Flavonoids comprise the majority of mostly studies bioactive substances in propolis. Chrysin (5,7-dihydroxyflavone) is a flavonoid that exists in certain mushrooms, flowers (e.g., blue passion flower), and in other bee products (e.g., honey). It expresses anti-inflammatory, antioxidant, anti-proliferative, and neuroprotective effects [72]. Caffeic acid phenethyl ester (CAPE), a derivative of hydroxycinnamic acid, expresses anti-oxidant, immunomodulatory, anti-inflammatory, antiviral, and ant-neoplastic properties [73,74,75]. Pinocembrin (5,7-dihydroxyflavanone) is the most copious flavonoid in propolis—1 g of balsam/an ethanolic extract from poplar propolis found in Spain contains up to 606–701 mg of pinocembrin [76]. It exists in numerous plants (e.g., Eucalyptus and Populus). It exhibits anti-inflammatory, antioxidant, antimicrobial, and antiproliferative activities [77,78].","tracks":[{"project":"LitCovid-PD-CLO","denotations":[{"id":"T46727","span":{"begin":48,"end":51},"obj":"http://purl.obolibrary.org/obo/CLO_0051582"},{"id":"T23081","span":{"begin":66,"end":73},"obj":"http://purl.obolibrary.org/obo/CLO_0009985"},{"id":"T78989","span":{"begin":93,"end":103},"obj":"http://purl.obolibrary.org/obo/CLO_0001658"},{"id":"T90348","span":{"begin":278,"end":279},"obj":"http://purl.obolibrary.org/obo/CLO_0001020"},{"id":"T23908","span":{"begin":538,"end":539},"obj":"http://purl.obolibrary.org/obo/CLO_0001020"},{"id":"T89614","span":{"begin":1029,"end":1039},"obj":"http://purl.obolibrary.org/obo/CLO_0001658"}],"attributes":[{"subj":"T46727","pred":"source","obj":"LitCovid-PD-CLO"},{"subj":"T23081","pred":"source","obj":"LitCovid-PD-CLO"},{"subj":"T78989","pred":"source","obj":"LitCovid-PD-CLO"},{"subj":"T90348","pred":"source","obj":"LitCovid-PD-CLO"},{"subj":"T23908","pred":"source","obj":"LitCovid-PD-CLO"},{"subj":"T89614","pred":"source","obj":"LitCovid-PD-CLO"}]},{"project":"LitCovid-PD-CHEBI","denotations":[{"id":"T263","span":{"begin":25,"end":29},"obj":"Chemical"},{"id":"T264","span":{"begin":257,"end":273},"obj":"Chemical"},{"id":"T265","span":{"begin":280,"end":289},"obj":"Chemical"},{"id":"T267","span":{"begin":434,"end":445},"obj":"Chemical"},{"id":"T268","span":{"begin":501,"end":529},"obj":"Chemical"},{"id":"T269","span":{"begin":501,"end":513},"obj":"Chemical"},{"id":"T271","span":{"begin":509,"end":513},"obj":"Chemical"},{"id":"T272","span":{"begin":524,"end":529},"obj":"Chemical"},{"id":"T273","span":{"begin":531,"end":535},"obj":"Chemical"},{"id":"T274","span":{"begin":554,"end":574},"obj":"Chemical"},{"id":"T276","span":{"begin":570,"end":574},"obj":"Chemical"},{"id":"T277","span":{"begin":591,"end":598},"obj":"Chemical"},{"id":"T278","span":{"begin":637,"end":646},"obj":"Chemical"},{"id":"T279","span":{"begin":703,"end":725},"obj":"Chemical"},{"id":"T280","span":{"begin":707,"end":725},"obj":"Chemical"},{"id":"T281","span":{"begin":747,"end":756},"obj":"Chemical"},{"id":"T283","span":{"begin":869,"end":880},"obj":"Chemical"},{"id":"T284","span":{"begin":979,"end":990},"obj":"Chemical"},{"id":"T285","span":{"begin":992,"end":1005},"obj":"Chemical"}],"attributes":[{"id":"A263","pred":"chebi_id","subj":"T263","obj":"http://purl.obolibrary.org/obo/CHEBI_23888"},{"id":"A264","pred":"chebi_id","subj":"T264","obj":"http://purl.obolibrary.org/obo/CHEBI_38686"},{"id":"A265","pred":"chebi_id","subj":"T265","obj":"http://purl.obolibrary.org/obo/CHEBI_47916"},{"id":"A266","pred":"chebi_id","subj":"T265","obj":"http://purl.obolibrary.org/obo/CHEBI_72544"},{"id":"A267","pred":"chebi_id","subj":"T267","obj":"http://purl.obolibrary.org/obo/CHEBI_22586"},{"id":"A268","pred":"chebi_id","subj":"T268","obj":"http://purl.obolibrary.org/obo/CHEBI_8062"},{"id":"A269","pred":"chebi_id","subj":"T269","obj":"http://purl.obolibrary.org/obo/CHEBI_16433"},{"id":"A270","pred":"chebi_id","subj":"T269","obj":"http://purl.obolibrary.org/obo/CHEBI_17395"},{"id":"A271","pred":"chebi_id","subj":"T271","obj":"http://purl.obolibrary.org/obo/CHEBI_37527"},{"id":"A272","pred":"chebi_id","subj":"T272","obj":"http://purl.obolibrary.org/obo/CHEBI_35701"},{"id":"A273","pred":"chebi_id","subj":"T273","obj":"http://purl.obolibrary.org/obo/CHEBI_8062"},{"id":"A274","pred":"chebi_id","subj":"T274","obj":"http://purl.obolibrary.org/obo/CHEBI_23401"},{"id":"A275","pred":"chebi_id","subj":"T274","obj":"http://purl.obolibrary.org/obo/CHEBI_24689"},{"id":"A276","pred":"chebi_id","subj":"T276","obj":"http://purl.obolibrary.org/obo/CHEBI_37527"},{"id":"A277","pred":"chebi_id","subj":"T277","obj":"http://purl.obolibrary.org/obo/CHEBI_63248"},{"id":"A278","pred":"chebi_id","subj":"T278","obj":"http://purl.obolibrary.org/obo/CHEBI_22587"},{"id":"A279","pred":"chebi_id","subj":"T279","obj":"http://purl.obolibrary.org/obo/CHEBI_28157"},{"id":"A280","pred":"chebi_id","subj":"T280","obj":"http://purl.obolibrary.org/obo/CHEBI_38749"},{"id":"A281","pred":"chebi_id","subj":"T281","obj":"http://purl.obolibrary.org/obo/CHEBI_47916"},{"id":"A282","pred":"chebi_id","subj":"T281","obj":"http://purl.obolibrary.org/obo/CHEBI_72544"},{"id":"A283","pred":"chebi_id","subj":"T283","obj":"http://purl.obolibrary.org/obo/CHEBI_28157"},{"id":"A284","pred":"chebi_id","subj":"T284","obj":"http://purl.obolibrary.org/obo/CHEBI_22586"},{"id":"A285","pred":"chebi_id","subj":"T285","obj":"http://purl.obolibrary.org/obo/CHEBI_33281"},{"subj":"T263","pred":"source","obj":"LitCovid-PD-CHEBI"},{"subj":"T264","pred":"source","obj":"LitCovid-PD-CHEBI"},{"subj":"T265","pred":"source","obj":"LitCovid-PD-CHEBI"},{"subj":"T267","pred":"source","obj":"LitCovid-PD-CHEBI"},{"subj":"T268","pred":"source","obj":"LitCovid-PD-CHEBI"},{"subj":"T269","pred":"source","obj":"LitCovid-PD-CHEBI"},{"subj":"T271","pred":"source","obj":"LitCovid-PD-CHEBI"},{"subj":"T272","pred":"source","obj":"LitCovid-PD-CHEBI"},{"subj":"T273","pred":"source","obj":"LitCovid-PD-CHEBI
