Historical uses of Catharanthus roseus in the treatment of diabetes, fever, malaria, regulation of menstrual cycle, throat infection and chest complaints have been reported. Only few plants have the anticancer properties and periwinkle is one of them. The physiologically important and antineoplastic alkaloids, vinblastine and vincristine, are mainly present in leaves and antihypertensive alkaloids are found in roots such as ajmalicine, serpentine and reserpine. Vincristine and vinblastine have extensive use in modern medicine as potential anticancer compounds. Above medicinal properties are worth attracting the attention of plant scientists to increase the secondary metabolites of this plant. The growth and active constituents production of medicinal plants can be altered by the application of several PGRs.The present study explore the role of two well known PGRs namely gibberellic acid and triacontanol to increase the productivity aanticancerous alkaloids in Catharanthus roseus L.

Herbal medicines are in great demand in both developed and the developing countries because even in many of the modern medicines, the basic composition of drugs is derived from plants due to their easy availability, least side effects, low prices, and long-lasting curative properties. Turmeric (Curcuma longa L.) occupy prominent positions both in ancient and modern systems of medicine. Though India is a major producer of turmeric, the growing on supply demand owing to its nutritive and therapeutic values is putting a heavy strain in the market. To overcome this critical situation, its enhanced production with value addition, if possible, is extra-ordinarily desirable. Thus, it is necessary to improve the techniques of cultivation and increase the per hectare yield of the medicinal and spice crops through balanced nutrition. This work provides valuable information regarding mineral nutrition strategies for the cultivation of this important spice crop. The application of mineral nutrients through roots improves the productivity and quality attributes and production of curcumin content in Curcuma longa L.

Malaria is thought to be among the oldest of human diseases. It has long had serious effects on morbidity and mortality, and in turn on the economic and social fabric of nations and society. Various methods have long been utilized to mitigate its frequency and effects in both temperate and tropical climates. Presently the most effective treatment of malaria is based on derivatives of artemisinin, an extract from the plant Artemisia annua. Only artemisinin-based combination therapies (ACTs) meets international standards set-up by WHO and UNICEF for the cure of malaria. The present demand for artemisinin is far more than that of supply, therefore, researchers are working round the world towards improving artemisinin content in the plant by various means. This work explains the potential use of radiolytically derived oligomers of sodium alginate together with soil-applied phosphorus induce the productivity and artemisinin (antimalarial drug) synthesis in Artemisia annua plants.
