Objective: To investigate the chemical constituents from the tubers of Ipomoea batata.
Methods: The chemical constituents were isolated and purified by solvent extraction together with various chromatographic techniques. The structures were elucidated on the basis of physiochemical property and spectral data.
Results: 6 compounds were identified from the CHCl3 extract as Batatinoside I (1), citrusin C(2), octadecyl caffeate (3), beta-amyrin acetate (4), caffeic acid (5), scopoletin (6).
Conclusion: Compound 1 is isolated from Ipomoea batata for the first time.

Polysaccharides from the dried tuber of Typhonium giganteum Engl. (TGEPs) were obtained by utilizing ultrasonic-assisted extraction (UAE) as the extraction method. The determination of optimal process parameters for the UAE of TGEPs (TGEP-U) was accomplished through the application of response surface methodology (RSM).

Article Synopsis
- Kudzu is a perennial vine in the Leguminosae family, with puerarin as its key active ingredient known for various pharmacological benefits.
- The study explores essential questions about the medicinal use of kudzu roots, including why they remain unpeeled and why they are harvested in winter.
- Researchers utilized metabolomics and transcriptomics to identify genetic factors involved in puerarin biosynthesis, establishing a regulatory network aimed at enhancing the production of high-quality kudzu with increased puerarin levels.

Trifoliate yam (Dioscorea dumetorum) is traditionally used to treat diabetics in Nigeria. However, almost no information is available on its antidiabetic constituents and their natural variance. Hence, the activity of methanolic tuber extracts of 67 trifoliate yam accessions from the largest collection in Africa was proven by four colorimetric antidiabetic and antioxidant in vitro assays, as diabetes is also linked with oxidative stress.

Traditional herbalists have been relied on for many years by Algerians to cure a wide range of diseases. Regardless of their nutritional values, mushrooms have chemical properties that make them attractive, beneficial, and more likely to be studied by researchers, according to ethnobotanical literature on traditional phytotherapy. Among all the edible mushrooms, tubers are a type of fungus that are traditionally used in fine dining and have garnered attention recently because of their many therapeutic applications.
