Characterization of flavonoids in the ethomedicine Fordiae Cauliflorae Radix and its adulterant Millettiae Pulchrae Radix by HPLC-DAD-ESI-IT-TOF-MSn.

ABSTRACT: Fordiae Cauliflorae Radix (FC, the root of Fordia cauliflora Hemsl) and Millettiae Pulchrae Radix [MP, the root of Millettia pulchra (Benth.) Kurz var. laxior (Dunn) Z. Wei], which go under the same local name of "Daluosan", have long been used in Southern China for the treatment of stroke, paralysis, dementia in children, Alzheimer's disease and other diseases. The same local name and similar functions always confuse users. To further utilize these two ethnodrugs and identify them unambiguously, an HPLC-DAD-ESI-IT-TOF-MSn method was developed to separate and characterize the flavonoids in FC and MP. A total of 41 flavonoids were detected, of which six compounds were identified by comparing their retention time and MS data with those of the reference standards, and the others were tentatively identified based on their tandem mass spectrometry data obtained in the positive ion detection mode. Nineteen of these characterized compounds are reported from these two plants for the first time.

Project description:Danggui Buxue Tang (DBT) is a Traditional Chinese Medicine (TCM) formula primarily used to treat symptoms associated with menopause in women. Usually, DBT is composed of one portion of Radix Angelicae Sinensis (RAS) and five portions of Radix Astragali (RA). Clinically, Radix Hedysari (RH) is sometimes used by TCM physicians to replace RA in DBT. In order to verity whether the chemical constituents of the DBT1 (RA:RAS = 5:1, w/w) and DBT2 (RH:RAS = 5:1, w/w) share similarities the chemical profiles of the two DBTs crude extracts and urine samples were analyzed and compared with the aid of HPLC-DAD-ESI-IT-TOF-MSn, which determines the total ion chromatogram (TIC) and multi-stage mass spectra (MSn). Then, the DBT1 and DBT2 were identified and compared on the basis of the TIC and the MSn. In the first experiment (with crude extracts), 69 compounds (C1-C69) were identified from the DBT1; 46 compounds (c1-c46) were identified from the DBT2. In the second experiment(with urine samples), 44 compounds (M1-M44) were identified from the urine samples of rats that had been administered DBT1, and 34 compounds (m1-m34) were identified from the urine samples of rats that had been administered DBT2. Identification and comparison of the chemical compositions were carried out between the DBT1 and DBT2 of the crude extracts and urine samples respectively. Our results showed that the two crude extracts of the DBTs have quite different chemical profiles. The reasons for their differences were that the special astragalosides in DBT1 and the isoflavonoid glycosides formed the malonic acid esters undergo single esterification and acetyl esters undergo acetylation in DBT1. In contrast, the urine from DBT1-treated rats strongly resembled that of DBT2-treated rats. These metabolites originate mainly from formononetin, calycosin and their related glycosides, and they were formed mainly by the metabolic process of reduction, deglycosylation, demethylation, hydrogenation and sulfation. The HPLC-DAD-ESI-IT-TOF-MSn method was successfully applied for the rapid chemical profiles evaluation of two DBTs and their related urine samples.
