Pseudohypericin (CAS 55954-61-5) is a naturally occurring naphthodianthrone found in St. John\u2019s wort (Hypericum perforatum<\/em><\/a>). As a close structural analog of hypericin, it is one of the characteristic bioactive constituents of this well-known medicinal plant and contributes to the phytochemical profile used in herbal extracts and supplements.<\/p>\r\n
Naphthodianthrones, including pseudohypericin, have been extensively studied for their potential roles in supporting human health research, particularly in the areas of photodynamic activity, antioxidant properties, and modulation of biological pathways. Pseudohypericin serves as an important marker compound for the standardization and quality control of St. John\u2019s wort extracts used in dietary supplements, nutraceuticals, and herbal products. In vitro and preclinical research has explored its biochemical interactions and complementary activity with other Hypericum constituents.<\/p>\r\n
Planta Analytica provides high-purity pseudohypericin as an analytical reference standard to enable accurate quantification, method validation, and extract standardization in laboratories worldwide.<\/p>","post_title":"Pseudohypericin","post_excerpt":"[wc_measurement_price_calculator_pricing_table]","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"pseudohypericin","to_ping":"","pinged":"","post_modified":"2026-04-10 12:52:12","post_modified_gmt":"2026-04-10 16:52:12","post_content_filtered":"","post_parent":0,"guid":"http:\/\/159.69.28.184\/product\/pseudohypericin\/","menu_order":0,"post_type":"product","post_mime_type":"","comment_count":"0","filter":"raw"}],"post_count":2,"current_post":-1,"before_loop":true,"in_the_loop":false,"post":{"ID":4969,"post_author":"6","post_date":"2023-11-16 09:29:17","post_date_gmt":"2023-11-16 09:29:17","post_content":"Hypericin (CAS 548-04-9) is a photosensitive antiviral, anticancer, and antidepressant agent derived from Hypericum perforatum<\/em> (St. John's wort<\/a>).
