Studies on the constituents of the seeds of hernanadia ovigera



Studies on the constituents of the seeds of hernanadia ovigera



Yakugaku Zasshi 99(6): 674-677



Four kinds of lignans were isolated from the seeds of H. ovigera L. collected in Okinawa [Japan], besides the previously reported desoxypodophyllotoxin. An oily substance II named bursehernin, C21H22O6, was confirmed to be lignan-2 isolated from Bursera schlechtendalii. Two compounds, mp [melting point] 171-173.degree., and mp 125-126.degree., were determined as desoxypicropodophyllin and podorhizol obtained from Podophyllum emodi Wall., respectively. One compound, mp 270-275.degree., could not be clarified due to its small amount.
