Cov khoom:
4-Methoxybenzaldehyde, tseem hu ua p-Anisaldehyde, yog ib qho tshuaj tsw qab aldehyde nrog cov tshuaj formula C₈H₈O₂. Nws nta lub nplhaib benzene hloov nrog ib pawg methoxy (-OCH₃) thiab pawg formyl (-CHO) ntawm txoj hauj lwm para. Nws yog cov kua uas tsis muaj xim nrog lub qab zib, paj aroma reminiscent ntawm anise thiab feem ntau pom muaj nyob rau hauv ntau yam nroj tsuag, xws li vanilla taum thiab anise. Lub compound yog siv nyob rau hauv cov tshuaj tsw qab kev lag luam vim nws cov ntxhiab tsw qab ntxiag thiab ua hauj lwm raws li ib tug intermediate nyob rau hauv cov organic synthesis.
Cov hauv qab no yog cov chaw siv ntawm cov khoom:
Siv:
Hauv kev lag luam tshuaj tsw qab thiab tsw: dav siv hauv daim teb no.
Raws li qhov nruab nrab: Ib qho tseem ceeb nruab nrab hauv kev sib txuas ntawm lwm cov organic tebchaw, naj hoom thiab tshuaj xws li tshuaj tiv thaiv kab mob. Kuj tseem siv rau hauv kev npaj ntawm agrochemicals, dyes thiab yas additives.
Nyob rau hauv nyias txheej chromatography (TLC): Ib qho kev daws ntawm para-anisaldehyde nrog cov kua qaub thiab ethanol yog siv los ua cov stain hauv TLC, uas muab kev txheeb xyuas yooj yim ntawm cov tebchaw sib txawv.
Muaj peev xwm kho tau tus kab mob: Ib qho sib txuas sib txuas, 2-hydroxy-4-methoxybenzaldehyde (HMB), qhia tau tias muaj peev xwm tiv thaiv methicillin-resistant Staphylococcus aureus (MRSA). Ntawm sub-lethal concentrations, HMB inhibits zus tau tej cov staphyloxanthin, ib tug virulence yam tseem ceeb rau MRSA ciaj sia taus thiab tsis kam mus rau tib neeg lub cev tiv thaiv kab mob. HMB kev kho mob kuj zoo li ua rau MRSA rhiab heev rau cov kev cuam tshuam ntawm cov qe ntshav dawb thiab lwm yam kev tiv thaiv kab mob, qhia tias nws yuav yog ib tus neeg sib tw pheej hmoo rau kev tshawb fawb thiab kev loj hlob ntxiv raws li kev kho mob MRSA.
Cov hauv qab no yog cov chaw siv ntawm cov khoom:
Muaj feem cuam tshuam:
Ua cov txheej txheem cuam tshuam nrog vanillin, 4-anisaldehyde yog siv dav hauv kev lag luam tshuaj tsw qab thiab tsw. Nws kuj yog siv los ua ib qho nruab nrab hauv kev sib txuas ntawm lwm cov tebchaw tseem ceeb hauv cov tshuaj thiab tshuaj tsw qab. Qhov cuam tshuam ortho isomer muaj cov ntxhiab tsw ntawm licorice.
Anti-Cancer Properties:
Nws inhibits kev loj hlob ntawm cov qog nqaij hlav qog nqaij hlav hauv cov qauv kev sim thiab inhibits cov qog nqaij hlav qog nqaij hlav los ntawm UV hluav taws xob. 4'-Methoxychalcone kuj tseem yuav pab tau rau kev kho mob glaucoma, qhov twg nws tau pom tias inhibit adenoma thiab neovascularization.
