Anthocyanins And Flavonoids Of Vaccinium L., Zushang Su
Anthocyanins And Flavonoids Of Vaccinium L., Zushang Su
Faculty Publications
Vaccinium L., comprising approximately 450 species primarily in the Northern Hemisphere, is a genus of shrubs or lianas in the family Ericaceae. The berries of many species are harvested for household consumption and commercial sale. The genus produces a wide range of compounds such as anthocyanins, flavonoids, chromones, coumarins, lignans, benzoic acids, iridoids, sterols, and triterpenoids, but is best known for the production of anthocyanins and flavonoids. Extracts and isolates of anthocyanins and flavonoids from Vaccinium fruits or leaves showed antioxidative, anti-inflammatory, antitumor, antiviral, vasoprotective, and antifungal activities. To data, more than 116 anthocyanins and flavonoids compounds have been isolated …
Phytochemical Constituents And Pharmacological Activities Of Eryngium L.(Apiaceae), Ping Wang, Zushang Su, Wei Yuan, Guangrui Deng, Shiyou Li
Phytochemical Constituents And Pharmacological Activities Of Eryngium L.(Apiaceae), Ping Wang, Zushang Su, Wei Yuan, Guangrui Deng, Shiyou Li
Faculty Publications
Eryngium L. is the largest and arguably the most taxonomically complex genus of the family Apiaceae. The genus has approximately 250 species throughout the world, with the center of diversity in South America. Some Eryngium species are cultivated as ornamental, vegetable, or medicinal crops for folk uses. With increasing chemical and biological investigations, Eryngium has shown its potential as pharmaceutical crops. This review focuses on phytochemistry and pharmacological activities of 127 compounds isolated and identified from 23 species of Eryngium, particularly nonessential oil compounds such as terpenoids, triterpenoid saponins, flavonoids, coumarins, polyacetylenes, and steroids. Eryngium extracts or isolates have shown …
Preparation And Characterization Of A Standardized Anticonvulsant Ginseng Rb Extract From Panax Quinquefolius L., Xiao-Yuan Lian, Zhizhen Zhang
Preparation And Characterization Of A Standardized Anticonvulsant Ginseng Rb Extract From Panax Quinquefolius L., Xiao-Yuan Lian, Zhizhen Zhang
Faculty Publications
A ginseng Rb extract (GRbE) containing three major ingredients of ginsenoside Rb1 (G-Rb1), ginsenoside Rb3 (G-Rb3) and ginsenoside Rd (G-Rd) has been shown to have anticonvulsant and neuroprotective activity. As such, sufficient characterization and standardization of this active GRbE are demanded to facilitate an ongoing preclinical investigation on its potential for the treatment of epilepsy. In the investigation, the methods for generating the active GRbE and isolating G-Rb1, G-Rb3, and G-Rd in large scale from Panax quinquefolius are described. The chemical profile of GRbE was characterized by identifying the structure of the individual ingredients using NMR, and the concentration of …
Chemical Composition And Product Quality Control Of Turmeric (Curcuma Longa L.), Shiyou Li, Wei Yuan, Guangrui Deng, Ping Wang, Peiying Yang, Bharat Aggarwal
Chemical Composition And Product Quality Control Of Turmeric (Curcuma Longa L.), Shiyou Li, Wei Yuan, Guangrui Deng, Ping Wang, Peiying Yang, Bharat Aggarwal
Faculty Publications
Chemical constituents of various tissues of turmeric (Curcuma longa L.) have been extensively investigated. To date, at least 235 compounds, primarily phenolic compounds and terpenoids have been identified from the species, including 22 diarylheptanoids and diarylpentanoids, eight phenylpropene and other phenolic compounds, 68 monoterpenes, 109 sesquiterpenes, five diterpenes, three triterpenoids, four sterols, two alkaloids, and 14 other compounds. Curcuminoids (diarylheptanoids) and essential oils are major bioactive ingredients showing various bioactivities in in vitro and in vivo bioassays. Curcuminoids in turmeric are primarily accumulated in rhizomes. The essential oils from leaves and flowers are usually dominated by monoterpenes while those from …

Anthocyanins, Phenolics, And Antioxidant Capacity Of Vaccinium L. In Texas, Usa, Wei Yuan, Lijing Zhou, Guangrui Deng, Ping Wang, David Creech, Shiyou Li
Faculty Publications
Berries of Vaccinium spp. have long been an important source of food and pharmaceutical ingredients and are considered to have high antioxidant potential. Growing blueberries in Texas, United States is a substantial industry, but there is no report on their antioxidant capacity, total phenolics, and anthocyanins. This study evaluates antioxidant capacity and contents of total phenolics and anthocayanins in both fruits and leaves of 19 genotypes including five commercial cultivars and 11 selections of rabbiteye blueberry (V. ashei) and southern highbush (V. corymbosum hybrids), and three native species (V. darrowii, V. arboreum, and V. fuscatum) grown in Nacogdoches, Texas. Significant …

An Overview Of Genus Aesculus L.: Ethnobotany, Phytochemistry, And Pharmacological Activities, Shiyou Li, Xiao-Yuan Lian, Zhizhen Zhang
Faculty Publications
The genus Aesculus L. (Hippocastanaceae) has 12 species distributed in eastern Asia, eastern and western North America, and Europe. In Europe and the United States, A. hippocastanum has been used for the treatment of chronic venous insufficiency, hemorrhoids, and postoperative edema. In China, A. chinensis var. chinense has been used as a stomachic and analgesic in the treatment of distention and pain in the chest and the abdomen, malaria, dysentery, and heart disease. The objective of this paper is to review the ethnobotany, phytochemistry, and pharmacological properties of the genus Aesculus. To date, more than 210 compounds have been isolated …

Pharmaceutical crops is an ambiguous term used by biologists and chemists for different categories of plants. We define pharmaceutical crops as those cultivated species that are used for extraction or preparation of therapeutic substances such as active pharmaceutical ingredients (APIs), excipients used in pharmaceutical formulations, vaccines and antibodies, as well as other therapeutic proteins. Based on the type of pharmaceutical product, these crops can be classified into three distinct yet sometimes overlapping categories: crops for the production of small therapeutic molecules (STMs), large therapeutic molecules (LMTs), or standard therapeutic extracts (STEs). This review briefly discusses the relationships of pharmaceutical crops …
