    Extracts from Field Margin Weeds Provide Economically Viable and Environmentally Benign Pest Control Compared to Synthetic Pesticides.[Pubmed: 26599609 ]
    Plants with pesticidal properties have been investigated for decades as alternatives to synthetics, but most progress has been shown in the laboratory. Consequently, research on pesticidal plants is failing to address gaps in our knowledge that constrain their uptake. Some of these gaps are their evaluation of their efficacy under field conditions, their economic viability and impact on beneficial organisms.
    METHODS AND RESULTS:
    Extracts made from four abundant weed species found in northern Tanzania, Tithonia diversifolia, Tephrosia vogelii, Vernonia amygdalina and Lippia javanica offered effective control of key pest species on common bean plants (Phaseolus vulgaris) that was comparable to the pyrethroid synthetic, Karate. The plant pesticide treatments had significantly lower effects on natural enemies (lady beetles and spiders). Plant pesticide treatments were more cost effective to use than the synthetic pesticide where the marginal rate of return for the synthetic was no different from the untreated control, around 4USD/ha, compared to a rate of return of around 5.50USD/ha for plant pesticide treatments. Chemical analysis confirmed the presence of known insecticidal compounds in water extracts of T. vogelii (the rotenoid deguelin) and T. diversifolia (the sesquiterpene lactone Tagitinin A). Sesquiterpene lactones and the saponin vernonioside C were also identified in organic extracts of V. amygdalina but only the saponin was recorded in water extracts which are similar to those used in the field trial.
    CONCLUSIONS:
    Pesticidal plants were better able to facilitate ecosystem services whilst effectively managing pests. The labour costs of collecting and processing abundant plants near farm land were less than the cost of purchasing synthetic pesticides.

    Phytotoxins from Tithonia diversifolia.[Pubmed: 25879678 ]
    Tithonia diversifolia (Mexican sunflower) is a dominant plant of the Asteraceae family, which suggests it produces allelochemicals that interfere with the development of surrounding plants. The study described herein was conducted to identify the compounds that have phytotoxic activity in T. diversifolia extracts.
    METHODS AND RESULTS:
    Ethyl acetate extracts of the leaves, stems, and roots showed significant inhibition of wheat coleoptile growth, and the leaf extract had similar inhibitory effects to a commercial herbicide. Fourteen compounds, 12 of which were sesquiterpene lactones, have been isolated. Two sesquiterpene lactones are reported for the first time and were isolated as an inseparable mixture of 8β-O-(2-methylbutyroyl)tirotundin (4) and 8β-O-(isovaleroyl)tirotundin (5). Their structures were determined by spectroscopic analysis, including NMR techniques and mass spectrometry. The sesquiterpene lactones 1β-methoxydiversifolin (6), Tagitinin A (7), and tagitinin C (8) were the major products identified.
    CONCLUSIONS:
    These compounds were active on etiolated wheat coleoptiles, seed germination, and the growth of STS and weeds. The phytotoxic activity shown by these sesquiterpene lactones indicates that they are the compounds responsible for the activity exhibited by the initial extracts.

    Storage: Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months(2-8C).

    Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20C. Generally, these will be useable for up to two weeks. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.

    Need more advice on solubility, usage and handling? Please email to: service@chemfaces.com

    After receiving: The packaging of the product may have turned upside down during transportation, resulting in the natural compounds adhering to the neck or cap of the vial. take the vial out of its packaging and gently shake to let the compounds fall to the bottom of the vial. for liquid products, centrifuge at 200-500 RPM to gather the liquid at the bottom of the vial. try to avoid loss or contamination during handling.

    Sesquiterpene lactones from Tithonia diversifolia act as peroxisome proliferator-activated receptor agonists.[Pubmed: 22424975 ]
    Tithonia diversifolia is a well-known traditional Chinese medicine treating diabetes, hepatitis, and hepatocarcinoma but its molecular mechanism is not fully understood. Peroxisome proliferator-activated receptors (PPARs) α and γ are members of nuclear receptor superfamily. Their agonists are prescribed as antihyperlipidemic and antihyperglycemic drugs now.
    METHODS AND RESULTS:
    In this study, sesquiterpene lactones, tirotundin and Tagitinin A, were isolated from T. diversifolia and evaluated for their activity against PPARs by the transient transfection reporter assay. Tirotundin and Tagitinin A transactivated PPARγ dependent promoters including PPRE (PPARγ response element), SHP, and ABCA1 gene promoters in dose-dependent manner. Furthermore, the fluorescence polarization competitive binding assay showed that tirotundin (IC(50)=27 μM) and Tagitinin A (IC(50)=55 μM) enhanced PPARγ transactivation activity by directly binding to PPARγ ligand binding domain. Additionally, they stimulated the transactivation of PPARα dependent SULT2A1 gene promoter by 2.3-fold of vehicle effect at 10 μM.
    CONCLUSIONS:
    These results highly indicated that tirotundin and Tagitinin A are the active components of T. diversifolia to exert anti-diabetic effect through PPARγ pathway. Moreover, these sesquiterpene lactones behaved as PPARα/γ dual agonists so they might be useful as the potential herbal treatment for diabetes.

    Absolute stereochemistry of tagitinin A.[Reference: WebLink]

    METHODS AND RESULTS:
    Single crystal X-ray diffraction studies of the melampolide (3a) obtained from the reaction of Tagitinin A (1a) with chlorotrimethylsilane and sodium iodide strongly suggest that C-4 methyl in Tagitinin A is α-oriented.
