garcinia mangostana/抗氧化剂

Characterisation of antioxidant fraction of the fruit of Garcinia gummi-gutta was done using liquid chromatography mass spectroscopic (LC/MS) analyses. Total poly phenolics and radical scavenging activity of various extracts such as acetone, methanol and hydroalcohol were estimated

A new xanthone, namely garcinexanthone G (1), along with eight known compounds, stigmasta-5,22-dien-3β-ol (2), stigmasta-5,22-dien-3-O-β-glucopyranoside (3), 3β-acetoxy-11α,12α-epoxyoleanan-28,13β-olide (4), 2,6-dimethoxy-p-benzoquinone (5), 1,3,5-trihydroxy-2-methoxyxanthone (6),

Total phenolic content (TPC) and antioxidant properties of xanthone extract from mangosteen pericarp via microwave-assisted extraction (MAE) method was optimized by response surface methodology (RSM). The MAE extraction conditions to obtain optimum antioxidant-rich xanthone extract were at 2.24 min

Crude extracts (methanol) of various parts, viz. the leaves, fruits, roots, stem and trunk bark, of Garcinia atroviridis were screened for antimicrobial, cytotoxic, brine shrimp toxic, antitumour-promoting and antioxidant activities. The crude extracts exhibited predominantly antibacterial activity

The bark extracts of Garcinia pedunculata and Garcinia cowa, which are abundant in the Northeastern regions of India, were screened for their antioxidant and in vitro antiplatelet aggregating activities. By β-carotene linoleate model for antioxidant assay, acetone extract of G. pedunculata and

OBJECTIVE Pancreatic cancer (PC) is the most aggressive malignant disease, ranking as the fourth most leading cause of cancer-related death among men and women in the United States. In this study, we provide evidence of chemotherapeutic effects of α-mangostin, a dietary antioxidant isolated from the

Investigation on the structure--antioxidative activity relationships of derivatives based on garcinoic acid from Garcinia kola (Guttiferae) led to discovery of a powerful antioxidative agent.

Garcinia parvifolia belongs to the same family as mangosteen (Garcinia mangostana), which is known locally in Sabah as "asam kandis" or cherry mangosteen. The present study was conducted to determine the phytochemicals content (total phenolic, flavonoid, anthocyanin, and carotenoid content) and

BACKGROUND Garcinia spp. belongs to the family Clusiaceae has been traditionally used for the treatment of many ailments including the liver damage. Garcinia dulcis found in North Eastern region of Assam; India can be a potential candidature to combat different ailments. Objective: The present work

Mangosteen peel is a source of natural phenolic antioxidants. During processing, the quality and quantity of these compounds in the final product are altered. Sometimes, the important causal relationships are not easy to establish and thus process management is difficult. This is especially true

METHODS Three fluorescence biosensors were developed based on a 3T3-L1 preadipocyte line that stably expressed Nfkb-RE/GFP, Fabp4-P/CFP, and Nrf2-P/YFP fluorescent reporters. We hypothesized that nutraceuticals' inflammatory, adipogenic, and antioxidant status will be identified based on the change

The present study revealed that the latex of Garcinia morella (Gaertn.) possessed 204.27 mg/g phenolic acid and 124.92 mg/g of flavonoid content along with other phytochemicals. Gas chromatography-mass spectrometry (GC-MS) revealed the presence of 20 compounds in the latex, with the major compounds

The composition of the volatile oil obtained by hydrodistillation from the fruit peel of Garcinia brasiliensis (Mart.) Planch. et Triana was determined by GC/MS. A total of 38 components were identified, including gamma-muurolene (10.3%), spathulenol (8.7%), delta-cadinene (8.3%), torreyol (8.0%),

BACKGROUND The number of patients who seek orthodontic treatment that may have a history of tooth bleaching is increasing over the time. Bleaching may influence the decrease of the bond strength of orthodontic brackets. OBJECTIVE To determine and prove the effect of mangosteen peel (MP) extract to

Many polyphenols bind proteins, therefore our research was focused on the potential of protein binding to polyphenols of investigated fruits and their health-related effects. The contents of polyphenols and related antioxidant activities of traditional, citrus and exotic fruits were compared. The
