Process for preparing streamed Liriopis tuber with increased content of physiologically active substance

摘要

PURPOSE: A manufacturing method of Liriope platyphylla with increased contents of bioactive substances is provided by steaming the Liriope platyphylla dried root for a predetermined time at certain temperature, and drying for multiple times. CONSTITUTION: Foreign substance on the dried root of Liriope platyphylla is removed. The dried root of the Liriope platyphylla without the foreign substance is steamed for 6-24 hours at 80-120 deg. C. The steamed Liriope platyphylla is hot air dried for 60-80 hours at 60-80 deg. C, and lyophilized for 45-55 hours at 90-70 deg. C below zero. The foreign substance on the dried root of the Liriope platyphylla is removed. he dried root of the Liriope platyphylla without the foreign substanceis steam processed for 1-3 hours at 80-120 deg. C, and dried. The process of steaming and drying are repeated for 3-9 times. The steamed liriope platyphylla is dried. The steamed Liriope platyphylla has 4-8 times higher content of crude saponin contents, the total phenol materials, and the total flavonoid than Liriope platyphylla without the steaming process.
