Myricetin is a member of the group of flavonoids called flavonols. Myricetin is obtained from various fruit, vegetables, tea, berries and red wine. Myricetin is characterized by the pysrogallol B-ring, and the more hydroxylated structure is known to be capable for its increased biological properties compared with other flavonols. Myricetin is produced by the Myricaceae, Anacardiaceae, Polygonaceae, Pinaceae and Primulacea families. It is soluble in organic solvent such as ethanol, DMSO (dimethyl sulfoxide), and dimethyl formamide (DMF). It is sparingly soluble in aqueous buffers. Myricetin shows its various pharmacological activities including antioxidant, anti-amyloidogenic, antibacterial, antiviral, antidiabetic, anticancer, anti-inflammatory, anti-epileptic and anti-ulcer. This review article focuses on pharmacological effects of Myricetin on different diseases such as osteoporotic disorder, anti-inflammatory disorder, alzheimer’s disease, anti-epileptic, cancer, cardiac disorder, diabetic metabolic disorder, hepatoprotective disorder and gastro protective disorder.

Anacyclus pyrethrum an amazing medicinal plant is one of the most widely growing species of the family Asteraceae. The present review endow with significant information about its phytochemical investigations, pharmacological activities and medicinal properties as a folk medicine to treat several disease like anti-rheumatic, analgesic, antibacterial, antiviral, carminative, anti-catarrh, improve digestion, emmenagogue, febrifuge, nervine, vermifuge, and sialagogue. The plant has been reported several pharmacological actions such as antidiabetic, immunostimulating effect, inhibitory effects, antidepressant activity, anticonvulsant activity, memory-enhancing activity, aphrodisiacs, antimicrobial activity, antioxidant, local anesthetic effect, insecticidal effect, action on COX and LOX, interactions with testosterone, interaction with libido, and it interaction with testicles. Mainly the root portion has beneficial properties that can serve the mankind. The entire plant can be extensively studied for further future prospective.

Background: Silver nanoparticles play a significant role in bioavailability and refining the compatibility of natural drugs in the treatment of various chronic diseases including different types of cancer. Objective: Green synthesis of silver nanocomposites of Nigella sativa seeds extract to evaluate the anticancer effects against hepatocellular carcinoma using HepG2 cell lines. Methods: The AgNCs were developed by treating aqueous extract of N. sativa seeds treated with silver nitrate (1mM) solution and were used to test its efficacy against hepatocellular carcinoma using HepG2 cell lines. Results and Discussion: The Surface Plasmon Resonance (SPR) of prepared AgNCs showed a peak at 432 nm via UV spectroscopy. The selected N. sativa AgNCs were characterized for polydispersity, surface charge and size and the results showed 0.215±0.093 polydispersity index (PDI), zeta potential 18.8±0.372 mV and size range 10-20 nm, respectively. The Fourier transform infrared spectroscopy (FTIR) also showed various peak of functional groups that are possibly involved in the reduction of silver ion and synthesized the N. sativa silver nanocomposites, respectively. N. sativa AgNCs showed 89.954% drug release while in the case of extract release, it was only 33.821% in 24 hrs. Further, in vitro studies of N. sativa AgNCs against hepatocellular carcinoma showed good cytotoxic effect p<0.05 with 7.16 µg/ml IC50 value. Conclusion: Thus, the present results revealed that green synthesis of N. sativa AgNCs can be an alternative tool for clinical application in cancer therapy; however, there is a need to find the mechanism and role of AgNCs inside the individual.

Pterocarpus marsupium is an important therapeutic and medicinal plant belonging to family Fabaceae and commonly named as Indian Kino tree, Bijasal, Venga or Vijayasara. It is a huge deciduous plant and widely distributed in the Central, Western and Southern regions of India. Role of P. marsupium is found in Ayurveda, Homeopathic and Unani systems of medicine. It is a decent source of tannins and flavonoids hence, used as influential astringent, anodyne, cooling, regenerating agent and also used for the treatments of leprosy, leucoderma, toothache, fractures, diarrhea, passive hemorrhage, and dysentery, bruises and diabetes. It is also used to treat rheumatoid arthritis, gout, diabetic anemia, indigestion, asthma, cough, discoloration of hair, bronchitis, ophthalmic complications, elephantiasis and erysipelas. Researchers have been stated the presence of several phytoconstituents in P. marsupium and also their pharmacological activities. The current review aimed to define the phytochemical and pharmacological aspects of P. marsupium which will have been help in the researchers for further qualitative research.
