Publikováno v: Phytochemistry. 196

Kunzea (Myrtaceae) trees and shrubs, generally called kānuka, grow across most of Aotearoa/New Zealand (NZ). With the exception of K. sinclairii, an offshore island endemic, kānuka had been treated as an Australasian species K. ericoides. However,

Mātauranga-guided screening of New Zealand native plants reveals flavonoids from kānuka (Kunzea robusta) with anti-Phytophthora activity

Autor: Monica L. Gerth, Chris Pairama, Elaine J. Burgess, Amanda Black, Ian Mitchell, Nigel B. Perry, Scott A. Lawrence, Wayne M. Patrick

Kauri is an ecologically important and culturally treasured tree species in Aotearoa New Zealand. It is under threat from the pathogenic oomycete Phytophthora agathidicida, which causes kauri dieback disease. We hypothesised that mātauranga Māori (

Publikováno v: Planta Medica. 81:1163-1168

Cytotoxic amides have been isolated from the fruits of the endemic New Zealand medicinal plant kawakawa, Macropiper excelsum (Piperaceae). The main amide was piperchabamide A and this is the first report of this rare compound outside the genus Piper.

Raman Spectroscopy of Fish Oil Capsules: Polyunsaturated Fatty Acid Quantitation Plus Detection of Ethyl Esters and Oxidation

Autor: Daniel P. Killeen, Keith C. Gordon, Susan N. Marshall, Nigel B. Perry, Elaine J. Burgess

Publikováno v: Journal of agricultural and food chemistry. 65(17)

Fish oils are the primary dietary source of ω-3 polyunsaturated fatty acids (PUFA), but these compounds are prone to oxidation, and commercial fish oil supplements sometimes contain less PUFA than claimed. These supplements are predominantly sold in

Regiospecific Analyses of Triacylglycerols of Hoki (Macruronus novaezelandiae) and Greenshell™ Mussel (Perna canaliculus)

Autor: Elaine J. Burgess, Susan N. Marshall, Nigel B. Perry, Matthew R. Miller

Publikováno v: Journal of the American Oil Chemists' Society. 88:509-516

The lipid profiles of the two most important New Zealand marine oil sources were investigated, with particular attention to the regioisomeric compositions of triacylglycerides (TAG), using 13C-nuclear magnetic resonance analysis. Oils from hoki (Macr

Sesquiterpene Lactones inArnica montana: Helenalin and Dihydrohelenalin Chemotypes in Spain

Autor: Elvira López Mosquera, Roger P. Littlejohn, Rosa Romero Franco, Manuel Rodríguez Guitián, Nigel B. Perry, Elaine J. Burgess, Bruce M. Smallfield, Nigel I. Joyce

Publikováno v: Planta Medica. 75:660-666

An analytical RPLC method for sesquiterpene lactones in Arnica montana has been extended to include quantitative analyses of dihydrohelenalin esters. LC-ESI-MS-MS distinguished the isomeric helenalin and dihydrohelenalin esters. The dihydrohelenalin

JAK2 and AMP-kinase inhibition in vitro by food extracts, fractions and purified phytochemicals

Autor: Tony K. McGhie, Elaine J. Burgess, Janine M. Cooney, Nigel B. Perry, Wendy A. Smith, Tania M. Trower, Harry Martin, Erika de Guzman, Rona C. M. Lunken

Publikováno v: Foodfunction. 6(1)

We have identified a range of food phytochemicals that inhibit Janus Kinase 2 (JAK2) and Adenosine Monophosphate Kinase (AMPK). A mutated and dysregulated form of JAK2, a tyrosine kinase, is associated with several diseases including Crohn's disease.

A Silychristin Isomer and Variation of Flavonolignan Levels in Milk Thistle (Silybum marianum) Fruits

Autor: Nigel B. Perry, Wendy A. Smith, Denis R. Lauren, Elaine J. Burgess, Richard J. Martin

Publikováno v: Planta Medica. 71:877-880

A new natural product has been isolated from silymarin, the hepatoprotective extract of milk thistle (Silybum marianum) fruits. This was shown by NMR spectroscopy to be silychristin B (8), a diastereoisomer of the known silychristin (7). Levels of th
