Abstract
Various novel techniques including ultrasound-assisted extraction, microwave-assisted extraction and supercritical fluid extraction have been developed for the extraction of medicinal plants in order to shorten the extraction time, decrease the solvent consumption, increase the extraction yield, and enhance the quality of extracts. This review was conducted to introduce and compare the conventional soxhlet extraction and the new alternative methods used for the extraction of nutraceuticals from plants.

Abstract [Persian]
مقدمه و هدف: فنآوریهای جدید و مختلفی شامل عصاره گیری همراه با امواج فراصوت، عصارهگیری همراه با امواج مایکروویو و عصاره گیری همراه با مایع فوق بحرانی به منظور استخراج ترکیبات از گیاهان گسترش یافتهاند. این فنآوریها به منظور کاهش دادن مدت زمان عصاره گیری، کاهش میزان حلال مصرفی، افزایش بازده استخراج و تقویت کیفیت عصاره حاصله گسترش یافته اند. در این مقاله به معرفی و مقایسه روش سوکسله و روشهای جایگزین و نوین مورد استفاده در داروسازی پرداخته شده است. برای بهدست آوردن بهترین و موثرترین عصاره، توجه به مواردی از جمله خصوصیات ماده گیاهی، انتخاب حلال مناسب و دقت در مراحل عصارهگیری ضروری بوده و باید در نظر داشت که بازده بالا در عصاره حاصله به معنای بازده بالای ترکیب مورد نظر در عصاره نمیباشد.
توصیه کاربردی: در روش عصارهگیری با استفاده از امواج فراصوت نفوذ حلال به بافت گیاهی به خوبی صورت میگیرد و در مقایسه با سایر روشها این روش از کارآیی و سرعت بالاتری برخوردار است.
