Comparative analyses of flavonoid content in Moringa oleifera and Moringa ovalifolia with the aid of UHPLC-qTOF-MS fingerprinting

Author: Makita, C ; Chimuka, L ; Steenkamp, Paul ; Cukrowsk, E ; Madala, E Date: Jul 2016 Moringa species are multipurpose plants with nutritional, medicinal and industrial benefits. The flavonoids content of Moringa oleifera and Moringa ovalifolia was studied using an Ultra high-performance liquid chromatography coupled with ... Read more
Distribution patterns of flavonoids from three Momordica species by ultra-high performance liquid chromatography quadrupole time of flight mass spectrometry: a metabolomic profiling approach

Author: Madala, NE ; Piater, L ; Dubery, I ; Steenkamp, Paul A Date: Aug 2016 Plants from the Momordica genus, Curcubitaceae, are used for several purposes, especially for their nutritional and medicinal properties. Commonly known as bitter gourds, melon and cucumber, these plants are characterized by a bitter taste ... Read more
Flavonoids of Steganotaenia araliacea

Author: Omolo, JJ ; Maharaj, V ; Naidoo, Dashnie ; Malebo, HM ; Mtullu, S ; Lyaruu, HVM ; Koning, CB Date: 2014 Phytochemical investigation of the stem and bark of Steganotaenia araliacea led to the isolation of two flavonoids. The structures of these compounds were identified as apigenin 4'-glucoside 1 and sophoraflavone B 2 using spectroscopic analysis ... Read more
Perturbation of pharmacologically relevant polyphenolic compounds in Moringa oleifera against photo-oxidative damages imposed by gamma radiation

Author: Ramabulana, T ; Mavunda, RD ; Steenkamp, Paul A ; Piater, LA ; Dubery, IA ; Madala, NE Date: Mar 2016 Oxidative stress is a physiological state associated with almost all biotic and abiotic stresses in plants. This phenomenon occurs due to imbalances which result from the overproduction of reactive oxygen species (ROS). Plants, however, have ... Read more
Pressurized hot water extraction and chemometric fingerprinting of flavonoids from Bidens pilosa by UPLC-tandem mass spectrometry

Author: Gbashi, S ; Njobeh, P ; Steenkamp, Paul A ; Madala, N Date: 2017 The need for greener extraction procedures that are quick and efficient has prompted the evolution of pressurized hot water extraction (PHWE). Here, the extraction of flavonoids from Bidens pilosa was demonstrated using PHWE at 50°C, 100°C ... Read more
Variation in pharmacologically potent rutinoside-bearing flavonoids amongst twelve Moringa oleifera Lam. cultivars

Author: Makita, C ; Madala, NE ; Cukrowska, A ; Abdelgadir, H ; Chimuka, L ; Steenkamp, Paul A ; Ndhlala, AR Date: Sep 2017 Recent evidence has shown that consumption of plants rich in phenolic compounds has health-promoting benefits. Amongst these plants, include Moringa oleifera Lam. (Moringaceae) which has gained significant attention due to its high contingency ... Read more
