Lablab bean

Lablab purpureus (family Leguminosae Papilionoideae) Lablab bean is indigenous to South-East Asia and has been introduced in Africa and other tropical and subtropical countries. It is eaten cooked, as dhal, and sometimes used as a substitute for broad beans in the preparation of fried bean cake tanniah ...

In 1982 Yokota et al. isolated 160 pg of dolicholide (31) and 50 pg of dolichosterone (34) from 34 kg of the immature seeds of a bean, Dolichos lablab.12 So as to confirm the proposed structures, we synthesized these brassinosteroids as shown in Figure 2.24.68,73,74 In this case, too, we used organoaluminum chemistry and epoxide cleavage as the key reactions. 

Dolichosterone. Dolichosterone is the methane derivative of caststerone and differs from the brassinolide structure by the absence of the lactone function in the B-ring and by having a methylene rather than a methyl function at C-24. The brassinosteroid was isolated from immature seeds of Dolichos lablab (hyacinth-bean)... 

Dolichin, an antifungal protein (Mr 28 kDa) isolated from the seeds of the field bean Dolichos lablab. It shows structural resemblance to chitinases, which also exhibit antifungal activity. Dolichin shows antifungal activity against Rhizoctonia solani, Fusarium oxysporum, and Coprinus coma-tus. Furthermore, dolichin is able to inhibit HIV reverse transcriptase, and a- and fi-glucosidases associated with HIV infection...

Phaseolus lunatus beans (lima bean, Java bean) contain the cyanogenetic gluco-side phaseolunatin, which is extremely toxic when hydrolysed. The glucoside is present, but only in small quantities, in cultivated varieties of P. lunatus such as the butter bean. A number of species, including Cicer ensiformis, Dolichus biflorus, D. lablab, P lunatus, P. vulgaris and P. communis, are known to contain lectins, which are toxic...
