Natural drugs, not so natural effects: Neonatal abstinence syndrome secondary to 'kratom'.

BACKGROUND: Mitragyna speciosa, also known as kratom, is obtained from the coffee plant family 'Rubiaceae.' Kratom is available in the form of capsules, whole, processed and powdered leaves, and as liquids. Secondary to its 'natural herb' status and opioid effects, it is misconceived to be a safe alternative for the treatment of chronic pain. The use of kratom has increased by tenfold in the United States since 2010. METHODS AND RESULTS: We report a term neonate who was born to a chronic kratom user and required treatment with opiates for neonatal drug withdrawal. CONCLUSION: Physicians should be aware of these herbal supplements and its potential withdrawal effects in newborn which cannot be picked up by the standard toxicology screen.

Determination of trace elements in Rheum moorcroftianum by AAS.

Micro and macro elements such as Zn, Cu, Mn, Fe, Co, Na, K, Ca and Li were detected from Rheum moorcroftianum Royle, a plant used in folk medicines. Altitudinal and seasonal variation of these trace elements in cultivated and wild roots and leaves of R. moorcroftianum were quantified by atomic absorption spectroscopy. The highest concentrations of Zn, Cu, Mn, Fe, Co, Na, K, Ca and Li were found to be 376.0 ± 0.9, 83.0 ± 4.6, 322.0 ± 6.0, 920.0 ± 1.9, 72.0 ± 1.5, 402.0 ± 7.8, 10,235.0 ± 7.0, 12,336.0 ± 2.6 and 59.9 ± 0.3 mg kg(-1), respectively, in all the samples analysed.

Study on the trace elements in Swertia chirayita (Roxb.) H. Karsten.

An attempt has been made to analyze some trace elements and electrolytes like Zn, Cu, Mn, Fe, Co, Na, K, Ca, and Li present in the Swertia chirayita roots and leaves. The concentration of Ca in all the samples was more than 1,346.0 mg/kg and the concentration of other elements was found in the order K > Ca > Fe > Na > Mn > Zn > Co > Cu > Li in different samples of S. chirayita.

Chemical constituents of Asparagus.

Asparagus species (family Liliaceae) are medicinal plants of temperate Himalayas. They possess a variety of biological properties, such as being antioxidants, immunostimulants, anti-inflammatory, antihepatotoxic, antibacterial, antioxytocic, and reproductive agents. The article briefly reviews the isolated chemical constituents and the biological activities of the plant species. The structural formula of isolated compounds and their distribution in the species studied are also given.

Development and physicochemical evaluation of pharmacosomes of diclofenac.

Pharmacosomes are amphiphilic lipid vesicular systems that have shown their potential in improving the bioavailability of poorly water soluble as well as poorly lipophilic drugs. Diclofenac is a poorly water soluble drug and also causes gastrointestinal toxicity. To improve the water solublity of diclofenac, its pharmacosomes (phospholipid complex) have been prepared and evaluated for physicochemical analysis. Diclofenac was complexed with phosphatidylcholine (80%) in equimolar ratio, in the presence of dichloromethane, by the conventional solvent evaporation technique. Pharmacosomes thus prepared were evaluated for drug solubility, drug content, surface morphology (by scanning electron microscopy), phase transition behaviour (by differential scanning calorimetry), crystallinity (by X-ray powder diffraction) and in vitro dissolution. Pharmacosomes of diclofenac were found to be irregular or disc shaped with rough surfaces in SEM. Drug content was found to be 96.2 +/- 1.1%. DSC thermograms and XRPD data confirmed the formation of the phospholipid complex. Water solubility of the prepared complex was found to be 22.1 microg mL-1 as compared to 10.5 microg mL-1 of diclofenac. This improvement in water solubility in prepared pharmacosomes may result in improved dissolution and lower gastrointestinal toxicity. Pharmacosomes showed 87.8% while the free diclofenac acid showed a total of only 60.4% drug release at the end of 10 h of dissolution study.

Distribution and partitioning of phosphorus in solid waste and sediments from drainage canals in the industrial belt of Delhi, India.

Phosphorus is an essential and often limiting nutrient in both marine and freshwater ecosystems. However, its oversupply is of great concern in many environments due to its role in eutrophication. The concentration and distribution of sediment bound phosphorus species not only record its input into the environment, but also suggest their possible sources. It is recognized that the features of phosphorus behaviour have not been extensively studied in urban environments. In this study, phosphorus in solid waste and sediments from drainage canals within the industrial belt of Delhi were fractionated into five operationally defined forms, i.e., exchangeable or loosely sorbed phosphorus (Exch-P), Fe-bound phosphorus (Fe-P), authigenic apatite, CaCO3-bound phosphorus and biogenic apatite (Acet-P), detrital apatite (Det-P) and organic-bound phosphorus (Org-P), in order to assess the potential bioavailability status in these systems.

A new secoiridoid glycoside from Lonicera angustifolia.

A new secoiridoid glycoside, 6'-O-beta-apiofuranosylsweroside (1), together with the known compounds sweroside, loganin, beta-sitosterol, oleanolic acid, ursolic acid and methyl-4-hydroxy benzoate have been identified from the leaves of Lonicera angustifolia. The structure of the new compound has been elucidated on the basis of spectroscopic and chemical evidence.

An A-type proanthocyanidin from Prunus armeniaca.

Roots of Prunus armeniaca yielded a new A-type proanthocyanidin whose structure was assigned as ent-epiafzelechin-3-O-p-hydroxybenzoate-(4alpha-->8, 2alpha-->O-->7)-epiafzelechin (1). The structure of 1 was determined through extensive 1D and 2D NMR studies.
