The medicinal plant Gymnema sylvestre found in the Indian subcontinent and Srilanka is known for its anti-diabetic, diuretic, anti-obesity, anti-cancer, antimicrobial, anti-inflammatory properties. The current study is focused on the phyto compound extraction efficiency of different solvents like ethanol, methanol, ethyl acetate, hexane, benzene and chloroform by gas chromatography{\textendash}mass spectrometry analysis of Gymenma sylvestre. From the results, it is concluded that G. sylvestre leaves extracts contains more than 38 phyto compounds with natural antioxidants potential. Further analysis of the extract will help in identifying the effective compounds which can be of potent use in the pharmacological field.

Background: Cardiospermum halicacabum (C. halicacabum) is a common medicinal herb found in India and other Asian countries. It has various medicinal properties such as antimicrobial, pain relief, antibiotics, anti-inflammatory, antioxidants, anticancer etc. It is commonly used for treating diabetes, arthritis, limbs stiffness, rheumatism, lumbago, earache, fever. Type of solvent and polarity intensively affects the antioxidant activity of the extracts due to the solubility of the phytocompounds such as polyphenols and flavonoids in various solvents. Materials and Methods: In this study, different solvents like, ethanol, methanol, chloroform and petroleum ether were used for the extraction of C. halicacabum. Cold maceration method was followed for extraction. The crude extracts were screened preliminary and then confirmed using Fourier transform-infrared spectroscopy analysis. Gas chromatography-mass spectrometry was used to determine the chemical composition of each extract. The DPPH (2,2-diphenyl- 1-picrylhydrazyl) method was used for the evaluation of the antioxidant activity of different crude extracts of C. halicacabum. Results: The results showed that there is significant influence of solvent type in preserving various phytocompounds of the C. halicacabum leaves extract. The evaluation of the antioxidant capacity of different crude extracts was in the order of ethanol \> methanol \> petroleum ether \> chloroform extract.

Background: Plants serve as an important source for curing various medical ailments for a wide variety of human and animal diseases. It is therefore necessary to prove the biological activities of the selected plants scientifically using modern technology. The current study focuses on the use of Cardiospermum halicacabum in their wound healing applications. Cardiospermum halicacabum is a well-known plant that has antibacterial, anti-inflammatory, anti-rheumatic properties and it is also used to treat joint pains, muscle tears, back pain, etc. Materials and Methods: In this study methanolic extracts of the active compounds from Cardiospermum halicacabum were tested for its phytochemical attributes by qualitative method, GC-MS, and the antioxidant properties were also assessed. The bactericidal activity and Minimal Inhibitory concentration (MIC) of the plant extract has been evaluated in both Gram +ve and Gram -ve microorganisms using the disc diffusion method. Results: The results obtained showed the presence of significant antibacterial and antioxidant activity. The plant extract was found to be more active against Gram positive microbes compared to Gram negative microbes. The extract has the radical scavenging activity of about 77\%. And the GCMS results showed the presence of different phytocompounds which are greatly known for their pharmacognistic activities.
