vasicine/justicia

A simple high-performance thin-layer chromatographic (HPTLC) method has been developed for the simultaneous determination of the pharmacologically important quinazoline alkaloids vasicine and vasicinone in Adhatoda vasica. The assay combines the separation and quantification of the analytes on

Vasicine (1) was isolated from the ethanolic extract of Adhatoda vasica Nees (Acanthaceae) and the structure was confirmed using spectroscopic techniques. Acetylcholine esterase, trypsin, DPPH inhibition potential and FRAP assay were carried out using in vitro models. The results showed 38.4 ± 1.2%

A new method of capillary electrophoresis was developed for the quantitative determination of vasicine and vasicinone from Adhatoda vasica (L.) Nees. The electrophoretic separation was performed using a 47 cm x 50 microm ID (38.5 cm effective length) fused silica capillary. The samples were injected

Adhatoda vasica (L.) (Acanthaceae) is used in the indigenous system of medicine in India. The alkaloid Vasicine was isolated from ethanolic extract of the leaves of A. vasica using column chromatography. Vasicine acetate was obtained by acetylation of Vasicine. Vasicine acetate exhibited good zone

BACKGROUND Adhatoda vasica a perennial herb has been used in Ayurvedic and Unani system of medicines since last 2000 years and has been employed for the treatment of respiratory tract ailments. OBJECTIVE To develop and validate new, rapid, and highly sensitive high throughput ultra-performance

Leaf of Adhatoda vasica (Vasaka) is an important drug of Ayurveda, prescribed as an expectorant. Quinazoline alkaloids present in the leaves are established as active principles. In Ayurveda, its leaf juice (Vasa swarasa) is incorporated in many formulations. Classical method for extracting the

Vasicine, an abundantly available quinazoline alkaloid from the leaves of Adhatoda vasica, has been successfully employed for metal- and base-free reduction of nitroarenes to the corresponding anilines in water. The method is chemoselective and tolerates a wide range of reducible functional groups,

Tuberculosis (TB) is known to mankind as one of the most pervasive and persistent of diseases since the early days of civilization. The growing resistance of the causative pathogen Mycobacterium tuberculosis to the standard drug regimen for TB poses further difficulty in its treatment and control.

The present study brings out the interaction between vasicine, an alkaloid of Adhatoda vasica Nees with double stranded DNA [corrected]. The physico-chemical interaction between small molecules and nucleic acids is a major area of focus in screening drugs against various cancers. Molecular probing

The distribution pattern of the alkaloids of A. Vasica has been studied with change of season. The study also resulted in the detection of glycosides and N-oxides of vasicine and vasicinone.

In folk medicine, Adhatoda vasica Ness. (Acanthaceae) is used to treat asthma and cough. The leaves of A. vasica were powdered and extracted with hexane, ethyl acetate and methanol. The hexane extract showed 97 percent reduction in colony-forming units (CFU) at 100 microg/ml. The hexane extract was

The oral bioavailability of vasicine (1) was investigated in hard gelatin capsules of lyophilized Vasa Swaras (aqueous extract of Adhatoda vasica Nees.,Fam.: Acanthaceae) The rat pharmacokinetic profile of lyophilized Vasa Swaras, Vasa Swaras, vasicine (1) (chief marker compounds of A. vasica) and a

The benzylamines, bromhexine and ambroxol, widely used as mucolytics, have a pH-dependent growth-inhibitory effect on Mycobacterium tuberculosis. As these compounds are concentrated in macrophages, they might exert a clinically useful effect on intracellular tubercle bacilli. This, combined with
