Sintesis Senyawa Koordinasi Astaxanthin Dengan Bantuan Gelombang Ultrasonik

Abstract

SINTESIS SENYAWA KOORDINASI ASTAXANTHIN DENGAN BANTUAN GELOMBANG ULTRASONIK. Astaxanthin merupakan senyawa turunan karotenoid xantofil yang sangat potensial dalam pengobatan kanker. Salah satu upaya meningkatkan aktivitas anti kanker dari astaxanthin adalah dengan menggabungkan senyawa astaxanthin dengan ion logam. Upaya sintesis senyawa koordinasi astaxanthin dengan ion logam Fe 3+ , Mn 2+ , dan Zn 2+ telah dilakukan dengan bantuan gelombang ultrasonik. Panjang gelombang maksimal senyawa kompleks Mn(II)-Astaxanthin adalah 473 nm, Fe(III)-Astaxanthin adalah 355 nm, dan Zn(II)-Astaxanthin adalah 473 nm. Hasil FTIR menunjukan munculnya gugus fungsi khas astaxanthin pada semua kompleks dan munculnya serapan pada 535 cm-1 , untuk kompleks Mn(II)-Astaxanthin, 397 cm-1 untuk Fe(III)-Astaxanthin, dan 535 cm-1 untuk Zn(II)-Astaxanthin yang mengindikasikan adanya ikatan logam dengan atom donor dari Astaxanthin.

“…Table 3 showed that there is stronger stability in the product with an encapsulation ratio of 5 LNC: 1 binder (T 2 ). Compared with the results of research by (Alfanar and Notario 2017), the FTIR results in this study show the emergence of a typical astaxanthin functional group in all complexes and the appearance of absorption at 535 cm −1 , for the Mn (II)astaxanthin complex, 397 cm −1 for Fe (III)-1 astaxanthin, and 535 cm −1 for Zn (II) -astaxanthin which indicates a metal bond with the donor atom of astaxanthin.…”

“…The astaxanthin functional group also appears in the synthesis results where each result of the synthesis shows the C-H, C=C, C=O, and O-H functional groups represent there is astaxanthin in the encapsulated product as a ligand for complex compounds. Astaxanthin is a xanthophyll carotenoid derivative compound that is very potent and has antioxidant activity and can perform complexation with metal ions (Alfanar and Notario 2017). In this study, the encapsulation of the active ingredients was also carried out by using a binder as well as mineral supplementation.…”

Structure Prediction and Ultrasonic Assisted Synthesis of Coordination Compound Cadmium (II) Bromide with N,N’-diethylthiourea Ligand

“…In this study, Cd(II) complexes with detu ligand were synthesized using Cd(II) bromide precursor with the assistance of ultrasonic wave. The use of ultrasonic waves as an alternative in the synthesis of coordination compounds can increase the collision ratio between chemical species and thus influence the success of chemical synthesis (Alfanaar & Notario, 2019). Compared to the conventional method, the used of ultrasound induced extreem conditions that can drive chemical or physical changes during reaction, also promote formation of nanosized particles by the instantaneously formation of a plethora of crystallization nuclei (Etaiw et al, 2021).…”
