Legume sprouts are a fresh nutritive source of phytochemicals of increasing attention worldwide owing to their many health benefits. Nuclear magnetic resonance (NMR) was utilized for the metabolite fingerprinting of 4 major legume sprouts, belonging to family Fabaceae, to be exploited for quality control purposes. Thirty-two metabolites were identified belonging to different classes, i.e., fatty acids, sugars, amino acids, nucleobases, organic acids, sterols, alkaloids, and isoflavonoids. Quantitative NMR was employed for assessing the major identified metabolite levels and multivariate data analysis was utilized to assess metabolome heterogeneity among sprout samples. Isoflavones were detected exclusively in Cicer sprouts, whereas Trigonella was characterized by 4-hydroxyisoleucine. Vicia sprouts were distinguished from other legume sprouts by the presence of L-Dopa versus acetate abundance in Lens. A common alkaloid in all sprouts was trigonelline, detected at 8–25 µg/mg, suggesting its potential role in legume seeds’ germination. Trigonelline was found at highest levels in Trigonella sprouts. The aromatic NMR region data (δ 11.0–5.0 ppm) provided a better classification power than the full range (δ 11.0–0.0 ppm) as sprout variations mostly originated from secondary metabolites, which can serve as chemotaxonomic markers.

Phytochemical Studies

: The fabaceae are rooted in rosaceae pods known as "vegetables" by the early botanists. They are the third family of angiosperms which includes 642 genus divided into about 18,000 species. The fabaceae family is known as the most important family of the ecosystem as it is indispensable in medicine, agriculture, industry and livestock. The Adenocarpus genus has about 50 species that are frequently found in tropical regions of Northern Africa, the southern part of West Europe and in the central and southern Italy. They are used in traditional medicine for the treatment of several diseases: such as microbial infections, leprosy, scabies, acne, malaria and other plants species are used in agriculture as insecticidal properties. Mainly Adenocarpus mannii species is well represented in the tropical regions of North Africa. It occurs in Angola, Mozambique, Malawi, Guinea, South Africa, Tanzania, and Burundi. In Cameroon, it is encountered in South West Region and West Region. Previous phytochemical studies led to the isolation of several classes of compounds such as flavonoids, alkaloids and triterpenes. Several studies report the phytochemical studies on genus Adenocarpus and chemotaxonomic markers of species of this genus. Herein, we outline all the botanical, pharmacological and phytochemical aspects of Adenocarpus mannii. A brief introduction about fabaceae and the genus Adenocarpus has also been included.

The wax hydrocarbon fractions of native Butia and Syagrus species collected from Palms in different regions of the of Rio Grande do Sul state (Brazil) and in Rocha (Uruguay) were analyzed to evaluate their potential as chemotaxonomic markers. The wax was extracted with chloroform and the resulting wax was fractionated by preparative TLC. The hydrocarbon fractions were analyzed by GC-MS. Statistical analyses were completed with the Statistica 5.0 program. The total crude wax yields averaged 0.31% w.w-1 dried leaves for Butia samples and 0.28% for Syagrus samples. The linear hydrocarbons represented on average 15% of the total waxes in the case of Butia samples and 13.7% in Syagrus samples. Hentriacontane and triacontane were the main components of all samples. The comparison of the means showed significant differences among Butia and Syagrus samples, and amongst Butia samples collected in different localities. In the case of the Syagrus collections no consistent groupings could be made. In the case of Butia samples the formation of three groupings could be observed, which were consistent with the species described for their geographical distribution. These results are discussed in the paper.

Abstract From the leaves of Chamaecyparis obtusa several biflavones were isolated and identified, namely: sciadopitysin, ginkgetin, isoginkgetin, podocarpusflavone B, 7,7″-O-dimethylamentoflavone, bilobetin, podocarpusflavone A, and 7-O-methylamentoflavone. The presence of amentoflavone and hinokiflavone was also confirmed. The composition of biflavones in other Chamaecyparis species D Ch. lawsoniana, Ch. thyoides D and cultivar varieties D Ch. pisifera “Squarrosa”, Ch. pisifera “Boulevard” D was compared using the HPLC method. It was stated, that podocarpusflavone A and 7-O-methylamentoflavone in addition to amentoflavone and hinokiflavone may be classified as chemotaxonomic markers of the genus Chamaecyparis

Glucosinolates (GLs) were characterized in the seed and root of Aurinia leucadea (Guss.) C. Koch and A. sinuata (L.) Griseb., and quantified according to the ISO 9167–1 official method based on the HPLC analysis of desulfo-GLs. Glucoalyssin (GAL, 1), glucobrassicanapin (GBN, 2) and glucoberteroin (GBE, 3) were the major GLs identified in A. leucadea and A. sinuata. GC/MS analysis of the volatile fractions obtained after enzyme hydrolysis showed that they mostly contain isothiocyanates (ITCs) originating from the parent GLs. On this basis and from previous reports, C-5 alkyl GLs 1, 2, and 3 can be considered as chemotaxonomic markers of the Aurinia genus.

Phenolic And Flavonoid

Two new prenylated isoflavonoids, namely Erinasone A and Erinasone B along with 19 known secondary metabolites, including twelve isoflavonoids, three polyphenols, one flavonol, two flavanones and three steroids, were isolated from the whole plant (roots and aerial parts) of Erinacea anthyllis. Structures of all isolated compounds were elucidated by spectroscopic analysis, including 1D and 2D NMR (1H, 13C, COSY, HSQC, TOCSY, HMBC and NOESY), mass spectrometry (ESI-MS), UV-Vis, measurement of optical rotation [α]D and by comparison with the literature data. The total phenolic and flavonoid contents were determined in this study. Furthermore, the antioxidant and antibacterial activities of the EtOAc and n-BuOH extracts of E. anthyllis were evaluated. These extracts exhibited moderate antibacterial and antioxidant activities. Their IC50 values were approximately 0.04 mg/mL ( n-BuOH) and 0.037 mg/mL (EtOAc). Consequently, Erinacea anthyllis is a rich source of polyphenolic compounds particularly isoflavonoids used as chemotaxonomic markers for the subfamily Papilionoideae of the family Fabaceae.
