“…The amount of this compound varied from 23% to 46%. The compounds identified in this study were also found in B. tripartita L. samples by Tomczykowa et al, 1 while compositions were different: the main compound found by Tomczykowa et al 1 in dried flowers was pcymene (16.6%); in fresh herb -allo-ocimene (38.3%) and β-ocimene (30.6%). In our study allo-ocimene was not found.…”

“…The result may be different due to the different extraction technique. High amount of allo-ocimene is accumulated only in the fresh herb (amount of this compound in dried flower was 2.2%), 1 and may degrade or evaporate during the drying.…”

“…Hydrodistillation is the oldest and the most popular till nowadays. [1][2][3] Likens-Nickerson simultaneous steam distillation extraction, 4 ultrasound-assisted extraction, 5 microwave extraction, 3 Soxhlet extraction, 2 and supercritical fluid extraction 2,4 methods are also used quite often. None of these methods can be considered as ideal; all of them possess advantages and disadvantages, which may have smaller or bigger impact on identification and interpretation of compositional peculiarities of volatile compounds.…”

Recovery of Bidens tripartita L. volatiles using supercritical CO 2 extraction with solid-phase trap was performed in this study. Three aspects were under investigation: the impact of solvent (heptane, methanol or acetonitrile) applied to rinse the analytes from the trap; the impact of the amount of plant material used for extraction; the release of volatiles from plant matrix using multiple extraction. α-Pinene, p-cymene, β-ocimene, and β-elemene were predominant in all extracts prepared in different ways. β-ocimene was the major compound (40-46%) in all extracts regardless of the solvent used. No significant difference in amount of α-pinene was observed when different trap desorption solvents were used, while heptane desorbed significantly higher amounts (12-31%) of other compounds. The volatile composition showed both qualitative and quantitative differences when different amounts of sample material were used. The extraction extent of the main compounds varied between first and repeated extractions.

Essential oils and plant extracts preparation. The essential oil (BTHO) was hydrodistilled (3 h) from the freshly picked flowering aerial parts of the herb (500 g) using a Deryng-type apparatus. The oil (BTFO) was obtained also from dried flower heads (210 g) using the same distillation method [13].Dried and powdered B. tripartita flowers (BF) and herb (BH) were subjected to several extraction procedures: water, FOLIA HISTOCHEMICA ET CYTOBIOLOGICA Vol. 46, No. 3, 2008 pp. 389-393 Antimicrobial and antifungal activities of the extracts and essential oils of Bidens tripartita Abstract: The aim of this study was to determine the antibacterial and antifungal properties of the extracts, subextracts and essential oils of Bidens tripartita flowers and herbs. In the study, twelve extracts and two essential oils were investigated for activity against different Gram-positive Bacillus subtilis, Micrococcus luteus, Staphylococcus aureus, Gram-negative bacteria Escherichia coli, E. coli (β-laktamase+), Klebsiella pneumoniae (ESBL+), Pseudomonas aeruginosa and some fungal organisms Candida albicans, C. parapsilosis, Aspergillus fumigatus, A. terreus using a broth microdilution and disc diffusion methods. The results obtained indicate antimicrobial activity of the tested extracts (except butanolic extracts), which however did not inhibit the growth of fungi used in this study. Bacteriostatic effect of both essential oils is insignificant, but they have strong antifungal activity. These results support the use of B. tripartita to treat a microbial infections and it is indicated as an antimicrobial and antifungal agent, which may act as pharmaceuticals and preservatives.

2D DOSY 1H NMR has proved to be a useful technique in the identification of the molecular skeleton of the four major compounds of ethyl acetate extract of aerial parts of Bidens sulphurea (Asteraceae). The combination of this technique with HPLC, mass spectrometry and other NMR techniques enabled the identification of four flavonoid glycosides: quercetin-3-O-beta-D-galactopyranoside, quercetin-3-O-beta-D-glycopyranoside, quercetin-3-O-alpha-L-arabinofuranoside and quercetin-3-O-beta-D-rhamnopyranoside.
