Considering the importance of natural products in cancer therapy, a preliminary investigation on some anticancer medicinal plants of north-eastern states of India was conducted in murine tumor model. Nine different plants such as Ageratum conizoides Linn. (Asteraceae), Blumea lanceolaria Linn. (Asteraceae), Dillenia pentagyna Roxb. (Dilleniaceae), Potentilla fulgens Wall. (Rosaceae), Taxus bacc...

The purpose of this paper is to present a review of highly developed medicinal usages of plants in the treatment of cancer. In the last decades, the cancer treatment has been included in this range of plant use, due to plant active substances. Active substances or secondary metabolites are generally known for their widespread application. When it comes to the cancer treatment, these substances ...

Evolution of the phenolic metabolism was critical for the transition of plants from water to land. A cytochrome P450, CYP73, with cinnamate 4-hydroxylase (C4H) activity, catalyzes the first plant-specific and rate-limiting step in this pathway. The CYP73 gene is absent from green algae, and first detected in bryophytes. A CYP73 duplication occurred in the ancestor of seed plants and was retaine...

To study the evolutionary relationships among the four living gymnosperm orders and the interfamilial relationships in each order, a set of 65 nuclear 18S rRNA sequences from ferns, gymnosperms, and angiosperms was analyzed using the neighbor-joining and maximum-parsimony methods. With Selaginella as the outgroup, the analysis strongly indicates that the seed plants form a monophyletic group wi...

The Early Cretaceous Huolinhe Formation in eastern Inner Mongolia, northeastern China has yielded abundant and diverse plant fossils, to which we here add a new species of Taxus based on exceptionally well-preserved, lignified leaves from the Gucheng open-cast coal mine. huolingolensis sp. nov. linear with lamina that tapers an acute mucronate apex, narrows into decurrent, stalk-like base. midr...

Podocarpus is the most dominant genus of Podocarpaceae, with higher taxonomical proximity to Taxaceae, having numerous pharmaceutical applications, however, scarce studies dealing physiological and metabolic criteria in Egypt were reported. Thus, objective this work was assess metabolical patterns different species Podocarpus; P. gracilior, elongates, macrophyllus neriifolius. The highest terpe...
