Temperature and pressure effects of supercritical carbon dioxide (SCCO2) on the extraction of carotenoids and seed oil from rosehip fruits have been studied. Supercritical fluid extraction (SFE) has shown much potential skills for the isolation of organic compounds from various samples. SFE minimizes sample handling, provides fairly clean extracts, expedites sample preparation and reduces the u...

A rapid and sensitive reversed-phase high-performance liquid chromatographic (RP-HPLC) method has been used for determination of furanocoumarins in methanolic extracts of Peucedanum tauricum Bieb. HPLC separation was performed on a C18 analytical column (250 mm × 4 mm i.d., 5-μm particles) with a methanol–water gradient as mobile phase. A second chromatographic system with an acetonitrile–water...

INTRODUCTION Studies of the medical folklore of Northwestern Argentina are of great ethnomedicine value. The fruits of Geoffroea decorticans (Fabaceae) are used for both culinary and medical purpose (1). The aim of the present work was determined the total phenolic and flavonoid contents and antioxidant activities of extracts of chañar fruits. It was investigated the possible toxic effect on rats.

Liquid chromatography (LC) coupled with UV detection and electrospray ionization (ESI) tandem mass spectrometry (MS/MS) was used for the generation of chemical fingerprints and the identification of phenolic compounds in peumo fruits and aerial parts from southern Chile. Thirty three compounds (19 of these detected in C. alba and 23 in C. monogyna) were identified, mainly flavonoid glycosides, ...

Little data is available in the scientific literature on postharvest changes taking place in Syzygium aqueum fruits, an increasingly popular fruit in the Asian region. In this study the postharvest physico-chemical and mechanical properties, namely, fruit color, weight loss, pulp firmness, total soluble solids, pH and titratable acidity were determined during the postharvest storage period unde...

Observations were made of the effects of several plant regulators, indole-3-acetic acid, kinetin, abscisic acid, and gibberellic acid, as well as of extracts prepared from leaves and fruit stalks on the respiration pattern, ethylene production, and the number of days to ripen of avocado fruits (Persea americana Mill.). These substances were vacuum infiltrated to insure good penetration and dist...

Tribulus terrestris is used as a urinary anti-infective in folk medicine. To validate this use, the in vitro antibacterial activity of methanolic extracts of different parts (fruits, stems plus leaves and roots) of T. terrestris L. growing in Iran was evaluated against four reference bacteria by broth dilution assay and agar diffusion assay. The MIC value of the methanolic extracts of fruits an...

Geuk (Momordica cochinchinensis spreng) tropical fruits, which are produced in Jeju Island, Korea, well known for containing high levels of carotenoids and α-tocopherol. In this study, geuk fruits were separated two parts (pulp; yellow-orange and seed aril; red). The extracts of geuk fruits were simultaneously analyzed for carotenoids and α-tocopherol contents using HPLC. The results showed tha...

Pepino (Solanum muricatum) also known as pepino dulce or pear melon is a plant that is originally grown in South America, mainly for its juicy fruits. Recently, pepino is successfully cultivated not only in South and North America, but also in Australia, Europe, Asia and the Middle East countries such as Turkey. In Turkey, the pepino crops were found to be well adapted to grow well and with hig...

objective: grape virus diseases are a serious problem in iran. leaves and fruits of grape have been used for different purposes like cooking in iran. the present investigation was carried out to study on the cytotoxic-activities of extracts of fruits and leaves of vitis vinifera from both virus-free and virus-infected grape cultivars against breast cancer cell line (mda-mb-231) and human embryo...
