#andrographis paniculata

Andrographis paniculata, Allium sativum and Adhatoda vasica are the three important medicinal plants in which it is used for daily consumption by the user especially in the rural areas. Not only rural people are seeking for the medical benefits from the medicinal plants but also urban people because trying to eliminate the side effects of synthetic medicine on health. Research using these three plants should not stop here and must be extensively employed by the researchers and try to get more medical properties which is useful for the public. Andrographolide from Andrographis paniculata is the active component obtained from the aerial parts of this plant, having very bitter taste. It is a bicyclic diterpenoid lactone with multiple pharmacological activities. In 1997, garlic (Allium sativum) was the most widely used natural supplement in US house-holds. Garlic was shown to be used more than twice as much as any other natural supplement. Extract of Adhatoda vasica leaves has been used for the treatment of various diseases and disorders in Ayurved and Unani medicine. The plant has been used in the indigenous system of medicine in India for more than 2000 years. Compounds which are present in the plant/s which when consumed it promote the health of the consumers although some studies suggest that consumption may lead to toxic effect but in general it is safe to consume moderately. In many literature survey, researchers are trying the best to overcome the bacterial resistance by isolating compounds from the medicinal plants (one of the method) due to the resistance of bacterias towards synthetic chemicals. Overally this proved the importance of the medicinal plants.

A lot of literature reviews about Andrographis paniculata has been published previously. Researchers are critically involved in the research to extract out the potential medicinal value that possess by the “King of Bitter”. It has a broad pharmacological value. Traditionally many disease condition have been treated successfully. The success of the plant is due to the presence of few bioactive compounds such as andrographolide, homo-andrographolide andrographesterol, andrographopne which are identified through the phythochemistry studies of the plant which are having the wide therapeutic activities. The extremely bitter taste of the plant is due the compound known as andrographolide. However this bitter plant is having a sweet future for those appreciated the benefits of the plant. From the review it is proven that Andrographis paniculata is having antioxidant, hepatoprotective, antimicrobial, anticancer, antivenom, anti HIV, antimalarial, antipyretic, antifertility, antidiarrhoeal, antidiabetic, antihiperlipidemic activities. Variety of literature concerning about the toxicity studies has confirmed that the plant is safe to consume although few findings revealed that consuming Andrographis paniculata for a long period of time may possess some unwanted action especially in the fertility studies.

The present research explains a rapid and environmental friendly route for the synthesis of highly stabilized silver nanoparticles using the Andrographis paniculata leaf extract. The biosynthesized silver nanoparticles were characterized by using UV-visible spectrophotometer, Fourier Transform Infrared spectroscopy, X-ray diffraction, and Scanning electron microscope. The UV- visible spectrum exhibited surface Plasmon resonance band at 421 nm signifies the presence of silver nanoparticles in the reaction mixture. The XRD technique revealed the synthesized nanoparticles were crystalline in nature as well as possess face centered cubic geometry. FTIR studies were carried out to investigate the functional groups responsible for the silver nanoparticle reduction in the range 4000 – 400cm-1. EDAX analysis displayed the elemental composition in the sample. SEM analysis confirmed the synthesized particles are polydispersed in nature. The inhibition zone gradually increased with increase in silver nanoparticle concentration. Further the silver nanoparticle exhibited an effective germicidal activity against both Gram positive and Gram negative organisms by using disc diffusion method. The in-vitro antimicrobial assay demonstrated the results of maximum inhibition zone with the (36±0.334) in Lactobacillus sp and minimum zone with (15±0.318) in Streptococcus sp. Because of the potent antimicrobial activity it might be concluded that silver nanoparticles were efficiently utilized as an effective antibacterial compounds.
