\begin{abstract}
In the ethanolic extract of Tinosporacardifolialeaves, the current study amply confirmed the existence of tinosporine, beriberine, glycosidase A to E, alkaloids, and triterpenoids. Among the active components identified by the phytochemical screening procedures were alkaloids, triterpenoids, steroids, glycosides, tannins, polysaccharides, and phenols. These phytochemical elements would be responsible for the diverse pharmacological effects of Tinosporacardifolia. The evaluation of flavonoid content and in vitro methods of anti-diabetic activity of \ensuremath{\alpha }-Glucosidase inhibition method also show the efficacy of the ethanolic extract of Tinosporacardifoloia leaves in treating diabetes. The anti-oxidant action is carried out via the hydrogen peroxide scavenging method, which produces a 69\% inhibition. By using the protein denaturing process, the Tinosporacardifolia leaf extract shows a 43\% decrease of the anti-inflammatory effect. The retina was separated from the eyeballs as a result of the anti-diabetic retinopathy effect of goat eyeballs. The retinas are separated into reference and test samples for the ethanol extract. The Tinosporacardifolialeaves extract do not compare well to the benchmark. The pharmacological uses of Tinosporacardifolia are numerous. These include treatments for histamine, diabetes, high blood pressure, stress, arthritis, Parkinson's illness, HIV, and cancer.

\section{Introduction}
A hyperglycemia issue that affects that whole sight is named retinopathy. A vascular system of a light-sensitive epithelium within back of a retinal are now being effected (retina). Orginally, retinopathy may well not express such illnesses and may solely lead to slight perspective difficulties. A microvascular condition called diabetic retinopathy is a long-term effect of diabetes mellitus that causes vision loss and blindness. Even though persistent hyperglycemia causes increasing malfunction of the retinal blood vessel, it is first asymptomatic if untreated. Blindness and poor vision are the results. In the Western world, diabetes retinopathy is a common cause of significant vision loss in persons of working age groups. Around the world, 30\% of people have diabetic retinopathy. Clinically speaking, it is the retina's vascular anomalies manifesting themselves [Figure~\ref{f-d1319330ad91}] \unskip~\cite{1946827:28121741}.

There are two distinct forms of diabetic retinopathy. Proliferative diabetic retinopathy and non-proliferative diabetic retinopathy are the two types. In 2050, there will be around 16.0 million DR patients in America, with 3.4 million of them expected to have difficulties related to vision treatment. The early stages of DR, known as NPDR (non-proliferative diabetic retinopathy), are characterised by increased vascular permeability and capillary blockage in the retina. Fundus photography can identify retinal disorders including microaneurysm and retinal haemorrhage at this stage, even if the patients may be asymptomatic \unskip~\cite{1946827:28121749}. PDR (proliferative diabetic retinopathy) is defined by the development of new blood vessels on the surface of the retina or the optic disc and develops as a result of further retinal ischemia. These aberrant blood vessels have a tendency to bleed, which can cause vitreous haemorrhage, follow-up fibrosis, and fractional retinal detachment. Neovascularization is a feature of PDR, a more advanced stage of DR. When the new aberrant arteries bleed into the vitreous at this point, the patient may have severe vision impairment. When a patient has diabetic macular edema, the most typical reason for visual loss \unskip~\cite{1946827:28121734}.

Uncontrolled diabetes can cause a variety of visual problems, including diabetic retinopathy, the most common and serious ocular complication, cataracts, glaucoma, ocular surface abnormalities, recurrent style, and non-arteritic anterior ischemic optic neuropathy. The progression of diabetic retinopathy is linked to poor glycemic control, uncontrolled hypertension, dyslipidemia, nephropathy, male sex, and obesity. Recent research shows that the retinal neovascular unit and its interconnected vascular, neuronal, glial, and immunological cell are significantly impacted by diabetes \unskip~\cite{1946827:28121746}. Aloe, Tulasi, Neem, Turmeric, and Ginger are medicinal plants that treat a variety of common illnesses. These are commonly utilised as home remedies for illnesses across the nation. In a conventional system, tinosporacardifolia is an effective medicinal agent. Amrithavalli, Guduchi, Madhuparni, Giloya, Tippateega, Heart leaf, Moonseed, Gulancha, and other common names are among them. Anti-diabetic, antioxidant, antiviral, anti-microbial, anti-spasmodic, anti-cancer, and Parkinsonism treatments are all made with tinosporacardifolia. Additionally, it is used to treat fever, jaundice, chronic illnesses, dangerous organisms, diarrhoea, diabetes, skin conditions, poisonous bug bites, and eye problems. The research has primarily concentrated on naturally occurring anti-diabetic retinopathy, and many crude extracts and entirely natural substances have been shown to have positive effects on endothelial vascular growth factors as such. The primary goal of this study was to use accepted techniques to ascertain the plant leaf extract of Tinosporacordifolia's anti-diabetic retinopathy effectiveness.
    
\section{MATERIALS AND METHODS }
\textbf{Collection and Authentication}

The leaves of the Tinospora cordifolia plant was procured from Tirupati, Andhra Pradesh, India, which is close by. Dr K. Madhava Chetty, Assistant Professor, Department of Botany, Sri Venkateswara University, Tirupati, identified and verified the plant materials.

  Aqueous humor is ready about as room temp but also ph is 7.8 such as 72 hours. An amoxicillin 32mg\% but also streptomycin- 250mg\% have been got to add towards the pure culture to avoid microbial contamination. \ensuremath{\alpha }- Glucose oxidase but also glycemic in such a concentration like 55mm has been used to stimulate cataract. Experiment on goat retina: The fresh goat eyeballs were collected and separated retina from the goat eyeball. It is placed in already prepared (10\% of 1 ml \ensuremath{\alpha }-Glucosidase and with 2 gm of glucose) aqueous humor for 24 hours for induced diabetes. After 24 hrs the retina has small damage with brown color strikes and dots, swelling of the tissue and white milky appearance. These symptoms indicate induced diabetes. The retinas were separated for the treatment of ethanol extract of Tinospora cordifolia leaves by using the standard as Metformin. Two retinas are placed separately in test sample and standard sample. A test sample is ethanolic extract of Tinospora cordifolia leaves (10 mg/ml is taken for treatment. And the standard sample metformin (1 mg/ml) is taken with aqueous humor. After 24 hours absorbing the small changes in the retina, the white color retina changed normal white color and some strikers lightly disappear. The standard and Tinospora cordifolia leaves extract shows action on the retina.

\section{RESULTS AND DISCUSSION}
Tinospora cordifolia leaves hydroalcoholic extract has undergone preliminary phytochemical investigation. Alkaloids, triterpenoids, steroids, as well as sugars, glycosides, and phenols, are the main chemicals found in the ethanol extract [Tables~\ref{tw-96866ab86135} and~\ref{tw-ddc346c7692a}]. 

\textbf{Observation}

In the ethanol extract Alkaloids, triterpenoids, steroids are major compounds, carbohydrates, glycosides, and phenols are present.

Using a hydrogen peroxide radical scavenging assay, Tinospora cordifolia ethanolic extract was found to have anti-oxidant properties. the UV absorption was measured below 230 nm. The test sample's absorbance is inferior to that of the standard sample. Increased concentrations result in higher inhibition percentages, lower absorbance, and higher inhibition percentages. Using a hydrogen peroxide radical scavenging assay, Tinospora cordifolia ethanolic extract was found to have anti-oxidant properties. the UV absorption was measured below 230 nm. The test sample's absorbance is inferior to that of the standard sample. Increased concentrations result in higher inhibition percentages, lower absorbance, and higher inhibition percentages. The standard acarbose, ethanolic extract absorbance at 430 nm, and the anti-diabetic activity by alpha-Glucosidase inhibition technique for induced diabetes. As the concentrations rise, the absorbance falls while the concentration rises conversely, the percentage of inhibition rises. The concentration, absorbance, and percentage of inhibition of the anti-inflammatory action by Protein denaturing assay for Tinospora cordifolia ethanol extract and the standard Aspirin are considerably increased.

\textbf{Anti-oxidant activity}

The anti-oxidant activity by Hydrogen peroxide radical scavenging assay of ethanolic extract of Tinospora cordifolia leaves. The absorbance was measured under the 230 nm in UV. The standard sample absorbance is better than the test sample. When the concentration is increased the \% of inhibition is increased, absorbance is decreased, \% of inhibition is increased [Table~\ref{tw-9d6a1f358722}].

\textbf{Flavonoid content}

The total flavonoid content in sample of Tiinosporacardifolia leaves extract. The studies conducted by rutin as standard. The concentration of total flavonoid content is expressed by mg/gm of rutin equivalent. Maximum absorbance depends on the concentration of flavonoids [Table~\ref{tw-446016a8d2ad}]. 

\textbf{Anti-diabetic activity}

The anti-diabetic activity by \ensuremath{\alpha }-Glucosidase inhibition method for induced the diabetes, the absorbance is measured at 430nm for ethanolic extract, and the standard acarbose. As the concentrations increased the absorbances are decreased, the concentration is increased alternatively \% of inhibition increased [Table~\ref{tw-3b7dc3cbcd86}]. 

\textbf{Anti-inflammatory activity}

The anti-inflammatory activity by Protein denaturation assay for Tinospora cordifolia ethanol extract concentration and the standard Aspirin absorbance and \% of inhibition are relatively increased [Table~\ref{tw-de8e6a08175d}]. 
    
\section{CONCLUSION}
The current investigation amply demonstrated the presence of tinosporine, beriberine, glycosidase A to E, alkaloids, and triterpenoids in the ethanolic extract of Tinosporacardifolia leaves. Alkaloids, triterpenoids, steroids, glycosides, tannins, polysaccharides, and phenols were among the active ingredients that were found in the phytochemical screening processes' results. The various pharmacological effects of Tinosporacardifolia would be caused by the presence of these phytochemical components. The effectiveness of the Tinosporacardifoloia leaves ethanol extract in treating diabetes is demonstrated by measurement of flavonoid content and in vitro methods of anti-diabetic activity of alpha-Glucosidase inhibition method. The Hydrogen Peroxide Scavenging method is used to perform the anti-oxidant action, and it results in a 69\% inhibition. The Tinosporacardifolia leaf extract exhibits a 43\% suppression of the anti-inflammatory action as measured by protein denaturing technique. Goat eyeballs performed anti-diabetic retinopathy action, and the retina was detached from the eyeballs. For the reference and test samples of the ethanol extract, the retinas are divided. The extract from Tinosporacardifolia leaves do not compare favourably to the standard. There are various pharmacological functions for Tinosporacardifolia. These include medications for diabetes, hypertension, stress, arthritis, Parkinson's disease, HIV, cancer, and histamine.
