A new chromone derivative from Berchemia lineata

Area of Science:

• Phytochemistry
• Natural Product Chemistry
• Pharmacognosy

Background:

• Berchemia lineata (L.) DC. is a plant species with potential medicinal properties.
• Understanding its chemical constituents is crucial for exploring its pharmacological applications.

Purpose of the Study:

• To isolate and identify the chemical constituents from the root of Berchemia lineata.
• To characterize novel compounds and known compounds previously unrecorded in this plant.

Main Methods:

• Extraction of Berchemia lineata root using ethyl acetate.
• Purification using silica gel and RP-C18 silica gel column chromatography.
• Structure elucidation via spectroscopic analysis and preparative High-Performance Liquid Chromatography (HPLC).

Main Results:

• Nine compounds were isolated: 5-hydroxy-7-(2'-hydroxypropyl)-2-methyl-chromone (1), a new chromone derivative (-)-(1'R, 2'S)-erythro-5-hydroxy-7-(1', 2'-dihydroxypropyl)-2-methyl-chromone (2), and known flavonoids naringenin (3), eriodictyol (4), (+)-aromadendrin (5), (+)-taxifolin (6), (+)-catechin (7), (+)-epigallocatechin (8), and quercetin (9).
• Compound 2 represents a novel chromone derivative.
• Compound 1, a known chromone, is reported from this genus for the first time.
• Compounds 3-9, known flavonoids, are isolated from this plant for the first time.

Conclusions:

• The phytochemical investigation of Berchemia lineata root has led to the identification of nine compounds, including one new chromone derivative.
• This study contributes new chemical data on Berchemia lineata, with several compounds being reported for the first time in this species.
• The identified compounds, particularly flavonoids and chromones, warrant further investigation for their potential biological activities.
