Dioscorea batatas

Antischistosomal activity. Hot water extract of the dried rhizome, taken orally by human adults at variable dosage levels, was active. A mixture of Rehmannia glutinosa (Rt), Dioscorea batatas (Tu), Dolichos lablab (Sd), Glycyrrhiza uralensis (Rt), Zingiber officinale (Rh), Evodiarutae carpa (Fr), Atractylodes macrocephala (Rh), and Panax ginseng (Rt) was used . ... 

Dormancy in yam bulbs (Dioscorea batatas) was found to be induced by three inhibitors, batatasins I, II, and III (72, 73). The structures for batatasins I and III were assigned recently. Batatasin I is 6-hydroxy-2,4,7-trimethoxyphenanthrene and batatasin III is 3,3-dihydroxy-5-methoxy-bibenzyl. Biogeneti-cally, hydrangenol, lunalaric acid and batatasin III appear to... 

Since the formation of the secondary metabolites of the Monascus spp. is affected by cultivation conditions, Lee et al. (2006) used sweet potato (Ipomoea batatas), potato Solanum tuberosum), cassava (Manihot esculenta), and dioscorea (Dioscorea batatas) as the substrates to identify the best choice for monacolin K production. The results showed that M. purpureus NTU 301, with dioscorea as the substrate, could produce monacolin K at 2584 mg/kg, which is 5.37 times more than that resulted when rice is used as the substrate.

Alkaloids are known in a few members of the family. Tests on 45 samples which included 37 species resulted in three positives in plants known to be alkaloidal (Dioscorea dumetorum, D. hispida, D. alaia) and in two of 13 other unidentified Dioscorea species. The remainder were negative Dioscorea abyssinica, D. alata, D. batatas, D. bucha-nanii, D. bulbifera, D. composita, D. cotinifolia, D. doryophora, D. dregeana, D. esculenla, D. hemicrypta, D. hirtiflora, D. mexicana, D. pentaphylla, D. quartiniana, D. retusa, D. sylvatica, D. trifida, Tamus edulis.
