The physiological activity of the extracts from 107 Chinese plants in shortening the last larval instar of the silkworm Bombyx mori L. was first tested through oral administration; and thin layer ehromatography was followed to separate the active principles when pronounced effects had heen noticed. It is found that Lamium barbatum (Family Lahiatae) can serve as a new source of phyto-ecdysone which amounts to 0.029% of the dry weight of the whole plant. The instrumental analytical data assign it to be β-ecdysone. The phyto-ecdysones obtained from extraction are to be used in sericultural practice to shorten the last larval instar for regulation of silk production of the silkworm. It is found that to feed the last instar larvae with mulberry leaves sprayed with cyasterone in extravagant dosage (above 5 μg per larva) will give rise to intermediate forms between larvae and pupae while a proper dosage (1.5 μg per larva) will cause to yield normal larvae.

(1)通过107种植物对家蚕的脱皮活性试验,发现唇形科植物野芝麻(Lamium barbatum S.etZ.)是一种新的含蜕皮激素的植物。蜕皮激素收得率是0.029%,熔点239—242℃,TLC Rf 0.5—0.6(黄绿色),并经光谱分析证明为β-蜕皮激素。 (2)从资源丰富的植物土牛膝(Achyranthes bidentata Bl.)中提取了β-蜕皮激素,并进行了蚕用试验与推广应用研究,证明活性及效果稳定,并提出了简易的制作生产方法。 (3)在试验中发现从川牛膝(Cyathula capitata Moquin-Tandon)根提取的Cyasterone给蚕添食大剂量(5微克/头或以上)时蜕变为幼虫-蛹混合型,而添食小剂量(1.5微克/头)蜕变为正常的蛹。

β-Ecdysone was incorporated into medium for anther culture of wheat, and its influences on induction of pollen plantlets had been observed. β-ecdysone at 0.5-10 mg/l increases the induction-frequency of pollen embryoids and callus which can grow directly into plantlets. Kinetin at 1-10 mg/l inhibits this effect. β-ecdysone plus 2,4-D give a higher induction-frequency of callus which, however, can not differentiate directly on this medium. The combination of β-ecdysone at 1 mg/l with NAA at 1-5 mg/l gives the...

The combination of β-ecdysone at 1 mg/l with NAA at 1-5 mg/l gives the highest induction-frequency of pollen plantlets. These plantlets have a higher viability when planted in soil. Cytological observations of pollen development in anther culture were made.

β-蜕皮激素加入小麦花药培养基中,观察到它对花粉苗诱导的影响。0.5~10毫克/升β-蜕皮激素提高了花粉胚和愈伤组织诱导率,它们能直接长成小苗。1~10毫克/升激动素抑制这种作用。β-蜕皮激素加2,4-D能得到高的愈伤组织诱导率,但这些愈伤组织不能在原培养基上直接分化成苗。β-蜕皮激素1毫克/升与萘乙酸1~5毫克/升相配合产生最高的花粉苗诱导率。这些小苗移入土中容易成活。对花药培养中花粉发育过程进行了细胞学观察。
