Flavonoids in Tropical Citrus Species.
Summary of "Flavonoids in Tropical Citrus Species."
HPLC with PDA and MS2 detection was used to identify and quantify flavonoids in the tropical citrus species Citrus microcarpa, Citrus hystrix, Citrus medica var. 1 and 2 and Citrus suhuiensis. Most of these species contained high amounts of flavones, flavanones and dihydrochalcone C- and/or O-glycosides, which were identified on the basis of HPLC retention times, co-chromatography with available authentic standards, absorbance spectra and mass spectral fragmentation patterns. Among the major compounds detected were apigenin-6,8-diC-glucoside, apigenin-8-C-glucosyl-2''-O-rhamnoside, phloretin-3',5'-diC-glucoside, diosmetin-7-O-rutinoside, hesperetin-7-O-neohesperidoside and hesperetin-7-O-rutinoside. Most of the dihydrochalcone and flavone C-glycosides have not previously been detected in tropical citrus. C. microcarpa contained a high amount of phloretin-3',5'-diC-glucoside. Most of the tropical citrus flavanones were neohesperidoside conjugates, which are responsible for imparting a bitter taste to the fruit. Only C. suhuiensis fruit contained a non-bitter rutinoside conjugate.

Medical and Biotech [MESH] Definitions
Citrus Sinensis
A plant species of the genus CITRUS, family RUTACEAE that provides the familiar orange fruit which is also a source of orange oil.
Citrus Aurantiifolia
A plant species of the genus CITRUS, family RUTACEAE that provides the familiar lime fruit. Its common name of lime is similar to the limetree (TILIA).
Citrus Paradisi
A plant species of the genus CITRUS, family RUTACEAE that provides the familiar grapefruit. There is evidence that grapefruit juice inhibits CYTOCHROME P-450 isoform 3A4, resulting in delayed metabolism and higher blood levels of a variety of drugs.
Monarda
A plant genus of the family LAMIACEAE. The common names of beebalm or lemonbalm are also used for MELISSA. The common name of bergamot is also used for Citrus bergamia (CITRUS).
Citrus
A plant genus of the family RUTACEAE. They bear the familiar citrus fruits including oranges, grapefruit, lemons, and limes. There are many hybrids which makes the nomenclature confusing.
