A rapid, simple and specific reversed phase High Performance Liquid Chromatographic (RP-HPLC) method has been developed for the quantitative determination of alizarin in the methanolic extracts of roots and aerial parts of Rubia cordifolia Linn, an important medicinal plant used in Ayurveda system of medicine. Chromatographic analysis was performed by using a C18 column (250 × 4.6 mm) alizarin ...

introduction: skeletal staining is an important part of anatomical studies which can evaluate macroscopic disorders in bones and cartilages development. the aim of the present article is to illustrate two distinct protocols by all details in order to stain skeletal system of the lab animals in all ages of their lives so it becomes easy for future studies in this field. methods: in this paper, s...

The relationships between otolith score, a function of increasing stain visibility, and the ratio of alizarin complexone (mg) to fish biomass (g) for 0.1, 0.6 and 7 g black bream Acanthopagrus butcheri show that acceptable marks are produced in all size classes using a stain-to-biomass ratio of 3.3 mg g(-1) following an immersion period of 24 h.

A skeletal examination of fetuses is required in regulatory embryo-fetal development studies. This chapter describes a method of skeletal examination using alizarin staining. All fetuses are removed from the mother by caesarean section before birth. The fetuses are first examined externally. For larger species (rabbit and minipig), an internal examination can be performed on the fresh soft tiss...

Background & Aim: Rubiatinctorum is one of the most well-known medicinal plants whose alizarin and other anthraquinones which are outstanding color agents with some trace of pharmaceutical properties are isolated from it. The objective of this study was to optimize alizarin production in intact plant of R.tinctorum by induction with biotic elicitors. ...
