“…Results also indicated that curcuminoids concentration is the highest when extracted using UAE with ethanol which was 0.1020 mg/100g. These results correlate well with the findings by Wakte et al [13] and Li et al [14] which reported that ethanol gave the highest curcuminoids content among different extraction solvents as more compounds will be dissolved in a polar organic solvent.…”

Turmeric is one of the prominently use herbal plants due to its diverse beneficial effects especially in Indian medicine. The rhizome part of the turmeric contains valuable compounds which have been said to owe its antimicrobial effects, anti-cancer, anti-inflammatory and enhance wound healing. Due to its short-life span and perishable properties, the conversion of the rhizome into turmeric extract is desirable. Several methods have been used for extraction such as Soxhlet extraction and pressurized liquid extraction (PLE). However, these techniques are tedious, laborious, time consuming and involves the usage of toxic organic solvent, of which safeness of the end product is doubtful. In this study, a rapid, reliable and green extraction method of supercritical fluid extraction (SFE) and ultrasonic assisted extraction (UAE) were used. SFE without modifier has resulted in 0.0006 mg/100 g of curcuminoids concentration and 5.62 % of yield (dry weight basis). UAE using ethanol was able to produce significantly the highest yield (6.40 %, dry weight basis) and the highest curcuminoids concentration (0.1020 mg/100 g). However, SFE was able to produce extract that contain significantly higher major volatile compounds; tumerone, ar-turmerone and curlone. Therefore, this study proves that both extraction methods were able to produce high quality turmeric extract.Keywords: Supercritical fluid extraction, Ultrasonic assisted extraction, percentage yield, curcuminoids, volatile compounds Abstrak Kunyit merupakan tumbuhan herba yang terkenal disebabkan kebaikannya yang pelbagai terutamanya dalam perubatan masyarakat India. Bahagian rizom kunyit mengandungi sebatian berkhasiat yang dipercayai mempunyai kesan antimikrobial, anti-kanser, anti-keradangan dan juga mempercepatkan kadar penyembuhan luka. Disebabkan kitar hidup yang singkat dan ciri mudah rosak yang terdapat pada kunyit, maka penukaran rizom kunyit kepada ekstrak kunyit adalah amat wajar. Beberapa kaedah pengekstrakan telah digunakan seperti pengekstrakan Soxhlet dan pengekstrakan cecair bertekanan (PLE). Bagaimanapun, kaedah-kaedah tersebut amat rumit, sukar, mengambil masa yang lama serta melibatkan penggunaan pelarut organik bertoksik yang menyebabkan keraguan terhadap tahap keselamatan produk iaitu ekstrak kunyit. Di dalam kajian ini, kaedah pengekstrakan yang pantas, dipercayai serta mesra alam iaitu pengekstrakan cecair supergenting (SFE) dan pengekstrakan ultrasonik berbantu (UAE) telah digunakan. SFE tanpa bahan pengubahsuai telah menghasilkan 0.0006 mg/100 g kepekatan kurkuminoids dan 5.62 % hasil ekstrak kunyit (berdasarkan berat kering). UAE menggunakan etanol telah menghasilkan hasil ekstrak yang ketara tinggi (6.40 %, berdasarkan berat kering) dan nilai kepekatan kurkuminoids tertinggi iaitu 0.1020 mg/100 g. Walaubagaimanapun, SFE telah menghasilkan ekstrak yang mengandungi sebatian meruap yang

“…The fruits of P. emblica are highly nutritive, being rich sources of vitamin Traditional methods such as soxhlet and conventional heat-reflux extraction for the recovery of bioactive compounds are laborious (Paviani et al, 2012). They require heavy capital investments, longer extraction time, higher solvent consumption and, therefore, are less friendly to the environment (Barba et al, 2015;Dong et al, 2014;Li et al, 2013;Liao et al, 2015;Wakte et al, 2011). However, these shortcomings can be addressed using a non-ionizing electromagnetic radiation -microwave, that can accelerate extraction (Dahmoune et al, 2015;Pavlović et al, 2013).…”

-The effects of solvent-to-feed (S) and temperature (T) on the kinetics and thermodynamics of the microwave assisted extraction (MAE) of flavonoids from dried fruits of Phyllanthus emblica using water as solvent have been studied. The flavonoid concentration -time data was analyzed using second order and diffusion models. Both the temperature and solvent-to-feed ratio influenced the initial extraction rate and equilibrium concentration. Biot numbers were found to be greater than 50, implying that the internal mass transfer was the rate controlling step in MAE. The composition of extracts obtained using MAE and conventional extraction was similar. However, the effective diffusion coefficients were doubled in MAE when compared to conventional extraction. An empirical correlation was developed to predict the kinetics of MAE as a function of solvent-to-feed ratio and temperature. The study will be of interest to food and pharmaceutical industries.

“…Conventional methods of extracting curcuminoids turmeric generally involve large amount of organic solvents, and can be timeconsuming, low extraction efficiency, not environmentally friendly. Recently environment friendly techniques, such as microwave assisted extraction (Aoki et al, 2005;Mandal et al, 2008;Wakte et al, 2011), ultrasonic assisted extraction (UAE) Wakte et al, 2011), and supercritical fluid (SCF) (Chang et al, 2006;Zabihi et al, 2014) have been reported. Among these methods, UAE has been widely used to extract phytochemicals from many matrixes as an efficient, energy-saving, environmental friendly extraction technique.…”
