoction prepared from the roots of the ten medicinal plants collectively known as Dashmoola. Dashmoola Kashaya is traditionally indicated in a wide spectrum of disorders including Fever (Jwara), Respiratory disorders (Shwasa), Cough (Kasa), Inflammatory conditions (Shotha), Abdominal masses (Gulma), Facial palsy (Ardita), Hemiplegia (Pakshaghata), and various musculoskeletal disorders like non-specific low back ache and Sciatica (Gridhrasi). Internally it acts by pacifying aggravated Vata and Kapha by reducing systemic inflammation. Externally Dashmoola decoction is used in procedures such as Parisheka, Nadi sweda and Sthanik basti therapies where it employs local anti-inflammatory and analgesic action (AFI, 2003).

Gas Chromatography-Mass Spectrometry (GC-MS) is a robust and sensitive analytical platform widely employed for qualitative and semi-quantitative identification of volatile and semi-volatile phytochemicals in herbal formulations. The technique enables structural elucidation based on retention time, mass fragmentation patterns and spectral library matching, thereby facilitating quality control, bioactivity correlation and standardization of complex polyherbal preparations.

The medicinal efficacy of Ayurveda formulation is depended on the quality and consistency of the ingredients used (Nhawkar et al., 2014). There is a need for analysis of herbal formulation through modern pharmacological analytical technic to establish its therapeutic effect. The present study aims to analyse the physiochemical composition of freshly prepared Dashmoola Kashaya using GC-MS and to correlate the identified metabolites with their biological activities. Such analytical validation may contribute to evidence-based integration of classical formulations into contemporary clinical practice.

RESULTS

Results of Organoleptic and Physicochemical Analysis of Raw Drugs

The sample had a brownish colour, a distinct taste, and a distinctive odour according to conventional quality characteristics (Table 2). There was no evidence of extraneous material. It was discovered that the physicochemical characteristics fell within the limits of in-house specifications mentioned in Table : Analysis of Raw Drugs used in Dashmoola Kashaya Choorna. Low moisture is shown by the drying loss (4.99% W/W), which is significantly less than the maximum limit (NMT 10% W/W). The total ash measurement (2.90% W/W) indicates few inorganic contaminants and is within acceptable limits (NMT 5% W/W). The alcohol-soluble extractive value (12.05% W/W) satisfies the minimal criterion (NLT 12% W/W), whereas the acid-insoluble ash was 0% W/W (Table 2).

DISCUSSION

Discussion on Physicochemical Analysis

Physicochemical (Table 2) analysis can be used for identification and assessing herbal mixture. The formulation has brownish color, distinctive flavor and odor which anticipates its quality. The coarse particle size was appropriate for the preparation of the formulations like Kashaya.

The loss on drying (4.99% w/w) was within the standard limit (10%w/w), suggesting that the sample had a low moisture content, this is important for preventing microbial development, enzymatic degeneration, and formulation deterioration during storage.

Standard acceptable total ash value (2.90% w/w) and acid-insoluble ash (0% w/w) indicates that the formulation has minimal impurities such as, siliceous elements or mineral matter, demonstrating an excellent and purity of the raw material utilised in the preparation.

The alcohol-soluble extractive value (12.05% w/w) which is less than normal (12% w/w) suggest presence of alcohol-soluble phytoconstituents such as flavonoids, alkaloids, phenolic compounds and other active components.

DISCUSSION

Discussion on GC-MS Analysis

9,12-Octadecadienoyl chloride, (Z, Z)-

9,12-octadecadienoyl chloride (Z, Z) (Table 3 and Figure 2) is a linoleic derivative with antimicrobial and anti-quorum sensing properties (Singh and Singh, 2019). Such chemicals inhibit bacterial communication (QS pathways), lowering biofilm formation and virulence expression. The fatty acids from this class exhibits membrane modulating action, which contribute to antibacterial activity (Begum et al., 2025).

Figure 2: 9,12-Octadecadienoyl chloride, (Z, Z)-.

(+)-Sesamin

Sesamin, (Table 3 and Figure 3) a main compound found in Sesamum indicum, has potent antioxidant, anti-inflammatory, hypolipidemic and cardioprotective properties. It regulates NF-κB signalling, improves hepatic fatty acid oxidation, and lowers oxidative stress markers. Some clinical and experimental studies demonstrate better lipid profiles and Cytokine inhibition and endothelial protection property. Sesamin also shows hepatoprotective and neuroprotective effects through ROS scavenging and cytokine modulation (Dalibalta et al., 2020).

Figure 3: (+)-Sesamin.

Cholest-5-en-3-ol (3β)-, tetra decanoate

Sterol metabolism (Table 3) is related to this cholesterol ester derivative. Cholesterol metabolites affect inflammatory signalling pathway and glucose homeostasis. Sterol derivative studies have shown that they can modulate lipid metabolism and may have anti-inflammatory properties (Maganga et al., 2024).

2H-Pyran, 2-(7-heptadecynyloxy) tetrahydro-

Pyran derivatives, (Table 3) identified in phytochemical investigations of Erythrina variegata which have antibacterial and antioxidant activity (Amutha et al., 2014). These heterocyclic compounds have membrane-protective and radical scavenging characteristics. Anti-inflammatory and cytoprotective effects implied by experimental models (Muthukrishnan et al., 2016). Their biological function is often attributed to oxygen-containing ring structures.

R-6-Methoxy-2,8-dimethyl-2-((4R,8R)-4,8,12-trimethyltridecyl) chroman

This is a chroman derivative (Table 3), shares structural similarities with tocopherol analogues, which are substances that resemble vitamin E. Research emphasizes the potential of antioxidants and enzyme inhibitors, such as scavenging free radicals and preventing lipid peroxidation. It exhibits anti-aging property, cryoprotection, and potential anti-inflammatory effects (Velmani et al., 2025).

Undec-10-ynoic acid, undecyl ester

This molecule, derived from 10-undecynoic acid (Table 3), has potent antibacterial and antibiofilm properties, particularly against oral Streptococcus species. It acts by inhibiting microbial adherence and biofilm development (Goc et al., 2019). Antifungal and topical antimicrobial treatments contain comparable chemicals.

Oleic acid

It is monounsaturated fatty acid (Table 3) in plant. It improves the gut-liver axis and controls lipid metabolism through modulating SCD1. Some studies established its insulin-sensitizing, cardioprotective and anti-inflammatory activities. It promotes endothelial health and lowers LDL oxidation (Sener et al., 1999).

15-Tetracosenoic acid, (Z)-, TMS derivative

It is a long chain unsaturated fatty acid (Table 3), which can reduce inflammation by modulating the NF-κB pathway and suppressing cytokine production. Fatty acid derivatives can lower inflammatory mediators and oxidative damage (Li et al., 2025). They may also help maintain membrane structural integrity.

3-O-Methyl-d-glucose

A glucose analogue (Table 3) was investigated for transport and metabolic pathway studies. It is useful for assessing glucose absorption pathways involving GLUT transporters (Jay et al., 2018). While not directly therapeutic, it provides information about carbohydrate metabolism and cellular glucose regulation.

9,12-Octadecadienoic acid, methyl ester, (E, E)-

A methyl ester of linoleic acid (Table 3) with antioxidant and anti-inflammatory properties. Studies show that free radicals are scavenged and lipid peroxidation is inhibited (Muzahid et al., 2022). It may help to protect the cardiovascular system.

15-Octadecenoic acid, methyl ester

It is said to be an anti-inflammatory chemical found in plant extracts that controls inflammatory mediators and lowers cytokine expression (Table 3) (Dong et al., 2000). Fatty acid methyl esters frequently exhibit antioxidant and membrane-stabilizing effects.

(2-Cyclohexylpropyl)(methyl)amine

Plant extracts have been reported to have an anti-inflammatory chemical that controls inflammatory mediators and lowers cytokine expression (Table 3) (National Centre for Biotechnology Information, 2026) Methyl esters of fatty acids frequently exhibit membrane-stabilizing and antioxidant characteristics.

3,7-Dimethyl-6-nonen-1-ol acetate

A terpenoid ester (Table 3) commonly identified in plant essential oils. Terpenoids show antimicrobial, anti-inflammatory, and antioxidant actions. They may also contribute to aroma-therapeutic and mild cytoprotective effects (Salisu et al., 2025).

9-Octadecen-12-ynoic acid, methyl ester

9-Octadecen-12-ynoic acid (Table 3 and Figure 4), methyl ester is showing its ability to cross the BBB and potentially reach the central nervous system. Based on the pharmacokinetic parameters 9-Octadecen-12-ynoic acid, methyl ester was selected as the best choices due to their BBB penetration ability, superior absorption profile and permeability (Ilyas et al., 2025).

Figure 4: 9-Octadecen-12-ynoic acid, methyl ester.

CONCLUSION
