Antimicrobial properties of star anise (Illicium verum Hook f).
Phytotherapy research : PTR, 2002Co-Authors: Parimal C. Sen, Arun Baran BanerjeeAbstract:Star anise (Illicium verum Hook f) has been shown to possess potent antimicrobial properties. Chemical studies indicate that a major portion of this antimicrobial property is due to anethole present in the dried fruit. Studies with isolated anethole (compared with standard anethole) indicated that it is effective against bacteria, yeast and fungal strains.

AGE AND GROWTH OF BLACK-BELLIED ANGLERFISH Lophius budegassa (Spinola, 1807) FROM THE CENTRAL AEGEAN SEA, TURKEY
'Walter de Gruyter GmbH', 2020Co-Authors: Şenbahar, Ahmet Mert, Özaydin OkanAbstract:U svrhu utvrđivanja dobi i rasta, ukupno 558 primjeraka grdobine žutke Lophius budegassa (Spinola, 1807) je uzorkovano povlačnim ribarskim mrežama pri komercijalnom ribolovu u srednjem Egejskom moru u razdoblju od rujna 2017. do kolovoza 2018. Dob se određivala brojanjem prstena rasta na poprečnom presjeku Illiciuma (modificirane prve dorzalne peraje). Očitavanjem Illiciuma jedinke su kategorizirane u dobne skupine od II-XI. Vrijednosti totalne dužine i mase su se kretale između 12,0 – 65,0 cm, odnosno 24,5 – 4682,0 g. Von Bertalanffy parametri rasta procijenjeni su za mužjake, ženke i kombinirani spol L. budegassa. Također, rezultati su uspoređeni s prethodnim istraživanjima.A total of 558 specimens of black-bellied anglerfish Lophius budegassa(Spinola, 1807) were collected by the vessels engaged in commercial trawl fishing in the Central Aegean Sea between September 2017 and August 2018 in order to determine age and growth. Ageing was based on growth ring counts of transverse sections of the Illicium (first ray of the dorsal fin). By reading the Illicium, individuals were found within II-XI age groups. Total lengths and weights ranged between 12.0 – 65.0 cm and 24.5 – 4682.0 g, respectively. Von Bertalanffy growth parameters were estimated for males, females and combined sexes of L. budegassa. The results are compared with previous studies

distinguishing chinese star anise from japanese star anise using thermal desorption gas chromatography mass spectrometry
Journal of Agricultural and Food Chemistry, 2009Co-Authors: Melaniejayne R Howes, Geoffrey C Kite, Monique S J SimmondsAbstract:The volatile compounds from the pericarps of Illicium anisatum L., Illicium brevistylum A.C.Sm., Illicium griffithii Hook.f. & Thomson, Illicium henryi Diels, Illicium lanceolatum A.C.Sm., Illicium majus Hook.f. & Thomson, Illicium micranthum Dunn, and Illicium verum Hook.f. were examined by thermal desorption-gas chromatography-mass spectrometry (TD-GC-MS). The volatiles desorbed from the pericarps of I. verum (Chinese star anise), the species traded for culinary purposes, were generally characterized by a high proportion of (E)-anethole (57.6-77.1%) and the presence of foeniculin; the latter was otherwise only detected in the pericarps of I. lanceolatum. In the pericarps of all other species analyzed, the percentage composition of (E)-anethole was comparatively lower (

Rapid control of Chinese star anise fruits and teas for neurotoxic anisatin by Direct Analysis in Real Time high resolution mass spectrometry.
Journal of chromatography. A, 2012Co-Authors: Y. Shen, Teris A. Van Beek, F.w. Claassen, Han Zuilhof, Bo Chen, Michel W. F. NielenAbstract:After ingestion, products containing Chinese star anise (Illicium verum) contaminated or adulterated with Japanese star anise (Illicium anisatum) or other Illicium species, can cause epilepsy, hallucinations, and nausea due to the rare neurotoxic sesquiterpene dilactone anisatin that is present in Japanese star anise. Thus a rapid, simple and unambiguous method for distinguishing between the morphologically similar Chinese star anise and toxic Japanese star anise is important for food safety issues. Direct Analysis in Real Time (DART) ambient ionisation coupled with orbitrap high resolution mass spectrometry allowed the recording of mass spectra of anisatin in solid star anise fruits in seconds without any prior sample pretreatment. Spectra could be obtained in both positive ([M+NH(4)](+) at m/z 346.1496, C(15)H(24)NO(8)) and negative mode ([M-H](-) at m/z 327.1074, C(15)H(19)O(8)) and gave the same outcome provided a mass resolution of at least 27,000 is available. The anisatin signal was typically >1000 times larger in Japanese star anise than in Chinese star anise thus allowing an unequivocal qualitative determination. Herbal teas containing star anise fragments too small to be visually recognised, could be analysed by preparing a tea in 6 min and subsequently sampling ∼2 μL of tea on a glass rod. None of the 8 investigated retail teas contained significant quantities of anisatin. Spiking a complex herbal tea containing Chinese star anise with an equally concentrated tea prepared from Japanese star anise provided a linear calibration curve (R(2) ≥ 0.995) after normalising on a native constituent of Chinese star anise (standard addition method). This showed that adulteration down to 1% (w/w) is still measurable. Compared with existing PCR, TLC, GC-MS and HPLC-ESI-MS/MS procedures, the proposed DART-HRMS procedure is faster and simpler and moreover measures the actual biotoxin.

Neurotoxicities in infants seen with the consumption of star anise tea.
Pediatrics, 2004Co-Authors: Diego Ize-ludlow, Sean Ragone, Isaac S. Bruck, Jeffrey N. Bernstein, Michael Duchowny, Barbara M. Garcia PeñaAbstract:Chinese star anise (Illicium verum Hook f.) is a well-known spice used in many cultures. Many populations use it as a treatment for infant colic. Japanese star anise (Illicium anisatum L), however, has been documented to have both neurologic and gastrointestinal toxicities. Recently, concern has been raised regarding the adulteration of Chinese star anise with Japanese star anise. We report 7 cases of adverse neurologic reactions in infants seen with the home administration of star anise tea. In addition, we have found evidence that Chinese star anise has been contaminated with Japanese star anise. More strict federal regulation of the import of star anise into the United States is warranted. Star anise tea should no longer be administered to infants because of its potential danger in this population.
