ABSTRACT: Purpose: Sanshamani Vati (SHV) is useful in all types of Jwara, and Mahalaxmivilas Rasa (MLVR) is the best drug in various cardiovascular and respiratory disorders. To maintain the enormous trust in Ayurveda, it’s necessary to ascertain the quality, efficacy & safety of Ayurvedic formulations on scientific lines using modern techniques. Present work attempts have been made to standardize the traditional Ayurvedic formulations - SHV and MLVR with modern techniques. Method: The formulations were standardized for physicochemical, Elemental and phytochemical screening. The XRD profiling was done for MLVR. Also the authentication of RM used in SHV was done using HPTLC. The validation of the methods for Elemental and phytochemical assays was performed as per ICH guidelines. Results: The Physico-chemical and phyto-chemical screening of Sanshamani Vati, and Mahalaxmivilas Rasa Tablets was done. The HPTLC profile confirms the presence of Berberine at Rf 0.25 ± 0.02 in SHV and Myristicin at Rf 0.50 ± 0.02 in MLVR. The elemental content of Gold (Au), Iron (Fe), Mercury (Hg) & Copper (Cu) in MLVR was estimated by ICP-OES. HPTLC Densitogram confirms the presence of authenticated Tinospora cordifolia RM in SHV. The XRD profile confirms the absence of free toxic metals – Hg & As. Conclusion: The present work will help understand therapeutic value concerning the quality parameters of the formulations. The standardization parameters presented in this research may serve as a standard reference to set the quality parameters for Sanshamani Vati and Mahalaxmivilas Rasa.

INTRODUCTION: Ayurveda is the world's oldest medical system believed to deal wide range of infections without causing any side effects 1. This traditional Indian medicine network is entrusted since human existence and plays a vital role in combating and catering to global healthcare needs 2.
Recent studies affirmed that about 70-80% of people, including developing countries, now rely on herbal medicines for their primary healthcare compared to modern allopathic drugs 3.
In India, the Ministry of Ayush (Ayurveda, Yoga, Unani, Siddha & Homeopathy) and an advisory coronavirus committee has also published some guidelines and recommendations with preventive management steps as per Ayurvedic practices through boosting immunity and several Ayurvedic medicines for symptomatic management of Coronavirus infection during the pandemic 4, 5. In Ayurveda, it is mentioned that the Rasayana Chikitsa or therapy promotes and rejuvenates physical as well as mental health of the body and produces resistance against diseases. As per modern science, the Rasayana therapy enhances immune responsiveness of an organism against pathogens by activating the immune system with immunomodulatory agents of plant origin 6. In Ayurvedic Rasayana, many medicinal plants are valued for their therapeutic potential with immunomodulatory, anti-inflammatory, antioxidant, antidepressant activities and have been scientifically proven with promising effect based on the recommendation by Ministry of AYUSH, Govt of India 7, 8.
In Ayurveda, "Rasayana botanicals” such as Shatavari (Asparagus racemosus), Guduchi (Tinospora cordifolia) and Ashwagandha (Withania somnifera) known to modulate the immune system and possess antiviral activities are used for rejuvenation by boosting the immune system and alleviating disease condition 9-14. With reference to Bhavprakash Nighantu (an Ayurvedic text), Guduchi (Tinospora cordifolia) is categorized as “Rasayana” 15 and used for its anti-inflammatory 16, 17, 24, immunomodulatory 17-20, anti-allergic 20, antipyretic 20, antidiabetic 17, 20, 21 properties. Sanshamani vati i.e. Guduchi Ghan (concentrated form of decoction) Vati an Ayurvedic preparation, is used as adjuvant in various hospital trials against COVID-19 due to its anti-inflammatory, antimicrobial and immuno-modulation properties 22-25.
In-silico studies also confirmed that the phytochemical compounds of Guduchi (Tinospora cordifolia), Berberine and Sitosterol found as most powerful inhibitors against COVID-19 26, 27. Tinospora cordifolia is the accepted botanical source for Guduchi in Indian Ayurveda system. Despite of this fact, Tinospora crispa is used as substitute and sometimes as adulterant to Tinospora cordifolia in the formulations due to their similarities 27. Many cases reveal that Tinospora crispa might have the negative effect of inducing hepatotoxicity 29. To avoid such circumstances, a system must be developed to confirm Tinospora cordifolia species in the formulation instead of Tinospora crispa. In addition to Rasayan botanicals, the Ayurvedic rasa-aushadhis are also having qualities such as instant effectiveness, requirement in very small dosage and abundant therapeutic utility 30. These Rasa-aushadhis have been used to treat chronic ailments since time immemorial 29. Mahalaxmivilas Rasa, a herbo-mineral-metallic preparation, comes under the Khalviya Rasayana (A preparation method of Rasa-aushadhis) 30. It has broader therapeutic activity in Urdhwa Jatrugata rogas (Upper Respiratory Disorders), kasa (Cough), Pinasa (Chronicrhinitis/sinusitis), Gala Roga (Diseases of throat), Atisara (Diarrhoea), Nasa Roga (Disease of nose), Netraroga (Eye disorder), Mukha Roga (Disease of mouth) 30, 31. The Rasa-aushadhis are the Formulations made by mercury and incinerated metals and minerals 30. Mercury is an extremely hazardous heavy metal known for its toxicity to human health 32. It undergoes extensive detoxification procedures before being used in any formulation. The toxicity of Mercury is seen mainly due to its elemental and organic form and not due to inorganic form. Inorganic mercury is considered to be the least toxic among the different forms of mercury 33-34.
Considering the therapeutic effect of Sanshamani Vati and Mahalaxmi vilas rasa, the attempt of present work has been made to characterize and validate the formulations with modern techniques and to prove their safety of the formulations. The present work will help understand therapeutic value concerning the quality parameters of the formulations.

Validation of the Method: The Method validation was performed for Phytochemical Quantification by HPTLC and Elemental Analysis by ICP-OES as per standard ICH guidelines, which included linearity, precision, accuracy, LOD and LOQ 35. The linearity of method was performed by plotting calibration curves. Precision was performed by Repeatability and by estimating intraday and interday readings and %RSD relative standard deviation. Accuracy of analytical methods was expressed as % recovery. This was estimated by adding known concentration of standard solution to pre-analyzed sample solution. Limit of detection (LOD) and limit of quantification (LOQ) were estimated as per formula:
LOD = 3.3 x σ/S and LOQ = 10 x σ/S,
Where σ = Standard deviation, S = Slope.
X-ray Diffraction (XRD) Profile: X-ray diffraction (XRD) analysis of Mahalaxmi vilas Rasa was carried out using Rigaku Miniflex 600 X-ray diffract meter with operating at 40 kV and 30 mA. The XRD Pattern was recorded for angle ranging from 30 to 1000 at a scanning rate of 30/ min. and scan step of 0.010. The absence of Mercury & Arsenic in free from was confirmed by matching d-spacing with the standard database ICDD PDF-2 2021 (International Center for Diffraction Data).
RESULTS AND DISCUSSION: Sanshamani Vati, and Mahalaxmi vilas Rasa Tablets were characterized as brownish black to black and Greenish gray to dark gray in colour, respectively with round coated biconvex shape. The Physico-chemical screening of both Sanshamani Vati, and Mahalaxmi vilas Rasa Tablets showed Friability less than 1%, Hardness greater than 1.5 kg/cm2, Disintegration time less than 60 min and Loss on drying (LOD) less than 6 %. Sanshamani Vati Tablets showed Ash content less than 30 %, Acid insoluble ash (AIA) less than 2 %, Water soluble Extractive (WSE) more than 45 % and Alcohol soluble Extractive (ASE) more than 20 % Table 5. All the samples of Sanshamani Vati, and Mahalaxmi vilas Rasa were found to comply with the weight variation test as per API 36. Weight variation is an important factor that is affected by the tooling of the compression machine, head pressure, machine speed and flow properties of the powder, powder or granulate density and particle size. The friability test helps to determine the tablet’s physical strength, which is attributed to the tablet breaking force. The disintegration test is a measure of the time required under specified conditions for the tablets to disintegrate into particles. Loss on drying (LOD) measures the amount of water and volatile matter in a sample when the sample is dried under specified conditions. This is the major factor responsible for the deterioration of the drugs and formulations. Low moisture content is always useful for higher stability of drugs 37-38.

Method Validation by HPTLC: For development of a successful method the first important step is to optimize the mobile phase. Trials with various solvent system combinations carried out mobile phase optimization. The chamber saturation time was optimized to 20 min at room temperature with relative humidity 38 ± 2%. The chromatographic run was roughly 90 mm, and the distance between two tracks was 15 mm. The optimized chromatographic conditions are given in Table 2.
Specificity: It was observed that other phytochemical constituents present in Sanshamani vati & Mahalaxmivilas rasa did not interfere with the peaks of Berberine and Myristicin, respectively.
Thus the proposed method was proved to be specific. The spectra of standard Berberine and Myristicin corresponded with Sanshamani vati & Mahalaxmi vilas rasa are shown in Fig. 4 & 5.
