Chemical Analysis of Dietary Constituents in Rosa roxburghii and Rosa sterilis Fruits

Abstract

Both Rosa roxburghii and R. sterilis, belonging to the Rosaceae, are endemic species in Guizhou Province, China. The fruits of these two species are mixed-used as functional food in the region. Aiming to elucidate the phytochemical characteristics of R. roxburghii and R. sterilis fruits, the essential oils and constituents in a methanol extract have been analyzed and compared by GC-MS and UFLC/Q-TOF-MS, respectively. As a result, a total of 135 volatile compounds were identified by GC-MS and 91 components were different between R. roxburghii and R. sterilis fruits; a total of 59 compounds in methanol extracts were identified by UFLC/Q-TOF-MS, including 13 organic acids, 12 flavonoids, 11 triterpenes, nine amino acids, five phenylpropanoid derivatives, four condensed tannins, two stilbenes, two benzaldehyde derivatives and one benzoic acid derivative; and nine characteristic compounds were found between R. roxburghii and R. sterilis fruits. This systematic study plays an important role for R. roxburghii and R. sterilis fruits in the product development.

Screening of Combinatorial Quality Markers for Natural Products by Metabolomics Coupled With Chemometrics. A Case Study on Pollen Typhae

“…Therefore, the identification of this kind of compounds will play a pivotal role in elucidating the mechanism of PT. According to the previous research, organic acids showed good MS response in negative ion mode rather than positive ion mode with the characteristic fragment ions such as CO 2 (44 Da), CO (28 Da), and H 2 O (18 Da), which helped rapidly identify compounds (Figure S1B ; Liu et al, 2016 ).…”

Analysis of the Total Biflavonoids Extract from Selaginella doederleinii by HPLC-QTOF-MS and Its In Vitro and In Vivo Anticancer Effects

“…High-resolution tandem mass spectrometry can provide elemental composition information of both the precursor and product ions, which is very helpful in fragmentation pattern deduction [ 12 , 13 , 14 , 15 , 16 , 17 ] and structural characterization for natural products, such as polyphenols [ 18 , 19 ], flavonoids [ 19 , 20 , 21 ], alkaloids [ 22 ], and terpenes [ 18 , 21 ]. Using this technique, the fragmentation behaviors in the positive ion mode of biflavonoids in the Selaginella genus have been studied [ 23 , 24 ], which will aid in the elucidation of unknown compounds of this kind.…”

The Anti-Aging Activities against Oxidative Damages of <i>Rosa roxburghii</i> and Multi-Fruit Concentrate Drink

“…Nature fruits provide the natural nutrients required for neutralizing oxidation attack and attenuating inflammation [21]. R. roxburghii is a native fruit in Southern China and has been used as medicine since 1765 [22]. It is rich in polyphenols, flavonoids, organic acids, triterpenes, amino acids, polysaccharides and essential oils [23,24,25].…”
