1. An optimization approach of dynamic maceration of Centella asiatica to obtain the highest content of four centelloids by response surface methodology
ABSTRACT Centella asiatica (L.) Urb., Apiaceae, is commonly used as food, food supplement, and medicine. Development of the extraction process to obtain the high extent of the active compound is necessary. So, the response surface methodology was used in this work to optimize the dynamic maceration of C. asiatica to obtain the highest content of the four cen

3. Turbo-extraction of glycosides from Stevia rebaudiana using a fractional factorial design
ABSTRACT Stevia rebaudiana (Bertoni) Bertoni, Asteraceae, leaf extract has recently called the attention of food industry as a proposal for natural sweetener. The sweet flavor is attributed to the glycosides, in especial stevioside and rebaudioside A, which are the plant main chemical markers. The aim of the work reported here was to optimize the turbo-extra

4. Sperm Quality and Testicular Histomorphometry of Wistar Rats Supplemented with Extract and Fractions of Fruit of Tribulus terrestris L.
ABSTRACT The aim of this study was to assess the sperm quality and testicular histomorphometry of Wistar rats supplemented with extract and fractions of fruits of Tribulus terrestris L. The ethanolic extract was obtained by dynamic maceration of spray-dried fruit. This extract was fractionated by liquid-liquid partition, using increasing polarity solvents. T

5. Cat's claw oxindole alkaloid isomerization induced by common extraction methods
Cat's claw oxindole alkaloids are prone to isomerization in aqueous solution. However, studies on their behavior in extraction processes are scarce. This paper addressed the issue by considering five commonly used extraction processes. Unlike dynamic maceration (DM) and ultrasound-assisted extraction, substantial isomerization was induced by static maceratio

7. Spray-dried extracts from Syzygium cumini seeds: physicochemical and biological evaluation
Aqueous extract from seeds of Syzygium cumini (L.) Skeels, Myrtaceae, obtained by dynamic maceration was spray-dried and characterized by its physico-chemical and antihyperglycaemic action. The extract showed to possess high amount of polyphenols, significant in vitro free radical scavenger activity using the DPPH method and an antihyperglycaemic effect in a

8. Dynamic maceration of Copaifera langsdorffii leaves: a technological study using fractional factorial design
The Copaifera langsdorffii Desf., Fabaceae, is a Brazilian native tree, known as copaiba, which oil is commonly used in folk medicine as muscle relaxant, wound healing, antiseptic and anti-inflammatory to respiratory and urinary tracts. Despite of the wide use of the oil of Copaifera species, scientific works related to the study of its leaves are rarely fou

9. Optimization of the extraction of curcumin from Curcuma longa rhizomes
The aim of this work was to study the effect of dynamic maceration factors upon the curcumin content of Curcuma longa L., Zingiberaceae, extracts and to determine the optimum set of parameters for the extraction of curcumin using a 2(5) full factorial design and the response surface methodology. Under the established conditions, the content of soluble solids

10. Bioactive compounds in Bidens pilosa L. populations: a key step in the standardization of phytopharmaceutical preparations
The total flavonoid content (TFC), total polyphenols content (TPC), and in vitro antioxidant activity (AA) of six Bidens pilosa L., Asteraceae, populations harvested from different localities were evaluated in this work. The plants were separated in roots, stems, and leaves/flowers, and the influence of extraction methods was investigated.Areversed-phase hig

12. DEVELOPMENT AND STANDARDIZATION OF Rapanea ferruginea MEZ. (MIRSINACEAE) DRY EXTRACT OBTAINED FROM SPRAY DRYING AND EVALUATION IN VIVO OF ITS ANTINOCICEPTIVE ACTIVITY / DESENVOLVIMENTO E PADRONIZAÇÃO DE EXTRATO SECO DE Rapanea ferruginea MEZ. (MIRSINACEAE) OBTIDO POR SPRAY DRYING E AVALIAÇÃO IN VIVO DA ATIVIDADE ANTINOCICEPTIVA
Rapanea ferruginea is a pantropical species that grows in various parts of Brazil. It is popularly known in Brazil as canela-azeitona or capororoca. Studies carried out in past by the NIQFAR research group have shown that this plant presents biological effects, including antiinflamatory, hypoglicemic and analgesic effects. This work seeks to develop and stan
