In a screening program for new agrochemicals from Chinese medicinal herbs and wild plants, essential oil of Homalomena occulta (Lour.) Schott rhizome was found to possess strong nematicidal activity against the root-knot nematodes, Meloidogyne incognita (Kofoid and White) Chitwood. The essential oil of H. occulta rhizome was extracted via hydrodistillation and investigated by gas chromatography...

The importance of clean and solvent-free pharmaceuticals, nutraceuticals and other allied healthcare (food) products are continuously increasing towards meeting the challenges posed by International regulatory and consumer requirements. The issue of residual solvents in healthcare products is well known requiring consideration, and currently, nutraceutical products derived from medicinal and ar...

The molluscicidal activity of leaf and rhizome extracts of Iris germanica L. (var. alba) against Biomphalaria alexandrina snails was evaluated and the rhizome extracts were found to be the most potent. Activity-guided fractionation revealed that the chloroform extract showed the highest molluscicidal activity (LC90 = 1.26 mg/l) among the tested extracts of the rhizomes. Fraction B prepared from...

Alpinia officinarum is a rhizome belonging to the family zingeberaeceae. Hydro alcoholic extract by hot and cold maceration and methanol extract by percolation process Qualitative phytochemical analysis of extract of Alpinia officinarum rhizome showed a majority of the compound including tannins, alkaloids, flavonoids and saponins. Hydroalcoholic extract prepared by hot maceration process was f...

Two new species of Curcuma, C. sattayasaii A. Chaveerach & R. Sudmoon and C. zedoaroides A. Chaveerach & T. Tanee with rhizomes traditionally used for many decades as cobra-bite antidotes are described and illustrated. Curcuma sattayasaii is similar to C. longa L., but differs in rhizome horizontally branching on ground; coma bracts pinkish-white or pinkish-pale green; corolla pale yellow with ...

An endophytic bacterium was isolated from Acorus calamus rhizomes, which is an important medicinal plant. The rhizome is an important medicinal nutrient source of microorganisms, in the rhizosphere. The isolate was evaluated for various biochemical tests. Further the isolate PPAU01 was subjected to 16S rRNA sequencing. The isolate was identified as Enterobacter cloacae sub sp dissolvens which w...

Abstract Rhizome of Polygonatum sibiricum is both a renowned traditional Chinese remedy and commonly consumed delicacy. Due to the escalating demand excessive overexploitation, there has been growing interest in artificial cultivation this plant recent years. To assess therapeutic benefits artificially cultivated P. , it crucial identify classify its phytochemical components, which are primary ...

The plant Nardostachys jatamansi DC. (Valerianaceae) is a critically endangered rhizome bearing medicinal herb. It is restricted to specialized habitats in high altitudes of Himalaya ranging from 3000 to 5000m. Nardostachys jatamansi has been traditionally employed in treatment of wide range of disorders including nervous system, digestive system, circulatory system, respiratory system, urinary...

A preparative gas chromatography (pGC) method was developed for the separation of volatile components from the methanol extract of Curcuma rhizome. The compounds were separated on a stainless steel column packed with 10% OV-101 (3 m × 6 mm, i.d.), and then, the effluent was split into two gas flows. One percent of the effluent passed to the flame ionization detector (FID) for detection and the ...
