Since, human existence on earth, plants are being used for the treatment of various diseases. The specific uses of plants are mentioned in the traditional system of medicines like Ayurveda, Siddha, Unani, etc. Now a day’s plants are getting more important as medicines because plants are having fewer side effects, cost-effective, long effective life span and safe, etc. The present review covers the brief history of antimicrobials and list of plants as antimicrobials, approved, and banned antimicrobial drugs. In the present scenario, the use of herbal drugs is increasing progressively worldwide. Hence, this review shows useful data for researchers to develop new anti-microbials from plant...

The quality control assessment of herbal formulations is of great significance to justify their acceptability in the modern system of medicine though the drug may be therapeutically potent. Ayurvedic formulations prepared by several manufacturers are guaranteed to carry out the quality control test as per the standards mentioned in the Ayurvedic Formulary of India. Though the standards have been followed, still the variability in their results has been observed when compared between the same formulations. Vyoshadivati is one such polyherbal formulation consisted of 13 drugs and treated for ailments viz. Pinasa (coryza), Pratishaya (Rhinitis), Swarabheda (Hoarseness of voice), etc. An attempt is made here to compare Vyoshadivati prepared by GMP certified pharmacies with In house preparation. Results revealed that all the samples differ in their organoleptic, pH, and physicochemical properties. Thin Layer Chromato-graphic study showed sample B, D and E have an almost similar number of bands at the wavelength of 255 nm and 365 nm. Major difference was seen in disintegration time and hardness of sample A, i.e....

Nanosuspensions have the versatile potential for efficient exploitation of different drug delivery formulations and routes because of the properties provided by their small size. In the present study, curcumin extraction was carried out from Curcuma longa (crude curcuminoids) using soxhlet extraction method with ethanol as a solvent which gives a high yield. Formulations of nanosuspensions with the nanoprecipitation technique are made using polycaprolactone (PCL) as a polymer, with extracted natural curcumin, and with synthetic curcumin. A comparison is made for parameters such as product yield, drug content, drug entrapment efficiency and in-vitro studies between the formulation of nanosuspensions with naturally extracted curcumin and synthetic curcumin. Average particle size obtained ranging from 297.4 nm to 973.1 nm for different formulations with natural curcumin and 253.8 nm to 850.1 nm for different formulations with synthetic curcumin. Entrapment efficiency of nanosuspension ranged between 66.7% to 80.78% for natural curcumin and 68.78% to 80.86% for synthetic curcumin. Drug content ranged from 67.41% to 85.70% for formulation with natural drug and 68.27% to 83.27%...

Qualitative phytochemical screening of C. sativa leaf, stem and root was studied. Four solvents viz; n-hexane, chloroform, alcohol and aqueous revealed the variation in phytochemicals presence and absence in all studied parts. Extracts of different solvents were subjected to qualitative phytochemical screening using a standard protocol. Results showed the maximum number of phytochemicals present in leaf followed by stem and root. They are as follows; steroids, fixed oil, resins, alkaloids, terpenoids, flavonoids, tannin, proteins, and amino acid, phenolics, glycosides, saponins. Variation in a number of phytochemicals also observed in different solvents...
