Pramod K. Raghav & Mitu Saini,IJGHC, December 2017 – February 2018; Sec. B; Vol.7, No.1, 020-032.DOI: 10.24214/IJGHC/HC/7/1/02032.

Plants are excellent source of active components which act as a natural antimicrobial agent and used for treatment of various diseases in whole world from ancient time. As a result the main focus of researchers is on the plants, especially herbs and spices. Tulsi is most sacred plant of the India. It is cultivated for medicinal and religious purposes. Ocimum sanctum has many beneficial properties namely anti-oxidative, antimicrobial, antistress, antidiabetic, antiviral and many others that’s why this plant is also given the term “Queen of Herbs”. Tulsi is one of the most important aromatic herb, which is widely used in Pharmaceutical Industry. O. sanctum is mostly used in the form of extract and oil. The main secondary metabolites of Tulsi extract is Eugenol, Linalool, β-Caryophyllene, Carvacrol, Apigenin, Rosmarinic Acid, Urosolic Acid, these are derivatives of alkaloids, phenols, glycosides, flavonoids, tannins, saponins, terpenoids, steroids and quinone isolated from Ocimum sanctum and other medicinal plants. Tulsi leaves extract also inhibit the growth of pathogens which is responsible for spoilage of fresh produce. Tulsi extract shows inhibitory effects against pathogens such as Staphylococcus aureus, Pseudomonas aeruginosa, E. coli, Klebsiella pneumonia, Proteus mirabilis, Salmonella typhimurium, Salmonella typhae, Shigella dysentriae, Bacillus pumilus, Aspergillus spp., Candida albican and Penicellium spp. Essential oil and extract of Tulsi leaves have antiviral properties that’s why it is used extensively in medical practices. It is an excellent antimicrobial agent so it is used in food products as an ingredient as well as medicine.">

Comparative Study of Phytochemical and Antioxidant Activities of Two Endangered Medicinal Plants of Western Himalayas 

Surbhi Soni, Rabia Sharma, P. K. Chauhan and Pankaj Sharma,IJGHC, December 2017 – February 2018; Sec. B; Vol.7, No.1, 012-019.DOI: 10.24214/IJGHC/HC/7/1/01219.

The aim of present work was to investigate and compare the phytochemical and antioxidant activities of two endangered medicinal plant species (Picrorhiza kurroa and Rauwolfia serpentina) of Western Himalayas. Leaf samples of both the plant species were collected from wild (W) and field grown (FG) habitats. Phytochemical analysis of both plant extracts taken from wild and field grown habitats showed the presence of different phytochemicals such as total phenols, terpenoids, flavanoids and reducing sugars, whereas alkaloids, steroids and saponins were found to be absent in all samples. Both total phenolic and total flavanoid contents were found to be high in wild variety of P. and low in field grown variety of R. serpentine. IC50 values of DPPH assay and Nitric oxide radical scavenging assay were found to be high in chloroform leaf extract of P. kurroa (W) i.e. 56.8μg/ml and 56.8μg/ml respectively. FRAP assay of all extracts followed concentration dependent activities with highest values of leaf extract of P. kurroa (W). Results revealed that the chloroform leaf extract of P. kurroa possess good antioxidant potential than R. serpentine; wild varieties of both species showed good phytochemical as well as antioxidant properties than field grown varieties.

Study of Antimicrobial Activity of Some Medicinal Plants againstEscherichia Coli, KlebsiellaSp., StaphylococcusSp. And Pseudomonas Species.

Madhulika Singh and PriyaRathore,IJGHC, December 2017 – February 2018; Sec. B; Vol.7, No.1, 001-011.DOI: 10.24214/IJGHC/HC/7/1/00111

In recent years, renewed interest has been shown in the use of medicinal plants and scientific studies are been designed to explain some of the curative phenomena associated with traditional herbal remedies. Most drugs utilized by people all over the world are of plant origin. The use of herbal remedies has increased significantly in the last one decade. This has led to the production of herbal products. The microbial of curing all manners of microbial diseases were assessed. The herbal remedies were discovered to eliminate the contamination done by the following microorganisms: Escherichia coli, Klebsiella sp., Staphylococcus sp. and Pseudomonas sp. The distilled water, ethanol, and aqueous extract of three medicinal plants were evaluated for activity against medically important bacteria such as Escherichia coli, Klebsiella sp., Staphylococcus sp. and Pseudomonas sp. The Invitro antimicrobial activity were performed by agar well diffusion method and disc diffusion method. The plates are incubated at 37°C in incubator. The zones of inhibition were observed after this and observe the susceptibility towards the herbal drugs. The ethanol extract of garlic inhibited the growth of both gram positive and gram negative test bacterial cultures. The maximum activity was noted against Staphylococcus, Escherichia coli and minimum antibacterial activity against Pseudomonas. A zone of 12 mm was recorded Escherichia coli, Staphylococcus by ethanol.

Vyas Seema, Mali M.C. , Verma S.K. and Bhojak N.,IJGHC, September 2017 – November 2017; Sec. B; Vol.6, No.4, 117-143.,DOI: 10.24214/IJGHC/HC/6/4/11743.

Rajasthan has geographic area of 342,239 square kilometers, has become geographically the largest state in India acquiring almost 11% of the total Geographical area of India, Located at 23º30´ and 30º 11’ North latitude and 69º 29’ and 78º 17’ East longitude is blessed with all three features i.e. mountains, plateaus and plains. The oldest range of mountains - Aravalli, biggest Indian desert the Thar or Maru-Kantar and the other arid regions, the Plateaus of Vindhaya and the Malwa, the Fertile plains in the Mewar, the Forest Regions and the Water resources including Rivers and Salt Lakes. In the present paper 389 Medicinal plants used in Indian system of medicine from Rajasthan state have been surveyed and catagorised systematically with their important traditional application for the cure of various ailments.

Phytochemical screening and antibacterial assay of the essential oil from Carpesium cernuum L.

Lalit S. Bisht, Rajendra Prasad, Deepshikha Joshi, Manoj K. Nailwal and Anand B. Melkani, IJGHC, September 2017 – November 2017; Sec. B; Vol.6, No.4, 107-116, DOI: 10.24214/IJGHC/HC/6/4/10716.

Carpesium Cernuum L. (Asteraceae) growing wild in Kumaon and Garhwal region of the central Himalaya, is an herb of several medicinal properties. The essential oil from whole aerial parts of plant was extracted by steam distillation and analyzed by GC-FID and GC-MS. Total forty-five constituents were identified which represented 81.4% of the total oil composition. The essential oil was found rich in oxygenated sesquiterpene (38.6%) with sesquicineole (13.8%), α-bisabolol (9.6%) and myrtenal (6.0%) as the principal constituents. In-vitro antibacterial screening of the oil against ten bacterial strains showed significant activity against Xanthomonas phaseoli, Staphylococcus aureus and Salmonella enterica enterica. The essential oil showed minimum inhibitory concentration at 31.25 μL/mL against Escherichia coli, Pasteurella multocida, Enterococcus faecalis, Agrobacterium tumifaciens, Xanthomonas phaseoli, Bacillus subtilis, Staphylococcus aureus and Salmonella enterica enterica.
