Haplanthodes tentaculatus (L.) R. B. Majumdar, an endemic plant of the Acanthaceae family found exclusively in India, has long been utilized in traditional medicine for its healing acceleration and stamina-boosting properties. However, there is limited knowledge about its phytochemical composition and its potential medicinal significance. To address this gap, GC-MS analysis was conducted to unveil the phytochemical profile of H. tentaculatus. Moslosooflavone, Squalene, D-Allose, and Phytol were identified as prominent phytoconstituents. These compounds possess known biological activities and are likely responsible for the plant's medicinal properties. This work illustrates the therapeutic capabilities of H. tentaculatus and provides a basis for future investigation into its pharmacological uses. Harnessing the rich phytochemical repertoire of H. tentaculatus may lead to the development of novel drugs and therapeutic interventions. Future study should prioritise on elucidating the mechanisms of action and clinical efficacy of these phytoconstituents to facilitate their integration into evidence-based healthcare practices.

Introduction
Plants have played a significant role in medicine since ancient times.1 Ayurveda, which has been practiced in India since its inception, remains the most widely recognized and trusted form of traditional medicine.2,3 One of the key advantages of using Ayurvedic plants is their minimal side effects, leading to the rapid development of plant-based medicines.4Haplanthodes tentaculatus, or H. tentaculatus, is a flowering plant in the Acanthaceae family, Lamiales order, and Magnoliopsida class. It features white flowers and is also recognized as Haplanthodes tentaculata. Regionally, it’s referred to as “vhadlem kalem kiraytem.” Despite an exhaustive literature review, comprehensive documentation of H. tentaculatus remains incomplete.5,6 Therefore, the aim of this study was to utilize the analytical process of GC-MS (Gas Chromatography-Mass Spectrometry) to identify and isolate biologically active phytocomponents from H. tentaculatus.7 Preliminary research has already been conducted to explore its phytochemical and physicochemical properties. However, more extensive phytochemical investigations were necessary to assess the plant’s quality for potential therapeutic use. While chromatographic fingerprinting is commonly employed as a quality control technique, it does not provide a comprehensive phytochemical profile of the plant.8–10 Consequently, the utilization of GC-MS analysis for different extracts of H. tentaculatus was deemed advantageous.11 This method not only facilitates detailed phytochemical profiling but also aids in the identification of specific phytoconstituents. Motivated by the desire to explore the pharmacological efficacy of plants, we embarked on this research endeavour to uncover the potential applications of H. tentaculatus. By investigating its pharmacogenetic quality parameters and conducting in-depth phytochemical studies, we aimed to discover the therapeutic potential of this herbal species.
Materials and Methods
Collection of plant material: The plant was collected from Gorai Road Bhayandar, Maharashtra, India. The plant material in the form of an herbarium was authenticated and identified by Blatter Herbarium in St. Xavier’s College, Mumbai, India. Specimen matches with the herbarium specimen number 21599 of H. Santapau.
Plant Processing and Extraction
The aerial portion of the plant was collected, rinsed with purified water and shade dried for a few days until it dried completely. It was pulverized in a grinder with small pieces. It is an important step for identifying the plant phytochemical profile. Different methods of extraction were used to get maximum extract. Maceration and Sonication Extraction. The solvents methanol, acetone, and n-hexane were used for extraction in order to determine the phytochemical components.
5 grams of pulverized plant material was added to 100 ml of methanol, as was done with acetone and n-hexane. Individually cold maceration of the extract was carried out for 3 days and then used for GC-MS analysis. 5 grams of plant material were added to 100 ml of solvent. The extraction process lasted for 30 minutes, which included 5 minutes of sonication using an Ultrasonic Bath Sonicator (GSL-200H), with a 1-minute hold. The extract obtained will be used for GC-MS examination in further studies.

Discussion
The GC-MS analysis of Haplanthodes tentaculatus revealed significant insights into its phytochemical composition, underlining its potential for therapeutic applications. The physicochemical parameters, as shown in Table 1, including the total ash value, acid insoluble ash value, and moisture content suggest that the plant material has retained its integrity with minimal degradation, which is crucial for the extraction of bioactive compounds.
The qualitative phytochemical tests detailed in Table 2 demonstrated the absence of alkaloids, carbohydrates, glycosides, and cardiac glycosides across all extracts, pointing towards a unique phytochemical profile tailored towards specific biological activities. This specificity may enhance the plant’s value in developing targeted therapeutic agents with minimal side effects.
The phytochemical profiles derived from different extraction methods, as illustrated in Tables 3 to 8 and depicted in Figures 1 to 6, provide: Chromatogram of macerated and sonication Haplanthodes tentaculatus in Methanol, acetone, and n-hexane, detailing the peak representations of specific compounds. Figure created by the author using data from GC-MS analysis conducted on April 2023. Notably, compounds such as flavone, squalene, and pentadecanoic acid, identified in multiple extracts, are associated with antioxidant and anti-inflammatory properties, supporting the traditional uses of H. tentaculatus for healing and stamina-boosting. Moslosooflavone, a principal component discovered, has substantial antioxidant and anti-inflammatory characteristics, essential for facilitating wound healing by alleviating oxidative stress and diminishing inflammation. These pathways are probable factors in the plant’s qualities that expedite healing, as historically used.17 Moreover, its function in mitigating cellular oxidative damage may contribute to increased stamina by improving overall cellular health and energy metabolism.18
Squalene, a significant component in H. tentaculatus, is acknowledged for its tissue healing properties attributed to its anti-inflammatory and antioxidant actions. This corresponds with the conventional use of the herb for promoting healing. Furthermore, squalene’s involvement in lipid metabolism may enhance stamina by aiding in energy balance and bolstering the immune system during recuperation.19 D-Allose, while less recognised, has shown antioxidant properties, rendering it advantageous for cellular protection throughout the healing process. Its capacity to influence immunological responses further substantiates its role in the healing acceleration typically ascribed to H. tentaculatus. These effects may contribute to increased stamina by bolstering overall immunological resilience after physical exertion.20 Pentadecanoic acid, found in many extracts, has antibacterial and anti-inflammatory properties that may assist in infection prevention during healing and facilitate tissue repair. Its function in mitigating inflammation corresponds with the historical use of H. tentaculatus for wound repair.21 The statistical analysis confirms the significant variance in the phytochemical compositions between different extracts, highlighting the critical role of solvent choice in maximizing the yield of specific bioactive compounds. The presence of compounds like D-Allose, Pentadecanoic acid, and Squalene, as detailed in Table 9, and their known biological activities underscore the pharmacological relevance of this plant. These compounds have been documented to exhibit antioxidant, antibacterial, and anti-inflammatory properties, which could potentially be harnessed for pharmaceutical development.

Moreover, the findings from the GC-MS study and the consistent identification of bioactive compounds in both macerated and sonicated extracts emphasize the reproducibility and efficiency of the extraction methods employed. This robustness in the phytochemical extraction process ensures that the plant’s potential for medicinal use is maximized, paving the way for further in-vivo studies and clinical trials.
Conclusion
This study highlights the significant phytochemical potential of Haplanthodes tentaculatus, as evidenced by GC-MS analysis identifying key compounds like Moslosooflavone and Squalene. These findings validate the traditional uses of the plant and underscore its potential for developing novel therapeutic agents. Future research should focus on in-vivo studies to explore the clinical efficacy of these compounds, aiming to integrate this plant into evidence-based medicinal practices.
