Twenty-seven com pounds in clud ing eight long-chain hy dro car bons, 1-hexacosanol (1), 1-octacosanol (2), palmitic acid (3), stearic acid (4), oleic acid (5), linoleic acid (6), heptacosyl eicosanate (7), glyceryl--tetraeicosanoate (8); three ster ols, -sitosterol (24), stigmasterol (25), -sitosteryl-3-O-D-glucopyranoside (26); one triterpene, lupeol (27); eight anthraquinones, chrysophanol (9), emodin (10), physcion (11), citreorosein (12), rhein (13), rhein methyl es ter (14), ziganein (15), 1,4,5-trihydroxyanthraquinone (16); two coumarins, isoscopoletin (17), scopoletin (18); two chromones, 2,5-dimethyl-7-hydroxychromone (19), 2,5-dimethyl-7-methoxychromone (20); three ar o matic com pounds, isovanillic acid (21), vanillic acid (22), and 2,4-dihydroxybenzaldehyde (23), were iso lated and iden ti fied from the bark of Cassia fis tula. Their structures were de ter mined on the ba sis of spec tral data. IN TRO DUC TIONCassia fis tula L (Leguminosae) is widely dis trib uted in In dia, the Phil ip pines, South China and Tai wan. It has long been used as folk med i cine to treat gas tri tis and make in sec ticide. 1 Chem i cal com po nents of this plant have been ex tensively in ves ti gated; flavanoids, oxyanthraquinones, sug ars, and triterpenoids have been re ported from its leaves, flow ers, trunk, and fruit. 2-6 Be cause of the in ter est on the ac tive compo nents of anthraquinones, we have in ves ti gated the aril of this spe cies, and found twenty-seven com pounds in clud ing eight anthraquinones, eight long-chain hy dro car bons, four ster ols, one triterpene, two coumarins, two chromones, three ar o matic com pounds, and five sug ars. In this pa per, we reported the iso la tion and char ac ter iza tion of chem i cal con stitu ents from its arils. RE SULTS AND DIS CUS SIONThe methanolic ex tracts of dried aril of C. fis tula L. were con cen trated to ob tain res i due and it was par ti tioned between CHCl 3 and H 2 O. The aque ous layer was sub se quently ex tracted with n-BuOH. CHCl3 and n-BuOH lay ers were concen trated and then sub jected to chro ma tog ra phy. They allowed the iso la tion of 1-hexacosanol ( 1), 7 1-octacosanol (2), 7 palmitic acid (3), stearic acid (4), oleic acid (5), 8 linoleic acid (6), 9 heptacosyl eicosanate (7), 10 chrysophanol (9), 11 phys cion (11 ), 12 rhein methyl es ter (14), 13 ziganein (15), 14 -sitosterol (24), 15 stigmasterol (25), 15 lupeol (27) 8 from the CHCl3 sol u -2,5-dimethyl-7-meth oxy chromone (20), 21 vanillic acid (22), 23 2,4-dihydroxybenzaldehyde (23), 24 glyceryl-1-tetracosanoate (8), 25 -sitosterol-D-glucoside (26), 9 from the n-BuOH sol u ble frac tion, The struc tures of these com pounds were de ter mined on the ba sis of spec tral data, chem i cal derivatization and com par i son with au then tic sam ples.The char ac ter is tics of anthraquinones are the col ored solid state (yel low to red) and the ap pear ance of C-1, -4, -5, or -8 hydroxyl group sig nal at H ~12 (hy dro gen bond ing).

“…The control of growth and opening of a flower bud is not well understood and several serious gaps exist in our knowledge. Endogenous gibberellin levels seem to regulate flower growth (Jeffcoat, Scott and Harris, 1969;Sircar et al, 1970;Murakami, 1973Murakami, , 1975. Removal of stamens results in inhibition of corolla expansion.…”

Specificity of Gibberellin and Sucrose-promoted Flower Bud Growth in Gladiolus

A critical stage in flower bud growth in the spike of Gladiolus which is initiated by gibberellic acid (GA 3) and sustained by sucrose has been identified. This corresponds to the stage at which separation of the outer bract occurs. In buds at different developmental stages isolated and held in water, it is the same bud stage that first shows increased growth. Buds not induced by light were shown to respond more significantly to GA 3 and sucrose than those induced by light. Since the separation of the outer bract results in light-induced amylase production and starch hydrolysis leading to petal growth, it is proposed that growth promotion by GA 3 is related to light-induced petal growth at this specific stage.

“…After differentiation of these organs is completed, there is no abortion in roses (Moe 1971a). The various fiower organs can serve as a source of different growth substances, such as auxins (Lang 1965) and gibberellins (Jeffcoat et al 1969, Jeffcoat and Cockshull 1972, Jones and Phillips 1966, Sircar et al 1970. The atrophy of these organs may be responsible for the drop in content of growth substances in the leaves of non-fiowering shoots.…”

Flower Bud Atrophy in Baccara Roses

Physiologia Plantarum

The activity of various growth substances in the upper leaves of Baccara roses was compared between flowering and non-flowering shoots. Flowering shoots had a higher level of gibberellins, auxins and cytokinins. The changes in level of these growth substances during different stages of shoot development were more marked in flowering than in non-flowering shoots. The level of inhibitors was higher in leaves of "blind" shoots. At least two inhibitors are present; one of them was identified as abscisic acid, while the other appears in the neutral fraction.
