Oleanolic acid, a pentacyclic triterpenoid ubiquitously present in the plant kingdom, is
receiving outstanding attention from the scientific community due to its biological activity …

Supercritical fluid technologies offer a propitious method for drug discovery from natural
sources. Such methods require relatively short processing times, produce extracts with little …

Betulinic acid, a pentacyclic triterpene, is distributed in a variety of plants, such as birch,
eucalyptus and plane trees. It shows a wide spectrum of biological and pharmacological …

Along more than a decade, R&D on supercritical fluid extraction (SFE) of vegetable matrices
has been increasingly reported in the literature. Aiming at portraying the current state of this …

Supercritical fluid extraction (SFE) of plant material with solvents like CO2, propane, butane,
or ethylene is a topic of growing interest. SFE allows the processing of plant material at low …

Ursolic acid (UA) is a pentacyclic triterpenoid widely found in herbs, leaves, flowers and
fruits; update information on the major natural sources or agro-industrial wastes is …

High value-added materials are usually made from low-value materials or wastes.
Producing these materials as by-products along with the main products of any industry or …

This work addresses scientific and techno-economic aspects of supercritical fluid extraction
(SFE) of spent coffee grounds which are of interest under the biorefinery context. Soxhlet …

The reported work aimed at the optimization of operating conditions of the supercritical fluid
extraction (SFE) of spent coffee grounds (SCG) using pure or modified CO 2, with particular …

Over the past few decades, there has been heightened interest in developing modular,
environmentally friendly, sustainable, and recuperative production processes that reuse …
