Fuzzy clustering algorithms for identification of Exocarpium Citrus Grandis through chromatography
Soft Computing, 2015Chromatography has been extensively applied in identification and quality control of Chinese medicines (CMs). However, regular analytical methods are not suitable if labeled patterns or reference patterns are not available. Unsupervised and semi-supervised recognition approaches for chromatographic patterns, namely nonrandomized fuzzy C-Means ...

Pigment and Ultrastructural Changes in the Developing Pummelo Citrus grandis 'Goliath'
Botanical Gazette, 1983Pigment changes in the flavedo and endocarp of the developing pummelo, Citrus grandis `Goliath,' were investigated at four ripening stages: green, color break, almost ripe, and fully ripe. In the flavedo, chlorophyll of the green fruit decreased abruptly and was totally absent in the fully ripe, lemon-yellow fruit, which contained only carotenoids ...

Limonoids in Pummelos [Citrus grandis (L.) Osbeck]
Journal of Food Science, 1995ABSTRACT Juice and seeds from 16 cultivars of mature pummelo fruits were analyzed for limonoid content. Pummelo juice contained an average of 18 ppm limonin and 29 ppm total limonoid glucosides. Compared to other juices, ptmnnelo contained very high concentrations of limonin and very low concentrations of limonoid glucosides. Limonin,

Optimization of pectin extraction from dried peel of citrus grandis
Polymer Bulletin, 1989The influence of acid concentration, temperature, and extraction time on pectin extracted from dried peel of Citrus grandis have been investigated. The dependence of pectin yield and of the relative viscosity of pectin solution on experimental conditions has been described by mathematical models.
